Ms. Maribel, from the bottom of my heart, thank you so much for your videos! Your lessons are so concise and easy to follow and not filled with jibber jabber (like a certain Hank Green... xD)

The struggle with chemistry is real! Especially online learning! This is my first time taking chemistry; I'm in college studying nursing. I was doing well until this and spent 2 days working through the last 2 problems on my homework and just couldn't grasp it. I wish I found this channel sooner, you've explained this in a way I can understand. I'm not feeling much less anxious and stressed about this topic. Subscribed!

Yours are the best chemistry question example explanation videos I’ve ever seen

@tbpion9460 Год назад

thanks a million!! you are the best at explaining and simplifying everything! I did really well on my chem exam thanks to you!

@brookejenkins2516 Год назад

I have been subscribed to your channel for a little while, and you are so helpful! I will be checking out these guides --- hopefully before this final! You're so great --- thank you sooooooooooo much!!!!

really helpful for me right now, thank you!

We tackled this in our class but I didn't get why the answer was positive even though the sign in enthalpy is negative. This was really helpful.

What book guide include this kind of thermochemical equations, and specific heat heat of fusion,vapozation, ?

@redengineer1753 2 года назад

So I have to know heat from other similar reaction in order to count it?

@tutstorial8474 4 года назад

can I ask how to solve this one? I really don't know how to this but since the topic is about combustion maybe you can help me on this. 😅 An engine used to pump water raises up 1000lb water 100ft. In doing this, 1 lb of fuel having a HEAT OF COMBUSTION 1000 Btu/lb was burned. What percentage of heat produced was transformed into useful work?
