FINALLY. My teacher sucks at teaching. All year the whole class has been confused because he moves too fast. We are an honors class, so we are used to fast paced work, but he literally didn't explain ANY of this. He just wrote a bunch of notes on the board super quick and said "Got it? Good." He didn't even explain what stoichiometry was trying to show, so I didn't even understand what I had to do and why. That's why I wound up having to look it up on my own, as I have to pass this class. This video taught me more in fifteen minutes than my teacher has all week, so thank you for making it. It helped me greatly, and I'm finally beginning to understand how to work these problems out. I'll have to show the notes I took to the rest of my class so we can all actually pass the next test.
Im in physical science honors and my teacher is showing me this😭😭😭 He doesn’t teach either. He teaches like his college professors, which don’t teach. They just present a bunch of information to you. All the notes I have on stoichiometry for his class because he didn’t even bother define it is an example of how many cups of eggs do 100 pancakes require. The rest of the time he just spent playing video games. So many people have already gone to the head to say he’s not a good teacher. I have too, my dad has, but nothing works. He just gets worse and worse.. He expects us to already know this and do it ourselves.
I'm taking chem right now, and I thought Stoichiometry is going to kill me, but not after watching this video. It's so simple and easy to understand, why can't our teacher be the same and show us step by step once to actually understand what Stoichiometry means. Thank you so much for this lecture, I'm sure it will help a lot of students that are confused like I was.
Fr, it felt like I was the only one lost because I couldn't figure out how to balance the equations properly but with that simple tip of making sure everything can cancel, the problem clicks in my mind now. Hope you finished your Chem with a good grade!
you may have saved my ass here, I've got a test on this in 2 days, if I fail I can't take the exam, which would ruin the semester. I just learned more in 15 minutes of your video than in 3 lectures combined, so thank you.
I think I'll be doing this more often, the fact that you can just pause a video and give yourself time to figure it out makes it so much better than lectures... try pausing a lecture :D Again, thanks a ton my friend, you may well have saved me from having a really bad day.
nj4ck i totally agree with you, I'm in summer school right now which i actually kind of like better than regular school because they have videos and such, but they just completely failed to teach stoichiometry to me and i just didn't understand it, thank you so much for this
COMPLETELY AGREE WITH THIS COMMENT : you may have saved my ass here, I've got a test on this in 2 days, if I fail I can't take the exam, which would ruin the semester. I just learned more in 15 minutes of your video than in 3 lectures combined, so thank you. thankkkkkk god
@@om-rane Lmaooo. I’m currently struggling right now. Our test was cancelled because he failed to provide us with the adequate answers and way of doing stoichiometry. Plus, he’s about to get fired
@@artistically_pain3876 oof, mine just goes off on religious tangents instead of teaching and sometimes isnt even there cause he has to help his son or something (the son was also a teacher at the same school) who got fired to telling a kid he would kill him
Had one of those lovely moments where you have no clue how to do it then somebody who can explain complex things like this comes along and just teaches you. Thanks a lot. First bit of chem I’ve had trouble with but thanks to you it’s easier now.
OMG. I had no clue how to do this. I watched so many other youtube videos and none of them explained them better than you did. THANK YOU. Btw are you a teacher because you should be. :D
Either lecturers are being paid to take simple problems and make them look so difficult. Or you just excel at making the difficult look so easy Sir. Thank you so much, this sure gave me a better understanding of stoichiometry
you had me at "mathematically", thank you so much for this. as someone in math as high as third dimension calculus, struggling with beginner's chem has been humbling. this was very helpful!
This is an interesting comment for me (sorry for the belated reply). My students in higher level math, like you, often struggle a bit, and I always assume it is the difference between manipulating numbers as abstractions (in a math class) versus manipulating numbers that have been given meaning through units and measurement (in chemistry or other science). It seems to require a different part of the brain.
This is such an great explanation, it is patient and careful in explain the fundamentals of why we are doing what we are doing and how it works on a molecular level giving the viewer meaning to what he is doing and a deeper understanding. Your pace of speaking and tone is perfect and the animations give a great visual representation. You are a great educator, if only the 10,000s of thousands of dollars i spend at college would afford me a professor with your abilities.
bro ive taken 3 chem classes and have NEVER been able to understand stoichiometry but this was SO SIMPLE. wish professors just understood how to actually cater to students. thank u king
bro tysm litteraly my chem class been going over this for like two weeks now and i barely understood a thing. This video helped a ton. Got a quiz on it tomorrow
This is one of the best explanations of stoichiometry that I've seen anywhere. Very clear and very useful. I particularly like the central examples given from 5:00 to 10:30. Excellent! Thank you!
This is seriously such a lifesaver!! For weeks I have gotten help from teachers, multiple tutors, and countless TH-cam videos on how to do stoichiometry. Rather than starting simple they unleashed it upon me and I had no idea what it was conceptually or mathematically. Now that i know WHY it is so much easier!! Thank you for making it so easy to understand and for being so concise and detailed. It seriously helps so so so much! Much appreciation x
what helped me the most was that chart where it told you for mass volumes and etc, this helped me more than my teacher who taught a whole lecture. 14:48
I have degrees in Chemistry and Chemical Engineering and was trying to explain the subject to my son without much success. He understood it and did all the problems in his book after 15 minutes of watching your video! You have obviously a gift. Thank you!
you're amazing. i'm watching this to refresh my memory but you're better than EVERY SINGLE professor I had for inorganic chem. thank you! please teach an Ochem1
@@dennzzy1567 why would it be?

Worst username. Best teaching technique. After 10 years I finally get it. I couldn't understand it in high school, I couldn't understand it in college. Your very well-layed-out video was the perfect tool to learn this. Thank you so much!
holy crap. I have been in class for weeks not knowing what they are doing but as soon as I reach the 5 minutes 45-second mark on your video I understand exactly how everything works. seriously I really hope you continue to succeed.
Thank you so much for this. I'm trying to finish an online Honors Chemistry course so I can be placed in AP the upcoming school year and this video helped me so much. The online program I'm taking is awful. There's so many typos and it's just ridiculous. Thank you once again for this video!
very very helpful. I hardly have time to pay attention plus have to pay 100 to practice, but I do my civil work instead, this helps out so much please keep coming with videos, subscribing as well.
Man this is way damn easier than the way my science teachers describe it. I hate how teachers in public schools always like to mess around with different "ways of teaching" based on how well it works with one school. -.-
My teacher has been teaching this stuff for a week but I didn't understand even a fraction of what she was saying. Now I just learnt the whole unit in 15 minutes! You sir are a GOD.
In India we solve stoichiometric problems with unitary method which is very confusing and time consuming....thanks a lot once again...hope u will post more videos like this
I am in tears! Thank you so much. I have watched video after video and yours is the first one to finally click everything in place. You are amazing. THANK YOU!
YOU SAVED ME!!! Thank you so very much for this video. I have heard so many lectures, watched so many videos, read chapter after chapter, AND NOW FINALLY I UNDERSTAND! I am far from being able to fly through this like others I envy, but as long as I have a map - I WILL GET THERE! Again sir, Thank you!
I have spent an entire semester studying various concepts in General Chemistry. All semester, Stoichiometry problems remained one of those concepts that I only memorized how to solve but understood nothing about the concept of its applications. Thanks to your video, I now understand what I'm doing with all these numbers and conversions. Thank you so much. You are VERY good at explaining the subject. Subscribed, and wishing you all the best.
I have always struggled with stoichiometry ever since I learned it in my sophomore year of high school, now Im a freshman in college and still struggle to understand it until I stumbled across this video. This is the greatest explanation of stoichiometry I have ever seen. Thank you so much
Did not expect to finally understand and be able to do stoichiometry tonight… Usually I’m not very receptive towards watching videos to study, but man, there’s something riddled in your video that worked like a charm on me! Thank you so much for this video hahaha.
My professor hasn't been teaching us the material and expects us to still teach it to ourselves. Thank you, this video saved me from having a breakdown.
yooo, i am taking chemistry right now (sophomore) in high school and after an entire month of sitting through lectures that did not work nor make sense, you've summed up an entire lesson in just 15 minutes, this is amazing. thank you so much, you've saved my life. if lessons were this simple damn, imagine how much schools could fit into cirriculums with teachers like you who know how to fucking teach.
You have saved me on this topic with that simple to follow chart at the end of the video. I am a highschool student who just didn't understand the topic... I'm in college prep and my mom wont let me switch down, so I'm stuck... I have a test tomorrow as I type this, and I have to know it by then... I had tried tutorials with my teacher, but she just brushed me off. I've looked at other videos, but you and this simple to follow method are lifesavers to me... Thank you so much, please keep doing what you do, you've truly saved a poor student's life from an angry mother and a humiliating bad grade. Thanks!
I have searched everywhere but didnt get satisfactory explanation Your yt channel's name CRASH CHEMISTRY Is undoubtedly not a clickbait Like others Lol 😂 Although keep making such vidoes
Fingers crossed: I was struggling all week trying to 'get' what the lectures were about and gave up all hope. THEN I found a 'cheat sheet' he gave at the beginning of the course that cracked this open a little but "not quite there". But THIS all puts it together into a single thing and makes more sense. I checked his notes and could see where he was KINDA saying these things but not so clearly as you did. I mean I feel confident now to take my test (today or tomorrow by midnight) than I did. I still expect to flop it but at least I feel as if I have somewhat of a shot now.
It amazes me that with basic mathematics and some simple ratio and proportion tools we can accurately predict the behavior of microscopic systems. It is truly awesome. Oh man what have you done!
Well... stoichiometry is an important tool that all chemists use, and I do not wish to diminish its importance, but if you really do look at particle interactions quantitatively the stoichiometry does not quite work out for a variety of reasons. One is that particles have to collide in order to react, and as a reaction proceeds there are less and less reactants available to collide, and so the reaction often gets slower and slower to the point where you cannot reach the stoichiometric end point. Also, it is quite dfficult to have optimal reaction conditions, such as 100% pure reactants, or optimal temperature & pressure. With small amounts of contaminants you may get what are called side reactions, which are reactions that are not the reaction of interest, and the reactants themselves can often react in ways that are different than the written equation. However stoichiometry is still the best predictor of the quantitative outcome, and it gives scientists and chemical companies a target for optimizing their reaction, and there are many other uses of the values calculated.
Taking Chem I in a 5-week course was a bad idea. Taking it with a 70+ year old instructor who's age is starting to show and who doesn't understand why his students can't understand his lessons is a bit worse. Don't get me wrong, my instructor is a super nice guy who cracks the most hilarious jokes and he's willing to stay after class to help you out, but his teaching style is all over the place and he doesn't understand the most basic questions you have about your problem. And of all of the lessons we've had these past 5 weeks (my final exam first thing tomorrow morning), stoichoimetry was the hardest for me to wrap my head around. Until I watched this video.... Thank you, thank you, THANK YOU for making this video four years ago! The "map" has been the BEST way for me to understand what goes where. I just wish I had found this video a hell of a lot quicker. It would have reduced so much stress lol
Thank you so much, the way my teacher presented it was overwhelming without much logical explanation of what she was even doing, but the way you formatted the mass to mass conversion process was concise and easy to understand.
couldn't be explained more simple than this, this is far the best video on Stoichiometry that you can browse, thanks for sharing your knowledge and uploading !!
i have taken 2 semester of chem and this stoichiometry thing never made sense, watched lot of videos which didnt help as such till i came across this one LIFE SAVER ON THIS TOPIC. GOD BLESS I WILL SAVE AND SUBSCRIBE TO THE CHANNEL. AGAIN THANK YOU FOR TAKING YOUR TIME TO EXPLAIN THIS.
I have realized chem is not for me, but I need to pass this class. This video actually explained what it even was. I learned more here than I have in like 4 lectures. Thank you, internet person.
I know this video has been up for a while, but you've no idea how much this has helped! I've a chemistry exam this week and could not get my head around this area. Thank you! x
I have a test tomorrow and the first 4 minutes of this video explained the simple stoichiometric concepts better than any lecture I have had so far. Thank you, you earned a sub.
This video seriously made my life so much easier, I have my unit test tomorrow for chem and you made stoichiometry so much more easier and less complicated than my professor. I actually feel confident in doing these problems now. The flowchart at the end is such an awesome tool to have. Thank you so much.
Saved my life. Chapter test tomorrow. Trying to learn this over the entire weekend to no avail: until this video at 11 at night before my test. Thank you sir. You're a god.
THANK YOU SO MUCH! I have a chemistry final tomorrow and after seeing this video of stoichiometry which i ad no idea how to do, i am bing watching your videos! YOU ARE MY SAVIOR!!!
Thank you very much: this was much much easier than Khan Academy’s explanation. They are both the same, but yours was much easier to follow. This was exactly what my grade 11 Chem teacher (God bless her) showed me: ALWAYS go by your units: you will never go wrong!

With small amounts of contaminants you may get what are called side reactions, which are reactions that are not the reaction of interest, and the reactants themselves can often react in ways that are different than the written equation. However stoichiometry is still the best predictor of the quantitative outcome, and it gives scientists and chemical companies a target for optimizing their reaction, and there are many other uses of the values calculated.
Your stoich map is so damn useful thank you!
I can not understate how helpful this video was for me. I took chemistry I two years ago and I am now taking chem II, and this is fantastic!!
You are a god.
He's more than a god
Taking Chem I in a 5-week course was a bad idea. Taking it with a 70+ year old instructor who's age is starting to show and who doesn't understand why his students can't understand his lessons is a bit worse. Don't get me wrong, my instructor is a super nice guy who cracks the most hilarious jokes and he's willing to stay after class to help you out, but his teaching style is all over the place and he doesn't understand the most basic questions you have about your problem.
And of all of the lessons we've had these past 5 weeks (my final exam first thing tomorrow morning), stoichoimetry was the hardest for me to wrap my head around. Until I watched this video....
Thank you, thank you, THANK YOU for making this video four years ago! The "map" has been the BEST way for me to understand what goes where. I just wish I had found this video a hell of a lot quicker. It would have reduced so much stress lol
This is beautiful
Thank you so much, the way my teacher presented it was overwhelming without much logical explanation of what she was even doing, but the way you formatted the mass to mass conversion process was concise and easy to understand.
thumbs up for Dvars!!!!
your so queer
Thanks a LOT! You just summed up 2 years of stoichiometry in about 10 minutes.. That helped a lot Thank-you once again.
I've never understood chemistry more 😭
👇If you agree
I wish I would have had this video a month ago. I have learned more by watching this video 10 times than I did the entire semester in chemistry.
hella heart eyes for you
couldn't be explained more simple than this, this is far the best video on Stoichiometry that you can browse, thanks for sharing your knowledge and uploading !!
You're welcome!
You teach my my school
THANK YOU! I struggled with this and just watched your video and it is like a switch flipped! Pretty sure you have saved my next exam grade!
You're welcome!
1/4 through AP chem and I'm here.... I'm an idiot
We're doing this in Chemistry Honors, I'm scared as to what AP Chem would be like...
you guys aren't doing so bad. I'm in college.
How do you make base chem harder?
@@devcentral7896 Doing harder problems and learning it all in a shorter amount of time
i have taken 2 semester of chem and this stoichiometry thing never made sense, watched lot of videos which didnt help as such till i came across this one LIFE SAVER ON THIS TOPIC. GOD BLESS I WILL SAVE AND SUBSCRIBE TO THE CHANNEL. AGAIN THANK YOU FOR TAKING YOUR TIME TO EXPLAIN THIS.
You sound like Jesse pinkman's chubby friend from breaking bad
He does lol
Brandon Mayhew exactly😅
Thank you for explaining this better in 15 minutes than my teacher did in four 50 minute long classes
you are a god!
Holy shit, 10 years later and I still learned more in this video than I did in 3 months.
who still dont understand??
I do
I do
Same & my exam is tmrw
Me
I
This has helped me way more with Stoichiometry than 3 weeks of lectures in my Chem class! Thank you
I have realized chem is not for me, but I need to pass this class. This video actually explained what it even was. I learned more here than I have in like 4 lectures. Thank you, internet person.
Thanks. Internet person is happy you commented, in particular cuz you called me Internet Person, which I find very funny.
My teacher went through this in 2 nanoseconds, this video was a Godsend thanks a lot!
seeing the flowchart at the end made me realize how awesome this is. Its amazing that we can do these conversions so easily.
I know this video has been up for a while, but you've no idea how much this has helped! I've a chemistry exam this week and could not get my head around this area. Thank you! x
Well, not much going on in stoichiometry these days. It is pretty constant. Glad it helped!
What I didnt understand since I was in 10th grade (14 years ago), I understand it with your 15 minutes 33 seconds video!! Thanks a lot!!
one vid of 15 min,i understood EVERYTHING now 3 hours a week for 3 months already and nothing
have a test tmr,u saved my life
I wish TH-cam and your course existed when I was in college. I think I actually understand this topic now after 20 years.
I have a test tomorrow and the first 4 minutes of this video explained the simple stoichiometric concepts better than any lecture I have had so far. Thank you, you earned a sub.
this is the best tutorial i have ever seen in my whole student life..best video ..i understood stoichiometry for the 1st time seeing only once
I have been trying to make sense of Stoichiometry for almost 2 years. It all make sense now thank you
no matter how much old the video gets the teaching and explanation is always on the top tier
Thank You!
This video seriously made my life so much easier, I have my unit test tomorrow for chem and you made stoichiometry so much more easier and less complicated than my professor. I actually feel confident in doing these problems now. The flowchart at the end is such an awesome tool to have. Thank you so much.
Saved my life. Chapter test tomorrow. Trying to learn this over the entire weekend to no avail: until this video at 11 at night before my test. Thank you sir. You're a god.
OMG!! I finally understood the concept. Thanks a million,sir. I wasted 3 periods on this topic at school and understood NOTHING.👍👍 You are da best.
THANK YOU SO MUCH! I have a chemistry final tomorrow and after seeing this video of stoichiometry which i ad no idea how to do, i am bing watching your videos! YOU ARE MY SAVIOR!!!
THIS MAKES SOO MUCH MORE SENSE. Thank you sooo much. Why couldn't my teacher explain this to me this way?
Thank you very much: this was much much easier than Khan Academy’s explanation. They are both the same, but yours was much easier to follow. This was exactly what my grade 11 Chem teacher (God bless her) showed me: ALWAYS go by your units: you will never go wrong!
