<p>was the one with c02 forming greenhouse because it forms an acid TT or TT CE. I put TT because i didnt think acidity had to do with greenhouse effect…</p>
<p>If someone could remember the exact wording of the question it would really help.</p>
<p>CB would not be ambiguous with the question and answer choices. PV/T = PV/T is probably the most important equation in all of SAT 2 chem so they’d expect you to know it.</p>
<p>CO2 + H2O –> H2CO3, an acid but that doesn’t have to do with the greenhouse effect</p>
<p>H2O + H2S I don’t remember</p>
<p>I said TT too because the acidity of rain does not contribute to the greenhouse effect. It was something along the lines of “CO2 contributes to the greenhouse effect BECAUSE CO2 reacts with water to produce acid rain.” If you read it backwards, “CO2 reacts with water to produce acid rain, so CO2 contributes to the greenhouse effect,” the statements are not related.</p>
<p>anbody remember the coiffecient of h2o with the H2s compund was it 1 …</p>
<p>i think the coefficient for h2o was 1</p>
<p>The greenhouse effect was in the second part of the question, to clarify.</p>
<p>btw the ionic one was 2 i guessed it right though</p>
<p>Yeah, that question was definitely T,T. CO2 contributes to greenhouse effect, and can react with water to make H2CO3, but neither of those are related to one another.</p>
<p>^jamesford im pretty sure it was the first. but it doesnt matter TT either way</p>
<p>I think I got 800. I so happy that I just knocked over my chair.</p>
<p>For the TTCE question about NaCl in water, it was something along the lines of “NaCl dissolved in water lowers the freezing point of water BECAUSE NaCl has a greater formula mass than water.” What did other test-takers say?</p>
<p>TT…molar mass has nothing to do with freezing point. its just that solute added to a solution decreases the freezing point</p>
<p>NaCl does lower the FP of water, thats why they put salt on icy roads.
I dont think it has anything to do with the formula mass though.
TT</p>
<p>NaCl will lower the freezing point but that has nothing to do with molar mass. The second part did say that NaCl’s molar mass is greater than H2O’s, which is true.</p>
<p>T T</p>
<p>^bell curves its TT i think</p>
<p>Sorry, Im soo excited that I mistyped.</p>
<p>If i get 770-790 hopefully atleast 780 I’m gonna run around my house 20 times for no reason lol</p>
<p>bell curve what did you put for functions? The answer has been confirmed to be density since volume was held constant. I asked a few friends who are in ap chem</p>
<p>Great, I said TT too.</p>
<p>TTCE questions were much easier than I expected, and they were somewhat straightforward.</p>
<p>ya i also had tt for that question</p>
