Introduction to Limiting Reactant and Excess Reactant
ฝัง
- เผยแพร่เมื่อ 15 ก.ย. 2015
- Limiting reactant is also called limiting reagent. The limiting reactant or limiting reagent is the first reactant to get used up in a chemical reaction. Once the limiting reactant or limiting reagent gets used up, the reaction has to stop and cannot continue. After the limiting reactant or limiting reagent is used up and the reaction stops, there is extra of the other reactants left over. Those are called the excess reactants. In this video, we'll first learn about limiting reactant and limiting reagent by comparing chemical reactions to cooking recipes. We'll look at how to calculate limiting reactant and limiting reagent using cooking ingredients, and then looking at an actual stoichiometry problem,

My chemistry teacher has a PhD and has taught for 20 years, but he can't top your cheeseburger method man.
My professor also had a PhD and studied at MIT and he was one of the WORST teachers I've had (I'm not joking...). That comes to show that no matter how much academic preparation you have, teaching is something that not everybody knows how to do. This guy right here is one of the best at what he does, without a doubt.

Anas Diab fr man mine is from rice university yet this guy still explains it better
🤣🤣🤣🤣🤣
Tyler also has a PhD. Lol
The reason this guy is so good is because he does not assume you know anything before the lesson. Most teachers assume students have prior knowledge on topics and that all kids are the same. This leads to kids no understanding how a teacher did a certain step when teaching. This eventually leads to a snowballing effect, as without that step the rest of the problem does not make sense. I really cant thank you enough for these videos as they have helped me a ton. I'm here studying before my chem final and I know I am more prepared after watching these videos.
Thissss
Chemistry Teacher: Recites definition of Limiting Reactant
me: uuhhhh, I don''t quite follow
Tyler, in the most soothing voice: *c* *h* *e* *e* *s* *e* *b* *u* *r* *g* *e* *r*
me: Ah, I gotchu
Ur right bro
All hail tyler the saviour 😂🤣😅
beese churger
Tyler Dewitt should get a Nobel peace prize for doing this fantastic public service. This is without doubt, the very best set of chemistry lessons, with the "most effective method", and with the simplest tools imaginable, just a piece of white paper, a marker, and infinite patience of someone who understands, and empathizes with struggling students. I'm ecstatic after many years of endless frustration trying to teach myself chemistry. It's been driving me bonkers. Tyler has broken through the barriers that plagued me. It's just a matter of pride for me to become fluent in all sciences, and Tyler has opened the doors to success for millions like me. It's his manner, his slow methodical calm demeanor, and repetition, without getting cocky running all over as if everyone gets it the first or second, or third time the way the instructor does.That's just not reality. Many great scientists, had to take years of chemistry, and repeat courses numerous times to meet the standard of their degree. It doesn't matter as much how difficult it is, or how long it takes you to get it, as long as you get it, before you hope for your degree. Thanks Tyler, you should get the Nobel, or at least chemistry teacher of the decade. For you young punks who want a hot girlfriend, a nice house, and a Beemer, $$$ Better pay attention.
Man this is one long comment 🤣
@@starmechgamer357 I love it tho
no, like genuinely though. seriously dude should get some major recognition, he really deserves it
YES I CONCUR!
agreed. taught me a lot
my mom saw me watching this guy talking about burgers and bread rolls, instead of studying for my finals.
Mom, it's not like that. it's chemistry, you just need to wait for it. it's really chemistry mom!
meshsone lmao
hahaha nice
had the same kind of problem
yes
same
Who else is here watching him for the test you have tomorrow
Edit: i dropped out of college
more like finishing homework and retake some test
Test in 2h lol
Mee 😭
yuurrr
finals :)
I’ve learned more chemistry in this 17minutes than I did in my 50minute college course
you are taught this in college. In India, we learn this in high school.
@@keshavnarang7719 I learned this in grade 11, and am now doing it again in University.
@@GhettoForLyfe exact same as me
@Adney Dong for me it depends we can either chose physics or chemistry in 10th grade, but in 11th grade we take the one we didnt take before
@Adney Dong We learn dis stuff in grade 9th here in india
His smile is the cutest thing I've ever seen. I love how much passion he has for teaching
The burger thing was genius
Thank you
Dude. I'm sorry if you're offended, but this is not important.
Tony Montana, you really need to pay attention. The picture clearly shows 1 complete bun.
Dr. DeWitt, thank you for posting these extremely helpful videos.
he was crystal clear as water lol
I wish all teachers would use simple explanations like you😩🙏thank you
is there is any organic chemistry videos of urs???
I wish I had a teacher like you
same
You do. His videos are your teacher
Yes bro me too I wish I had a teacher like him that explains it like him we just get "this is limiting and this is exest get ready we have a quizz next day"
I took honors chemistry my sophomore year of high school and I can’t thank you enough for these chemistry videos. Seriously, thank you. You were basically my real chemistry teacher.
I am an Indian and I will be giving the toughest medical exam of India and I was so worried about thus topic because it' one of the most asked one but let me tell you something man, you made this complex thing SOOOOOO easy which my teachers and many teachers on TH-cam could not do.
Great job man, great job
🙏🙏🙏🙏
did you sit for NEET?
Genius, dude you have a gift for teaching
honestly better than Khan Academy lesson
totally agree! Sal tends to rush over things and not go into details or reasoning as to why he gets the answers he does haha
Kayla V I love some of the Khan Academy vídeos but I hate when he rushes through things and doesn’t take the time to break down and explain. I also hate when he repeats his sentences over and over again..
Mario Padilla haha ya in case of stoichiometry
They r same u sucker....
Mario Padilla true that
Honestly, the way he taught wAs amazing!! Plus why are all the comments from like 3 years ago is nobody doing chem these days?
I'm as surprised as you are
I'm actually studying chemistry
Thank you so much... you're the reason I'm passing Chemistry. Is there any way to donate to your cause? Seriously, you're one of the best Chemistry teachers. I have struggled in this subject for a while and all of my professors have been ZERO help! I wish there were more Chemistry educators out there that truly cared about teaching like you do.
pretty sure you can use the Super Thanks feature which basically donates an amount you pick to him! It’s next to the download option if you’re curious
I'm here for most of everyone else's reason. My teacher didn't explain it correctly to the class. This video helped me understand completely! Thanks!
RIGHT!!
Lol my teacher sent us here
he was so proud of himself with his cooking analogy hahah
Yeah, but didn't you think it was good?
I thought it was great :D
+Tyler DeWitt Hah, I'm currently tutoring this topic and was trying to come up with a cooking analogy but just ended up fumbling and doing something else. I hope you don't mind if I use this to help my students!
you can't even make an example
He deserves to be proud, not because of example but because of the legacy he has created- Surely the best channel for chemistry and for teaching i give him 10/10.
Cheap bitches like you think there's pride in small things. Look yourself, you probably think that profile picture looks great but all are judging you as a show-off ...
This guy took chemistry to more simplified dimension 😊👏🙌
Many people will always say
“my chemistry teacher”
“My chemistry teacher”
Don’t blame your chemistry teacher I mean, let’s thank everyone one of them because they let us search for a better way to understand the concepts they are trying to teach us to understand
And that is how this guy saved my life in chemistry!!! 😅
Those cheeseburger jump-cuts tho
+Portsmouth School of Education I know, right?
Epic, even 2 years later
+Portsmouth School of Education "SHOOU-!!"
@@bigbangrasengan364 i find u
That was too smooth
This guy getting me through college. I love him.
Nicholas Strick your learning this in college WTF I'm in highschool and learning this
How was college then? Got good grades?
What college?
@@ofcourse4189 I'm in 7th grade and learning this.
@@spacegamer3836 yh it sucks
This is what teaching should be, some teachers love to over complicate things, making it hard to understand, but you make the explanation so simple and logical, these videos are awesome
“The ability to simplify means to eliminate the unnecessary so that the necessary may speak.” this video has no excess reactant that can give me a headache, amazing
this guy... this guy is good.
Better then Khanacademy honestly! Your videos are well thought out and just overall BETTER!
khanacademy made me fail my mocks xD
Khan Academy
The cooler Khan Academy
"The definition of genius is taking the complex and making it simple." - Albert Einstein.
You are definitely that one.
I truly hope you see this comment and all these other wonderful comments you completely deserve. You teach, with extreme enthusiasm and passion, a subject that is exceedingly stressful to a lot of people; One in which can even stand in the way of a lot of peoples dreams. You help build the bridge where these people can not only pass but sincerely learn the "how and why's" of the chemistry world. I'm sure you understand how much you help people of all backgrounds, but I just want to reiterate that, just incase someone hasn't told you in a while. Everything from Gen Ed, to people like me who are doing a career change into an entirely different world, from criminal justice to science (cop to nurse) are being helped and guided by the likes of you...and for me personally, not only are you videos helpful, they are fun to watch due to them being full of life and passion, not soulless and regurgitated. So, thank you. Truly.
My teacher was trying to explain this from 4 days, but I didn't understand a thing she told. You explained everything in just 16 minutes 57 seconds. I wish I had a teacher like you. Thank You! Thank You! Thank you so much! I wish god would create 1000's of Tyler DeWitts and send them to replace all the chem teachers in every single school around the world.
They could produce a Tyler DeWitt robot I guess and have em teach in schools
same
I wish all teachers could explain things as clearly as you.
I understand better about this concept in just 17 minutes (taught by you ) than my 1 hour 25 minutes Class of chemistry, My teacher just confused me , I like your videos , Love from India ❤❤❤❤
Hey Tyler, imma give you a shout out one day when i collect my world"s best chemist award or something of the sort i promise. Thanks man appreciate it a lot.
you seriously have a gift in teaching. Thank you!
but i can still make grilled cheese
Harvard wants to know your location
LOL@@noaharons6177
Wise guy
Okay ik this was from 3 yrs ago but I said the exact same thing
well, if Its still called grilled cheese with a bun and cheese
Sir, this lesson is a master piece in teaching and presentation! You (and the cheeseburgers) are why Internet exists! Thank you so much in making learning Chemistry fun!
This man has taught me better and more in-depth than my teacher with a pHD has taught me in an exceedingly less amount of time.
I gotta say, you are the best chemistry teacher i have ever came across. from high school to university, I always thought chemistry was challenging, but ever since I started watching your videos, I realized how easy and interesting this subject is. You make it fun and simple to understand. thank you very much Mr Tyler
So much better than Academy's video
I teach high school chemistry and I love the cheeseburger analogy. I am showing your video today to my students. Thank you!
In 2 minute I understood more than 4 classes of chemistry lessons in my school and book wow than u so much
I love this guy ! his timing is perfect ! I just learned this today !
y'all can stuff all the excess cheeses in my burger
lmao armies are everywhere. Hope you're surviving chem!
ARMY REPRESENT! XD
I’m tryna study chem and I find an army why are we everywhere sgjfh
Hahaha right 😂😂
reading this and seeing your jimin dp makes me laugh
My chem Professors, all of them, can not teach. They go over this stuff sooo fast and pile concept after concept upon you in each lecture. They challenge but not teach. Between $300 dollar text book and a Professor with multiple advanced degrees, I have to go to TH-cam to learn what I need to pass class. It’s ridiculous, but I’m glad people like you are here to help. Thanks
Who here has a chemistry test tomorrow. 😅I’m gonna fail
Tomorrow I have the test
ur cooked
my final is in less than one hour
Watched some of your videos all in one day!!! Passed my General Chemistry I test with ease!!! Thank you!!
I love you man. You make life seem so simple.
You explained better in 15mins what my teachers couldn't in 1 year. I'm gonna go cry now because I finally understood this topic. Thank you :)
I remember my professor used the hamburger analogy to explain limiting and excess reactant lol. and we had to make a smiley face on our answer to indicate the excess and a sad face if we found the limiting.
When he says he wants to make learning science fun,he really means it.
This guy has my heart. Life saver for everything. I have to pause because of how mind blowing it is to feel the concepts finally click together in my head after watching his videos
My teacher spent 2 weeks explaining this and in 16 minutes I finally understand thank u so much !🙌
Get this guy to 1 mil......... he’s a genius
Tyler De Witt I can't thank you enough for making me understand the limiting reactant concept
I am stuck at home with E-learning thanks to the COVID-19 pandemic. My teacher is not here to help me through this. You are truly my hero. Thank you so much!
The amount of time and energy that went into this video is incredible. Thank you so much for doing what you do.
You understand every student's perspective and teach accordingly; you are truly amazing; keep up with the good work!
All these videos from you, crash course and other channels have helped me understand concepts i was confused with and helped me get ahead in terms of content and pace and I'm really glad there are people out there who do this because i find these videos a bit like extension and not only are they clear and understandable, but they are in-depth to a point that you can't necessarily find from your teacher or websites (for me reading isnt enough). I don't know whether I'll continue chemistry in the future, but at least I know that if I do there'll be content like this that will always be here to guide me :)
By far you are one of the best Chemistry instructors I have ever seen in my life!! Thank you so much!!!!
I have no words...i dont know how you can teach so well😢😭.... i understand each and every point
Tyler DeWitt, you are the fucking man! I am only in the beginner chemistry steps but I wanted to make sure you see my message.
You have explained the concept in a really interesting way that is very easy to remember. Thank you!
His videos seriously are a life saver!! He simplifies everything so it's easier to understand.
You’re a lifesaver man our chemistry teacher barely attends classes and we have exams in a week so thank goodness I stumbled on this video!!
This is an AMAZING teacher! His methodology is so clear, explaining step by step, with so much patience, ease, and sweetness. He has truly made a significant contribution in teaching Chemistry. Thanks a million for creating these awesome video lessons!!!
Here the night before my test, I didn’t listen to my Science teacher for the whole week. Wish me luck.
Update: Took my final exam and got a 48/50 😃
good luck
gl well I hope you did well my guy
Best video of explaining limiting reactant! The cheeseburger and bread rolls just make it so much easier to understand, thank you so much!!
This guy is the best teacher in the world. God bless him. Helping me pass chemistry haha idk how I'd pass without him
You really deserve alot of honors , cutting each piece and thinking planning each step for an video is really a very tough work , requires alot of patience . Thinking such ideas to relate Chemistry to real life is not so easy, but you invested so much time in it , hats off to you . Good job . Keep up the good work. S
I'm watching this masterpiece after 7 years after this uploaded
I just love the way this young man explains the way to tackle chemistry .... I have learned more from him, than any other science teacher .
Where's this man's crown👑👑👑???? This guy's a life saver, thanks👌👌👌.
I love this guy! You should be the national Chem. teacher.
Give this man a nobel prize, this was so helpfull
Love it man. Been teaching this stuff for 3 years and this whole virtual thing makes your work exceedingly helpful.
Exam in 3 days U're a life saver. 17min video topping a term's lesson. U R AMAZING
Me : I’m gonna fail for tomorrow’s test !!!
( After watching this video )
Me : Well, that was easy !!
Cheeses burgers, bread rolls.. and moles !!!
When you were making cheeseburgers I was waiting for you to make the ULTIMATE GRILLED CHEESE with 6 pieces of cheese.
Ya know, there's just something awesome about watching this guy teach Chemistry. Not only does he dumb it down for us, but he's like nice about it and not condescending. I almost feel comforted dude.
I am watching this video after eight years. Thank you very much. Your method makes science fun and simple ,when you take science in an enjoyable way, you will see its magic.💗
You truly are a genius and a very helpful one at that! I tutor my classmates, so the more I watch you, the easier it is for me to share my knowledge with others. Thank you so much!!!
How’s it going
the way he explained is amazing...
I wish I had a teacher like him✍👌💕
Again, thanks so much for this! I passed my long examination last month because of him and we will be having midterms examination for the next two weeks! You're a life saver, really!! He's even better than my chem engineer teacher lol
You're the best. I'm from Peru and I dont know Spanish youtube teachers. Luckily I know some english and I found your class. Thank you.
Honestly, you teach me better than my chemistry teacher who tries to explain this throughout 4 classes lmao
Just wanna say another way to find the limiting reactant. Find the number moles for both of the compounds, then divide their moles by their coefficient, then the lowest is the limiting reactant.
that is simple
Your videos are what is getting me through chemistry. I can not tell you how many of your videos I have watched. They are very descriptive, I am able to understand thing better.
You are a fantastic, wonderful tutor, and human being. Thank you for all your patient help.
Great video! You explained it better than my prof! Thank you ❤️
This video was helpful Thanks Tyler KEEP UP THE KNOWLEDGE :D
You have no idea how many lives you save everytime you come up with such beautiful explanations.
Those definitions make much more sense now....u r the best teacher....god bless u man
I spend more time watching your vids than Netflix
I love this man 🙌🏼🙌🏼 thanks for the videos!!
I hope all teachers are just like you. You teach with a very simple method. Deserves all respect 👏👏
i learnt everything in mins thanks to youu..........you are the best..............i think indian private school teachers who spend so many days and periods should learn how to comunicate and teach...my teacher has a book opened up and if her notes are taken away shell struggle a lot
You are a great explainer, good sir!
can you make a video on drawing the lewis structure and also resonance and also molecular shapes? you're so good! love watching your videos!!
You always make things RIDICULOUSLY simple! 🙏
Well, you are still my favorite chemistry sir ever on TH-cam. Thank you soo much sir
When people master on something the love that’s the result! ❤️ That was phenomenal thank u !! I would love to see your videos even if i dont need them ! I have a quiz tomorrow and i was really struggling with this part but now I even love chemistry 😂❤️ thank u soooo much & we will be waiting your videos on pins and needles 🌸😋
