Official SAT Subject Test - Chemistry - June 2015

was condensation an answer?

they were different problems

does anyone know the question???

I don’t remember if they were different, but I remember getting -795

73 is 800?

What did they mean when they asked us for a function of temperature? Like an equation that has temperature in it?

Can someone make a raw score conversion table on a google doc from an 800 score up to a 600 score plz?

there was no condensation as an answer, stop asking

the question concerning the answer that wasn’t a function of temperature was density…

can anyone answer me

the question bout being put in water forms an acid solution was it NaCl

i thought density is P*MM/RT

@rawritsjun I believe it was heat of reaction for CH4 + 2 O2 -> 2H2O + CO2; given delta Hf values: CH4 = -85 kJ/mol, H2O = -240 kJ/mol, and CO2 = -400 kJ/mol

the answer was total energy. temperature can change density

no im taking about the one with 795 as the answer

I think it’s density though, they said volume was kept constant. If volume is constant, the density would be constant regardless of whether or not you increase temperature because, Density(Mass/V)=P*MM/RT.

its -795 kJ for the combustion question

it can’t be positive since all combustion reactions are negative enthalpy

was the enthalpy in the paragraph or seperate?

Shoot I think I made a silly mistake and I got a raw score of 80… I’m really hoping for a generous curve crosses fingers.
