How much heat gets released or absorbed in a chemical reaction? We'll learn how to calculate this. We will use molar mass and conversion factors to figure out the enthalpy change in exothermic and endothermic reactions, which are represented by thermochemical equations.

Why don't we multiply the negative number??
Saved my butt, dude. Have a test today and I basically became an expert on this overnight because of you. My teacher isn't particularly bad, in fact he's pretty good but I'm taking summer courses and those are always rushed and go by extremely fast. You're a lifesaver.

Please help me how to perform calculations on the rate of chemical reaction
You're right, I just forgot to add a negative sign. Sorry about that.
You da best man!!! Why you are not making videos anymore? You're 100x better than my chemistry teacher

The best chemistry teacher in the world. Uses visual and audio tools so so well. Explains chemistry in simple layman terms. Amazing!!
a great question! in an exothermic reaction, the heat would be consider a product. because products are things that get made by a reaction, and here heat is getting made.

agent475816 How can someone 'try look smart' if they 'dumb it down to a 3rd grade level'? And if you're so well accomplished why exactly are you watching this video? it's clearly aimed at people who don't understand, so if you "know all this stuff" why are you watching?

agent475816 Is that not the point of the video? for people who don't know much? i don't understand why someone who understands this would be watching tutorials on it....
Dude you just saved my life ! I have tried tutors on campus but they all sound like Charlie Brown's teacher...whawha wa wha wha waaa lol, and my teacher has a funny way of telling you to figure it out yourself when you ask him questions.... I bet I wont be getting another C on these dang quizzes! Thank you for the videos Tyler!
LIKE TIMES A MILLION! I'm a pre-nursing major in college, and we covered this concept in General Chemistry 1 today and I was SO lost until I found your video! Thank you SO much! Keep the videos coming!!
8 years since you posted this and it still saved my life, thank you
You are literally everybody’s grade saviour. You deserve so much more views because your videos explain chemistry so meticulously, and I really hope more people would be exposed to your passion for chem. Thank you so much, please never stop educating and inspiring people 💙
It's amazing how in a few minutes you can make something that a teacher has been trying to teach for a week so easy to understand..
I would be failing chemistry without you. You make it so much easier to understand everything because you go step by step and describe everything your doing. Please keep making these videos, and I also saw you Ted talk a while ago and completely agreed with everything you were saying. Keep up the good work!
You're amazing!! I've been having the most difficult time with Chemistry and you are helping soo much. Thanks for the videos, really appreciate it
he is a naturally patient guy and his occasional smiles boosts us to keep going great job tyler
Man i always give other "youtubers" a shot but they never make it as simple as you man. You are GREATLY appreciated my good sir
I love how he finds the most simple ways to solve problems instead of doing the whole mole conversion table this makes more sense to me thank you so much Mr.DeWitt and god bless you!!!
I really like the way you teach, go over the problem and then explain what you just did. I really absorbed everything you tried to tell the audience. There needs to be more professors like you. Thank you.
HOW are you able to make chemistry as easy to understand as an episode of Sesame Street? Thanks you!

Jarrod Kearney I find sesame street harder to understand.
Your name is spoken with the utmost respect by numerous students throughout my chemistry class.
This man has fostered an enjoyment in Chemistry, something I thought I would never experience. Thank you!
9 years later still your videos are the best. Thanks
I have a quiz on thermochemistry today, and a final on Friday. This guy is very good at teaching this material. I would have paid money for him to teach me the chemistry I needed to learn to pass this class.
This was so great. Everything was so organized and I loved how you put the conversions on those notecards so you can show how you can choose one or the other. Thank you so much!
I think i'll pass my final exam now you are a life saver man. Thanks.
this guy is clutch. my chemistry teacher explains things in a minute and talks at warp speed and expects us to retain everything. after the lessons, im gonna come straight here .
whenever i have an upcoming chemistry test, this guy is the go-to guy
finally! i've watched so many videos on this and you're the first one that actually explains the equation. THANK YOU!
I have to say Tyler, your Vids are great. I particularly enjoy not waiting for you to write things down (you have it all set and ready to go on cards). Seriously, one of the finer aspects of your tutorials!
Tyler honey you have saved my life with these videos. so clear, leaves nothing unexplained,easy to follow love it! why cant chem teachers be this clear!!!!!!!!
You have no idea how helpful these vides are! I owe you my life lol. Thanks for helping me through midterms yo!
You are the best teacher ever.. i wished all teachers were like u
You are the best at explaining chemistry on youtube
Absolute CHEMISTRY SAVIOUR!!!!!! Your tutorials decode all the confusion instilled by smug Chemistry teachers-absolute brilliance! Many thanks...again!
This is the first bit of chemistry I've understood in 4 months. thank you.
12 years later and its still useful
You're literally the only person that makes sense of chemistry
You make this so clear I got a A+ on my chemistry test because of your molarity video I hope I'll get a A on my final!
Dude you are legend and so much more relate-able than these older professors. Thank you so much Tyler!
Let me first say that you are the only reason I haven't dropped out of my chemistry class. Also, I would like to say that you truly have a special gift for teaching; you are the only person who explains things in a way that makes sense! Lastly, I would happily pay a monthly subscription to have access to all of your videos (*hint hint PLEASE MAKE MORE). Anyway, I just wanted to say that you're the best and thank you for all you do. (:
I never leave comments,... but you TRULY make chemistry easier for me. THANK YOU TYLER!!!! After this I will complete my degree. You explain things so well. Best explanations I have come across from class, other videos on youtube, and even with a Tutor!
Your videos have been saving me through this summer chemistry class. You're so much better at explaining things than my professor thank you
Thank you Dr. Tyler! I’m beyond thankful for your videos! I’m a pre-med student and my professors are not the best, so most of the time I need to relay on the internet to help me, your videos have been so so so so helpful. The most hard thing for me to understand was Enthalpy, I watched your other video explaining endothermic and exothermic reactions and it saved my live. I don’t know why professors like to make everything seem hard. I wouldn’t be able to tell you how thankful I am to you and your videos, your teaching is so fun, it makes the subject so interesting and I always want to learn more. Thank you so so much ❤️
Wow ! Just amazing..I never learned chemistry so easily in less than 15 minutes. You're the best man. Thank you. 🙆😇
My final exam is tomorrow, Friday. I've been living and breathing this subject for weeks, no months. If not for you Tyler, I would have had to drop the class and not graduate this May! Thank you so much for everything!!!!!
The quality of your videos are phenomenal. Thanks a lot.
You are the best in chemistry! Please teach higher level organic chemistry stuff! I really need it for next semester! Please I depend on you to save my gpa

Try checking out Leah4Sci.com. Her videos are excellent and very clear, much like Tyler Dewitt but for Organic
I don't what I would do without you? You're awesome! All your videos!
I know that this has been said before, but really I owe you my thanks Mr. DeWitt! :D I have been struggling to understand Thermochemistry during my Chemistry course for more than a week and thanks to your brilliant explaination and examples it all finally clicked into place. Seriously you are a brilliant teacher and saved me from bombing miserably at a upcoming Chemistry exam. Best wishes!
Passion and smiling make your work effective man.Thank you for making chemistry easy.
Awesome video! This was explained better in 12 minutes than it was by my teacher in over a week!
You make this super simple, it's great when youre prepping for a final! Thanks a lot
You are better that most teachers. ✓✓✓
Thank you so much for this video, I didn't understand fully from my year 12 till I watched this video. Thanks again and may our good Lord help and bless you in what you are doing .❤❤
You're such a life saver! I wish you were teaching my Chem class.....the sad life of a community college student with bad professors..
You are a great teacher. Much better than a lot of other instructors. You explain very well. Thanks.
Thank you. My honors chemistry final is tomorrow. I'm sitting here cramming and your video helped a lot.
really one of the best chemistry videos on youtube, very simple (y)
Bless your channel for the quick review for chemistry you are pretty much saving my final grade
This was so helpful! My teacher makes it seem much harder than it actually is! I think I might actually do okay on the test tomorrow now :)
YOU ARE THE BEST CHEMISTRY TEACHER EVER! THANK YOU AND PLEASE KEEP MAKING MORE VIDEOS
We're having a test on this stuff tomorrow and since I've been out sick the past two days this video really helped me catch up and understand! thanks!
Tyler, thanks so much for your help! Your videos have been a great tool for me throughout my class. Chemistry is such a challenging subject for me and you really break things down and simplify the problems! I was working at these problems for hours last night and just couldn't grasp it, and now after watching your explanations, I have it down pat! Thanks again!
You literally know how to explain everything perfectly
This is actually pretty easy....easier than I thought. Great video as always
Exactly what I was looking for. Thank you so much!! I literally spent a solid hour crying because I could not understand this because my teacher felt the need to cater to the the smarter kids instead of teaching the dumb one, aka me.
THANK YOU SO MUCH! OMG I AM LITERALLY SCREAMING IN MY ROOM BECAUSE I ACTUALLY UNDERSTOOD CHEMISTRY! Just with ur 12 minutes video! THANK YOU SO MUCH!!!
It's amazing how little I learn in class and how much I learn from a 12 minute video.
oh my goodness, this video is for 11 years ago and still helping me
You are AMAZING!!i wish you were my professor in my Chem 1210 class! Thanks a bunch:)
best video on thermo, cuts to the point and has you learning by doing. Thank you !
these videos are saving me and my best friend's life! thanks so much for making these!!!
Thanks, you've helped out a ton of students with homework from everywhere. You help me out with almost every assignment and I want to thank you again for that! :)
Thank you so much! this is the one thing i didn't know for my final tomorrow, your my savior. Your also a very talented teacher, you earned my sub. good day sir.
i love the set up of your video. it is a glorious refresher for my college chem final!
thank you so much. I'm in AP chem with a poor teacher and always look for you to help me clear any rough spots.
He is a genius at simplifying complex issues. Thank you.
9yrs later wht wonder full teacher you made me to love chemistry
Can you do a video on reaction rates and chemical equilibrium please?
OMG, very very VERY VERY HELPFUL!!!!!!!! Sooo good! I have a chem test in a 2 weeks, and am trying to understand this. You went through it very slowly and it helped to clarify any questions I had! THANKYOUUUU :):)
Bro you just...I haven't any word for you I appreciate this things..
Prof is behind on lectures and exam is in just a few days. This helped me a ton, thank you.
Thank you Tyler! You have helped me so much!!! Online classes are hard since we don't have teachers in class. So you are technically mine! Thank you sir. Keep up the good work!!
Thank you for all these videos! You are seriously helping my grades!
So thankful for his clear and concise explanation of Chemistry! Slowly but surely, I am understanding the concept that will be on test Monday!!! Make more videos, please!!! You explain things in way that I can comprehend!!!
Dude you are the best teacher ever!!!! I get everything you explain. THANKS
Thank you so much, Tyler. I wish I had you for a Chem teacher, mine is very bad. Keep up the good work!!!
Better teacher than my professor, thank you so much.
you make chemistry look soo easy.realllly helpful stuff
I don't know why, but when Tyler explains it, it's clear as day. When my professor explains it, I just have question marks all over my forehead. 😂
I got -1,530 for the first part. Don't know how you could miss that.
If only i had you as my teacher! Ive got a final tomorrow, wish me luck. This helped!!
This man is the only reason I’m passing chem 😩👏
This man is so helpful and explains things so well
I really appreciate the method that you take when you explain things.
I just passed a chemistry test because of this video and i barely passed anything in chemistry prior. Thank you
You're a legend man! I swear. Major appreciation
