I just wanted to say thank you so much for these videos! You’re the reason I was able to get through all my Aleks topics and you also helped me understand my chem 120 class this semester a lot better! ☺️🙌

Thank you for explaining that we don't have to worry about ALEKs wanting the answer in kJ while our answers are in kJ/mol lol. The whole reason I searched up this video was to find an explanation for that!

ALEKS is a tricky little bugger sometimes :)

what do I do if the problem gives me concentrations instead of pressures? help me roxi I love you

❤️ you can use concentration in place of the pressure

If the problem gives the concentrations of the reactants, but only grams of the product (with no Liter value), how do I solve for the Q if I don't know the molarity of the given product in grams?

Is the product a solid? If so, it’s left out of the calculation of Q. Only use (aq) and (g) to solve for Q, just like K.

@@RoxiHulet okay! so then since the product is solid, would the numerator to solve for Q, be one?

I noticed towards the ending you changed the signs after getting -11448 j/mol. Why is that? How come you didn’t just do (-32.8 kj/mol) + (-11.448 kj/mol)? I tried and got the wrong answer but i want to know why 🤣

hey, I watched the video and I don’t see the point where I changed a sign. Could you be a little more specific?
