Thank you! My chem teacher only glazed over it, and expects us to learn this from the homework, but the explanation in the homework isn't very clear.

My Chemistry teacher speaks to him self and laughs at his own jokes instead of teaching,

[lROClKERS]

i wish you were my chemistry teacher cuz mine don't teach it right

[gppstudio]

u talk too much :)

[jankyjay253]

Thank you. My instructor tried explaining this, went way too advanced, and couldnt finish the problem half way through it... then he gave up and moved on to another topic. Glad I took it upon myself to utilize helpful videos like this to actually learn the material properly.

Does this work if you're given 3 enthalpy changes?

[FreemanVonDon]

@ShonieShanya Yes; like she said you may be given more; what may happen though is sometimes reactants may cancel eachother out

Just checking why this is different from the short cut answer.... - Based on the shortcut you showed in previous video -

delta H(total) = sum of delta H (pdt) - sum of delta H (rxt) = (-) 198 kJ - (-) 594 kJ = (+) 396 kJ

actually never mind she corrects it at 3:30  :)

[cook1e2]

when she multiplies by 2 at 1:36 to get 2S(s) + 2O(g) ... shouldn't it be 2O2(g)?

beautiful equation and woman
