Re: Pizza Rolls REVIEW Session DOWNLOAD HERE

Does anyone know how we got the temperature for question 6 on pizza rolls? I have 304.55 from the review session but i'm not sure how we got it.

Mnemonic Devices

Hi,
Does anyone have any mnemonic devices for remembering which are extensive an which are intensive properties? Also one for remembering the state functions?

Thank you

Re: 4A.11

I'm doing this one right now and I think you only have to use the equation C = q / delta T

Re: Prep for Test 1

No I think that the values will be given, but we should be able to interpret and apply these values :)

Re: When to omit "x-term"

Hi! We omit the "x-term" when the equilibrium constant is extremely small. K must be < 10^-3, this is because the value is so small that even if we factor it into the calculation it will not affect the overall answer.

Re: Final Jitters

I would say to be mindful of your breathing. Our breath controls everything and sometimes when we're anxious we don't breathe as clearly. I find that slowing my inhales and exhales really helps me ground myself and remember that school is not the end all be all.

Re: Equilibrium Constant

Kc is used when the concentrations are given in the question, and Kp is used when the partial pressures are given in the question. For Kp, the given amounts typically have a unit in pressure (i.e. bar) which helps distinguish between the two.
