<p>molar mass is NOT affected by temperature. Density is strongly influenced by the temperature, especially in the cases of gases.</p>
<p>Mass was the answer of one</p>
<p>Anyone remember what number the test ended on? If it was not 70, I’m screwed…</p>
<p>Yes there were 70 lol, everyone confirm</p>
<p>Thank god…</p>
<p>why was it 2.5 mols excess Li?</p>
<p>i remember hte reaction was like
6Li + N2 → 2 LiN</p>
<p>the test definitely ended on number 70.
Also I believe these questions were not covered yet. There was a question where there was a 100mL solution of 0.1M HNO3 and it asked which statement was false? Was the correct answer something about phenolphthalein? Or was it 0.63 grams of HNO3 is in the solution. I was debating on this one because technically there are 0 grams of HNO3 since it dissociates completely. Or is my logic incorrect?</p>
<p>Also there was one where it asked the correct coefficient of POCl3. I got 10 I think.</p>
<p>It was definitely the one about turning pink because that indicator only turns pink in basic solution. I got 10 for POCl as well.</p>
<p>seriously that Li2N question didn’t make sense</p>
<p>if you were given 3 moles of Li and 3 mols of N2 then the limiting reactant would be Li, making 1 mole of the product, and having no excess of reactants…</p>
<p>I dont think your balanced equation is correct. I dont remember the question either but I remember getting 2.5 moles N2 left</p>
<p>^ What I got.</p>
<p>Was the letter choice for the non polar bonding (Cl2) Choice C?</p>
<p>2.5 excess. 10 for POCl3. phenolphthalein turns pink in base and is clear in neutral and acid.</p>
<p>My hunch for the curve is </p>
<p>85 (perfect score) = 800
82 = 800
75 = 750
67 = 700
44 = 600 </p>
<p>Percentile Curves:
800 = 92nd
750 = 77th
700 = 61st
660 = 50th</p>
<p>May’s curve for the SAT Subject in Chemistry is traditionally harsh as many students tend to do well.</p>
<p>I left those lab equipment questions completely blank. The rest either I knew them or I didn’t. Hopefully I got at least above 700.</p>
<p>I remember a question when you combust a normal glucose with O2. What was the coefficient of O2? This question was so random…</p>
<p>@MyGoodLord 9.</p>
<p>what does a -3 look like?</p>
<p>@tjhsstKid21 790.</p>
<p>Banned, it was actually 6, the original carbon compound had 6 Oxygens in it, (18-6)/2</p>
<p>@ankitp4t3l I apologize; I stand corrected. One of the questions had an answer of 9 though. Yes, I do remember putting a 6 down as an answer for one of the balancing reactions - probably this one. All of the numbers are becoming a little fuzzy.</p>
