you have taught me this in 21 minutes but my teacher couldn't teach me this properly in one hour. edit:3 years late but i got an A in gcse chemistry thanks to you😎
"To me, conversion factors don't make any sense at all." Finally, someone who is really good at this stuff while simultaneously agreeing with my opinions on the subject.
Tyler DeWitt you make Chemistry fun. My professor is so boring when he lectures. He makes the problems seam so complicated and only goes through them once and moves on.
At precisely 14:50 min mark, Tyler makes an error in calculation. The answer to the conversion of O2 to H2S is 6.2 (rounded) not 9.2. He quickly pushes foreword and finishes the conversion from O2 to SO2 with the correct answer. ;) He is a fantastic teacher. I just find that when a teacher doesn't acknowledge their errors, it can be very confusing to the pupil. :) Thank you for all the work that you do, Tyler!
@@davinaleyva9571 Me TOO! I totally rewinded and thought to look in comments to see if I was the only one that caught it. Glad it WAS an error and not something I misunderstood. LOVE This guy! He's a great great teacher!
You're still out here saving the lives of students whose professors don't slow down and let us know what and why they're teaching. You saved another one from this monster of Chemistry. Bravo sir!
seriously i was in lecture today for 2 hours and didnt learn SHIIIIIIIIT ive been watching this video for 2o minutes I UNDER FUCKING STAND MOLES... Thank you your the BEST !
Honestly I didn't understand a THING while I was learning this in class. UNTIL right now, it is so clear and easy now. HOW. your're amazing honestly lol
so sad how teachers that work in schools hate their jobs as well as kids yet an AMAZING person like you will take the time out of your life to help students learn basically for free. Thank you!
My Teacher was only teaching us the conversion factor way and I didn’t get it. But when you explained the recipe way, the lesson became WAY easier. Thank you!!!!
I don't know where do I start ;how do I give you my appreciation ,you aren't only solve the problem ,you also solve our brain problem ,by showing easy related things like recipes.
Thank you so much, my chemistry teacher dosent really understand the concept of "teaching" so i was very confused during class, and this helped me a lot
My teacher has been explaining this for a whole week now. I didn't understand anything because he was going so fast and didn't explain it like you did. I have a quiz tomorrow and I stumbled upon your video! You're a great teacher and this explained it to me perfectly. Thank you so much!
Utterly perfect .... I am an older Mom and your videos have been fantastic to teach me a subject I haven't looked at in 40 years so that I can teach my grade 11 son this stuff.. I now know chemistry inside out. You are a great teacher.
THIS IS THE ANSWER TO MY PRAYERS! I used to think chemistry was a breeze, then I encountered moles and stoichiometry. I thought I'd lost all hope but I found this video and I cannot express how grateful I am! I can now feel like the real life alchemist I once felt like :D (ya know, all the mixing and pouring and test tubes feel magical) Literally laughing with joy and eureka's in the middle of the night. Thank you!
As a chemistry teacher, Tyler's videos are on all my assignments as an additional support. Students miss, need to review outside of class, etc. These are the best videos for my general students. Thanks!
I am 25 years old taking chemistry for the first time for nursing school, it is the most difficult class I've ever taken. I want to cry after class each day, but I've been reviewing your videos after each lecture and concepts are slowly making sense for me. THANK YOU MAN
Your way of explanation is so cool. It seems as if I know everything when I see your videos but whenever I read textbooks or listen to my teacher's lecture I literally don't understand it. This topic seems to be so easy to me after seeing your videos. You make us learn and understand everything from the basics. You have seriously got a lot of patience. Thanks a lot. This has literally helped me a lot.
I am a high school chemistry teacher. I love using these videos to supplement my lessons. I like that Tyler shows "common sense" thinking and then shows the accepted math. In several videos, he states that teachers and textbooks "love" conversion factors. The reason for that is that conversion factors are the STANDARD. If you go to college, you will be expected to use conversion factors. You will look foolish if you don't know how to do it that way.
Your videos have got me through chemistry! I am now a peer tutor for the subject at my college. I create custom chemistry videos for my peers to help with specific problems.
I was gonna be screwed for my quiz tomorrow, after a week of class i still didnt get it but after a small 5 minutes of this video i feel like an expert. God bless. you are officially my dad
I sat through a 55 minute lecture and learned absolutely nothing I sat through a 20 minute video and learned everything on the topic! You are a hero to me!
Very helpful. I am taking gen chem 1 over the summer (kill me) and my professor never explained why she did the ratio they way she did. She just rights the two numbers and never the units so i had no idea what she was doing. Keep up the good work!
+vince gredo forget that they're called conversion factors, if you're good with basic mathematical ratio and proportion, then do exactly that, and things will get simpler.
I can't believe how easy you are making this. Can my tuition money go to you instead? WHY am I spending hours and hours in chemistry only for them to over-complicate everything??!?! i love u.
+James Garcia You both have the grit to keep at it. You will eventually get that aha moment where it will all come together. Trust me, been there, done that and had many headaches.
Thanks so much man. I've been using a bunch of these videos to save my grade. You are 100x better compared to my irl teachers, it really shows how much you care.
My chem teacher did'nt explain this well...she did not treat it as ratios...ive sat 2 hours for 2 times evry week in class not understanding a thing. Luckily there is you, making me FINALLY UNDERSTANDING HOW TO TAKLE THESE PROBLEMS...you made realise that its acctually ratios and this makes it easier. Thx alot!
Well teacher, I am watching this after 9 years of the day it was published. Still solid as rock. You are way more better than my chemistry teacher lol.
Ive literally never commented on a video in my 32 years of life. but thank you to this guy, who has taught me basically everything i know in chem. youre a hero
Thank you so much Tyler! Your teaching methods are brilliant and I've learned more watching your videos then I have anywhere else!! You are a chemistry student life saver.
Ive been studying this stuff for WEEKS now and have been pulling my hair out. I watched this video ONE TIME and got them all right!!! You are amazing sir.

Tyler, thank you for all you do. I have been passing all my tests because of your detailed explanation. You never disappoint :) It was a struggle for me, but not anymore!
I have watched several videos on chemistry and by far you are the best on this platform. Amazing instruction, great tone and pace. His videos are excellent to use in conjunction with class material.
Wow, this is amazing. You should seriously teach other subjects and cover everything in common core 2.0 and just post it. Every student in every school in common core 2.0 would be able to quickly look up your videos, and they would be instantly informed. This is literally black magic in its integrity. Amazing stuff. Please Please Please do this for math, history, trigonometry, etc.
I'm so incapable of paying attention to chemistry that I got distracted by the fact that he doesn't have a wedding ring and started thinking in my head "damn, I hope he finds someone soon" and "how can he be single? He seems like a nice guy"
Because a lot of schools don’t focus enough on hiring teachers that actually know how to teach, instead exclusively focusing on if they know the subject well enough What a lot of people fail to realize is that being good at something does not equal being able to teach it effectively whatsoever
I know if I had better teachers that would just teach us the formulas instead of being all vague and using over complicated word problems and trick questions I would be able to do math better I can actually solve it pretty fast when I’m actually told how to solve it I don’t even need the answer for that specific question
Finally somebody who can Truly EXPLAIN something!! This actually makes sense and I was struggling so much with other teachers and videos. Great teaching just amazing
@14:55 i think you made a mistake there also i did the one with the conversion and its 6.13333333333333(to the infinite) although technically they are both 6 moles but maybe i did something wrong?
YOU ARE MY HERO! I had literally no idea how to do this and was struggling in chemistry and then I found the videos you made and they have saved my grade and my love for science. You are the man!!!
Bro, I love it. He's over here talking about all this conversion factor stuff being too complicated. You're so correct. I missed the first day my teacher taught on this stuff and the fact that I wasn't there, had no explanation of what we were doing, and was in an accelerated class meant I was so lost. If my teacher had just showed us this, I would have realized how simple it actually was.
yeah.. wow.. I laughed so hard when you said conversion factors make no sense.. uhh THANK YOU! I have only been saying this my whole semester. I should tell the dean of the school to cut you a check and fire our horrible professor. When we ask her for help she acts irritated like we are bothering her. Just discouraging. Thanks again!!!
Thankyou so much! I couldn't understand stoichiometry all these years, I thought I was stupid but after your lessons I'm grabbing the concept behind it. you're a very good teacher
Like so many others have said, you are an amazing teacher! I have watched many other videos and have still been struggling. Thankfully I found your video because in 17 minutes my light bulb went off and the rest is history. THANK YOU!!!

Honestly tho lol
i ve been studying for three years now and only now i understood it
My teacher doesn't even know how to teach and relates everything to football...everyone hates him and that class.
Yoda RIGHT!
Football? Lol that's funny.
the dislikes are the teachers being jealous of his amazing skill of teaching!
Yes !!!!!! They are being jealous teachers hahahah
So true
Exactly
No its the students who dont know how to do these 😭

from highschool now to college he has helped me for 6 years.

How does he teach me more stuff in 10 minutes better than my chem teacher in over an hour?
