The first channel on chemistry that really makes sense not trying so hard to look smart like crash course channel or khan academy. You sir saved my life.
I just learned more about stoichiometric methods in ten minutes than I learned from six weeks of being in a class room. I wish I could fire my professor, I swear to god.
Wow after 2 years of college, and a bit of frustration with Chemistry, I find a free site on TH-cam that does a much better job of teaching and laying out the basics. I wish all teachers used this multi dimensional approach that blends so many different learning styles together. I have been stuck trying to teach myself Chemistry. There is something wrong with how our education system works. Thank you for your amazing, clear videos. PS Love the mind-map like concept maps.
Been helping me since 7th grade and I'm a junior. Wish he could just teach everyone in the US from their home instead of wasting our whole childhood in a jail of a school.
My son had to be pulled out of regular school and homeschooled as a junior because of immune system issues. Thanks very much, Mr. Anderson, for helping us through this! He and I are learning chemistry together. You do an excellent job.
This man has gotten me through every one of my science classes in high school and college. Don't understand something....? Don't waste your time with anything else just look up bozeman. My environmental science teacher in high school didn't teach anything herself, she just put up videos of him. What a godsend he is.
I am in AP Chem this year and have been searching all over youtube for some good videos on stoichiometry, and this has been the first one that has actually helped. Thanks!
Thank you for all the help. I received 5 for AP Bio all thanks to you, I really appreciate all the hard work that you've put into the videos. (regardless of past or present)
Very helpful! I subscribed to Bozeman Biology last year while taking AP Biology, and I was quite happy that you were doing AP Chemistry videos this year (correlating with my own progress). Hopefully you'll be making videos for AP Physics B next school year...
he's simulating the yield he would get if he actually did that reaction and measured the yield of CO2 but since he didn't do it, it's pretty much random
Around 3:14, he puts 18.02 as the molar mass of water. But wouldn't it be 36.04 because there are 2 moles of H20 in the balanced equation? I'm confused please help me.
The answer to the question you gave as 40 liters of H2O in response to your video in the 6th-minute 40th second and the answer in the 7th minute and 50th second is wrong! Because in standard conditions STP is also water liquid. and STP does not work for solids and liquids. STP only works for gases.
@5:57, how is oxygen the limiting reactant when it's less than the amount we were given? Isn't limiting reagent is where the product that's greater than what was given. I thought Methane would be the limited because its out of the amount that's give to us, It's 27.4 and we were given only ten grams of it. Can someone explain?
Consider the following : LiOH + HCL - > LiCl + H2O A) how many moles of HCL are there in 100 ml of a 1M solution B) what mass of LiOH would react with this quantity of HCL ( assume complete reaction and 100 % yield )? C) what mass of LiCl would be produced
Ok but I have a question. What if we have the molecules of something. How do we get from that to the moles to find the limiting reactant? Please help. I have a test in 2 days and I'm so confused on that.
Hi everyone! I'm currently doing Stoichiometry and was given this question: A compound consists of C, H and O only. When 10.68mg of this compound undergoes combustion 16.01mg CO2 and 4.37mg H2O are produced. The compounds molar mass is 176.1 g/mol. Determine the molecular formula of the substance. I can get part way through it but I was wondering if anyone here could help me out? Cheers
Dammit America! This is such a complicated way of doing it. I find that the equations we use are so much simpler and easier. m=nM where m=mass, n= number of moles and M= molar mass. And when doing gaseous equations, V=(n)(22.4). You can manipulate these equations depending on what they ask you to find by using normal mathematical principles for equations.

@@nathanreed2087 House arrest is better than actual jail/prison.
It's not as fun as it sounds...
well your wish came true
Didnt age well, friend
So this is your fault huh

Mr Andersen, you really helped me get through my first year of college. Year two and still watching. Thank you.
6 years later and you still helping people out God bless you omg !!!! finals this week !!
Thats it, im working at mcdonalds😂
but stoich is one of the easier things in chem?
@@RANDOMGUY2101 not for some people?
I'll just stay where I am 😂😂
@@RANDOMGUY2101 that is a very subjective statement good sir
My Chem teacher wasn't clear at all and I've looked at various TH-cam videos but still didn't understand stoichiometry. ..thank you so much
took me a while to find a video of a person who ACTUALLY does it the way my teacher wants BLESS

You just saved me at least an hour of reviewing powerpoints on titration within 1 minute
U r the best teacher Paul.Got special teaching skills.U interacts very well even through videos.how???????????????????????
In all,Paul Anderson is the master of analogy,making the difficult easy to understand.
One of your best videos, in all honesty
I miss learning this stuff. U were the peak of my hs experience 2013-2017
omg such a throwback this video helped me get an A in honors chem i miss stoich so much literally physics makes me cry
Love these videos. You have helped me so much in the past 2 semester. Thank you!!!!
Wow... that was actually EXTREMELY helpfully and easy to follow! Thank you so much :D
Thank you for all the help. I received 5 for AP Bio all thanks to you, I really appreciate all the hard work that you've put into the videos. (regardless of past or present)
Thank you for these videos. They are so good that I show them even in my French Immersion Chem class. Much appreciated. :)

This dude just summarized more concepts and made it make sense compared to my teacher who took two lectures to cover this.
Thank you! I was having a hard time making the connection from the way my teacher had done it, but you cleared it up for me!!! Off to my quiz!
Hahahaha thanks. I have no idea how I did. But I graduated so it probs wasn't so bad
You explained it better than my college professor did. Thank you!!!
happy teacher' day Mr . Anderson!!!
god thank you so so much!!! my teacher went over this in like 2 seconds and made it so hard to comprehend
Thank you, you broke it down so easily for me, thank you once again
Mr Anderson you're so good.💎
i'm in the 7th grade understanding this pretty well, you have a talent for teaching! thank you
When he finds the limiting reactant in 5:50, how do you know whether to use CO2 or H2O? Thanks.
It is because of your videos, that I may be getting a good grade in Chem 1A this year! Keep up the good work. :)
wwwwwwait....
where did 6.19g/ CO2 come from?
I know its the actual but where/how did he calculate it?
He just ...put it up there
he's simulating the yield he would get if he actually did that reaction and measured the yield of CO2
but since he didn't do it, it's pretty much random
Holy sh** you're the best. My test for stoichiometry is next week :D
Bahhh! Why didn't I find your videos sooner when I was high school chem!!! Oh well at least I can use your videos for college chem and bio hehe ;D
This is so helpful 🙌
HOW THE HELL U GET 55?!
@@yahyanouman7024 Legend! Cheers
@@yahyanouman7024 thank yoooooou
Took him 10 minutes to teach me what my teacher couldn’t in a month.
Excellent foundations explanation. Keep it up :))
What a great explanation
not a real fan of stoichiometry xD
where did 6.19 come from?
It is the actual yield. In a percent yield problem, it should be given to you.
thatawesomeperson27 Ok thanks
Where did you get the 6.19 from?
pretty much random - actual yield can be any percent of expected yield
Around 3:14, he puts 18.02 as the molar mass of water. But wouldn't it be 36.04 because there are 2 moles of H20 in the balanced equation? I'm confused please help me.
Josh Day it is just the molar mass of H2O not of 2H2O
Literally in the 1st 2 minutes this taught me what my boring ass teacher has failed to teach me for the past 3 weeks
thanks man i was stuck on this chapter before watching this video
The answer to the question you gave as 40 liters of H2O in response to your video in the 6th-minute 40th second and the answer in the 7th minute and 50th second is wrong! Because in standard conditions STP is also water liquid. and STP does not work for solids and liquids. STP only works for gases.
7:45 you could cross out the 22.4 from the numerator and denominator to make calculations quicker (must keep the L H2O at the end though)
@5:57, how is oxygen the limiting reactant when it's less than the amount we were given? Isn't limiting reagent is where the product that's greater than what was given.

Thankyou so much for posting this, I have a test on stoich tomorow! :) what luck...
you teach me more than my own teacher, he don't explain crap
you know who you are mr.H
thank u for saving my life
Thanks for the help! I understand a lot more now :)
8:51 what does soln mean?
You are a life saver!!! Chem 141 at MSU would be so much better if you were teaching it.
chemistry teacher stopped sending us work and now we are watching video to learn
i really like your videos keep it up :)
Consider the following :
LiOH + HCL - > LiCl + H2O
A) how many moles of HCL are there in 100 ml of a 1M solution
B) what mass of LiOH would react with this quantity of HCL ( assume complete reaction and 100 % yield )?
C) what mass of LiCl would be produced
I love you , you're so kinda for helping
thanks man! very helpful.
Ok but I have a question. What if we have the molecules of something. How do we get from that to the moles to find the limiting reactant? Please help. I have a test in 2 days and I'm so confused on that.
wonderful explanation
This helped a ton, thanks
Thank you so much! This is extremely helpful :-)
Finals this week
@John C Don’t remember what I got but now studying in college so good enough!
Thank youuuuuu! That was great!
I'm confused, in the Expected Product section, why is the yeild of H2O 55.2g? Isn't the formula mass of H2O, 18.02, * 2 = a yeild of 36.03g?
Can u convert from liters to grams using the bridge ??
thanks it really helps a lot
Very helpful.Thanks.
Seems easy and with more practice ill get better, Thanks!
hey how did he get 55.2 on the expected product? because when added together it equals 60.
+Sarah Mae Fernandez thank you lovely :)
omg so helpful !!! thank you so much
Very helpful! thank you:)
how did he get the actual yield?
Bozeman Science What happens when they don't give you the actual OR the predicted yield in a percent yield problem?
Where did he get 24.6g ?
Very helpful :)

+Luke Dives does that really work?
+Reese Maners yes it does.
My teacher says using 22.4 L for any gas is incorrect and we have to use a special equation
+romerobryan83 Liters is used for liquids though.
It's only correct at STP (0C and 1atm)
Excelente!
This questionnis for my exam and I cannot figure it out could someone help me please
Thank you!!!!
I FUCKING LOVE STOCIOMETRY
thank you
7:45 H2O's not a gasand does not follow the gas law.
The New Patriot Water has three forms, bro. Liquid, gas, and solid. XD
ha, once you learn this stuff. the actual hard stuff comes later!
i just dont get how you got 20.4 from 20? 😭
jesus that one diagram saved me hours
I'm curious to where carbon monoxide comes in? I thought all carbon based fuels created CO when reacting with oxygen?
