October 2016 - SAT Chemistry

The answer was 6/Avogadro, which is 1x10^23

Im guessing the curves gonna be about 78-79 raw for 800.

I dont think 1*10^23 was the correct answer tho haha

But it is the correct answer -_-

Oh my bad. I thought u were saying avogadros number was the answer instead of 6/1.010^23. Yea i think 6/1.010^23 is right.

Was it not 6g? 6 moles of Hydrogen * (1g/mole)…

@Bruhwhatisthisscreenname 6/Avogadro is not 1.0x10^23… It’s a tiny #

6 g. Is what I got. But if there really was an answer choice of 6/1*10^23, I believe that should be the right answer…maybe. Lol i dont even remember a choice like that tho so

Guys… What was the answer for the rate of Diffusion of Helium and something? I wrote Helium is more.

Helium is faster than the other thing cuz its lighter

Cool, Thanks. What about that Q- Which Substance on heating Increases Mass? I was confused between Mg And CuSO4.5H2O

@ThugLife13 Mg, when a hydrate is heated it loses its water

What was the answer to the question about the energy level change that yielded the highest photon energy? Was it the same as the answer to an electron transferring to the ground state? And also, what was the answer to the one that required the greatest input on energy into the electron? Was it the one where the electron moved up the most levels?

The release of the most photon energy I beleive shouldve been the one where it dropped levels the most. Ground state was moving up on energy level since hydrogen ion is H+ i think. And u r correct on the one where the most enery is needed to move up a lot of levels.

Not sure if this was difficult… First time taking it and thinking about cancelling scores. Omitted 5 and guessing about 3-7 wrong on the ones i answered. Any thoughts?

How many TTCE’s?

And for the question about how much energy released was it -1670(something like that) or 8something or 4sometjong?

The number of hydrogen molecules is numb of moles of XAvogadro numb = number of molecules or atoms and the question asked for molecules

Molesxavogadro=num of molecules

atoms or molecules divided Avogadro = moles

@ CrimsonZa around 2 I guess
