This helped me more than you know. Simple, Clear, Concise. Teachers should strive to master the skills you have. Unfortunately most teachers are overly concerned with students perception of themselves and complicate a simple subject trying to display themselves as smart.

Hi Chad, I just wanted you to know that I scored a 517 on my MCAT with a 131 on the chem/phys section. I 100% believe that it's due to your videos. They've been a great help. Thank you so much for all you do!

Hey Chad, when calculating the rate of change of NH3 can you explain why it’s 8 & not 6? Why wouldn’t we just divide 12 by the coefficient of NH3?

Are all states of species included in rate expressions? We know that solids and pure liquids are not included in the rate law for a reaction, but I'm not sure for rate expressions. Thank you!

Why does the concentration go down? How do we know? I get how we have to put ”-” sign to make the answer positive but I just don't get why the answer would be negative if we don't put ”-” sign.. Please help, my chem teacher at school isn't very helpful lol
