i am just spitting out random answers i remember so we can compile later. i forget all the TrueFalseCE and number answers so if you guys remember them, please share!

feynman81591

ah i remember one of the TrueFalse ones. the one about isotopes was False True. the first part was about some proton changes but the second part was correct.

and the one about the Kinetic molecular theory with high temps and low pressure was a TTCE

which reminds me, copper forms brown gas with 15mol nitric acid, conclusion is that different mols can make different reactions...

Electrical charge

It does take more electricity = t
More mass = t

Ce= blank

feynman81591

agreed.

88 grams of CO2 product means you need two moles of CaCO3 or something.

how lenient/harsh is the curve usually?

feynman81591

nitrate ion concentration .01 so ph is 2?

feynman81591

nacl neutral salt so ph 7 in solution.
SO3 was the compound with the given percentages.
Mn 2+ oxidation state was in choices II and III.
nacl in water will neither decrease boiling point nor increase freezing point. it wont make the vapor pressure higher either. i said something to do with conducting electricity?

so, now i am essentially talking to myself. did so few people take the chem exam? usually these threads keep going for a while.

i know haha

I was just taking a break because I could come back later when things finally got going.

which they haven't.

3-4 wrong, 1 blank- still 800? i am assuming that much^ so far i have only gotten one wrong but i am sure i did worse than that. lol

How much do u need to get wrong to get about 760~770?
I already omitted 1 and I think I already missed about 3

stix2400

calm down people.

you can miss like 5 and get an 800.

probably like 10 for a 760

feynman81591

i am not sure. i wish i had a general version of the curve. in mcgrawhill books, 5 wrong is 790 but 10 wrong is still like 750-760. in barron's 8 wrong is an 800 and anywhere from 8-12 wrong is a 770-800. i think the 2nd one is clearly inflated (maybe bc the tests were hard) but i am hoping that the 1st score chart is an underestimation of the curve.

what sucks about subject tests is that they never release how many you get wrong so you can never know how well/badly you did to receive the score you did. my friend left 9 blank on math IIc and i guess he got the rest right, but most people say you need raw score of like 43 or 44, but he got an 800. so maybe it will be better than 4 questions wrong for 800...hopefully.

I'm basing my predictions on the collegeboard books curve.

Sure it's an old test, but it's probaby better than every other guess out there.

okay, if people are still there, can we try to have a quick 20 minute answer session?
