<p>annez ^Yes, AgCl2 is insoluble (it was NaCl with AgNO3)</p>
<p>sjsharks, the choice was AlO3, which cannot occur because of Oxygen’s oxidation state (-2)</p>
<p>how many can you get wrong to still get an 800? anyone know?</p>
<p>it’s AlO3 … on the test there wasn’t a 2</p>
<p>@ binghulu262, probably -4. Im hoping :D</p>
<p>AlO3 is impossible because Al has a charge of 3+ and O has a charge of 2- so the correct formula should be Al2O3</p>
<p>NOOOOOOOOOO WHY DIDNT I SEE THAT IT WAS AlO3, NOT Al2O3. CRAPPPP</p>
<p>on a scale of 1-10 (10 being the hardest) what would u guys rate the test?</p>
<p>Agcl is an insoluable white precipitate</p>
<p>i thought it was a 5/10. Not 2 bad. The lab questions were a little tricky</p>
<p>Anyone remember the one with the equilibrium expression?
I put 2.5x10-3</p>
<p>@harvard12, you are correct</p>
<p>I agree. I have a bad feeling about this test. I usually fly through all the first set of multiple choice questions, not so much this time. I’m registering for the June test just in case I don’t break 700.</p>
<p>what why would they put SiO2 on there too i was convinced the formula had to be Si2O3 -____-</p>
<p>on a scale of 1-10 (10 being the hardest) what would u guys rate the test?</p>
<p>SiO2 is a network solid… it’s correct</p>
<p>on a scale of 1-10, 1000
it was harder than barrons and i thought barrons was supposed to be harder than the test.</p>
<p>annez95, sio2 is a network covalent solid</p>
<p>it was also harder than ap chem prep i’ve been doing in school. sigh. life is so hard.</p>
<p>@sjsharks Oh thank everything holy</p>
<p>was 2.5 mole excess of LiN (some compound with Li and N) the answer to one of the long stoichiometry questions?</p>
