<p>that rings a bell i think i put two as well… didnt they mention something about it being a redox reaction?</p>
<p>I really can’t remember, but maybe?? There was one about what is the coefficient of something in this redox reaction involving Pb but I remember nothing else about the question or what i put… hah very helpful I know!</p>
<p>crap was it molecules or atoms? I think it was molecules??</p>
<p>i am sure that 3 X 10^23 said molecules because i had the CO2 confused with H2 and that was the last problem i did and i read it about 20 times… so i think the answer is CO2</p>
<p>thank you vanillaextract! i’m so glad that you’re sure on that one, if i get any more wrong i might have to cancel my score.</p>
<p>I’m in the exact same boat as you, itsasmallworld</p>
<p>Yes, the answer is C02, it said 3 x 10^23 molecules which is half a mole. It said 22g C02 which is 1/2 mol CO2.</p>
<p>Thank God i put that lol, whew. I am so scared that someone is gonna come along and give me another wrong answer.</p>
<p>^yep 10 char</p>
<p>YESS. Thanks.</p>
<p>hah DAMN IT. I could have sworn it said atoms!! stupid rushing through test… what was that one about NaOH or sometthing? It was like…idk I don’t even remember</p>
<p>It HAS to be molecules! N2 is a molecule- not an atom!
(assuming we’re referring to the same question)</p>
<p>EDIT: Oh, wait. Nevermind. I know what you mean, now.</p>
<p>I don’t remember the NaOH QUESTION, but the correct answer was .1g. I’m pretty sure.</p>
<p>hmm LesOs both atoms and molecules make sense in the context, even though I believe VanillaExtract</p>
<p>Hmm I don’t care if it was atoms or molecules I just really hope my reading skills were ok yesterday :/</p>
<p>What was the NaOH question?</p>
<p>i think i got .1 g for a problem also.</p>
<p>i’m such an idiot, i’m a perfect scorer on math 2c and yet i can’t figure out that 18 x 334 J = 6000 J (I put 668 J, don’t even ask)</p>
<p>Ugh I could have SWORN it was ATOMS! But I<3Pi I agree :)…what IS this NaOH question? It sounds vaguely familiar</p>
<p>Yeah, I thought that people were saying that N2/H2 were atoms. I understand what they were saying, now.</p>
<p>I feel as if the NaOH question was something like: how many g of NaOH must be dissolved to make xmL of xM NaOH(aq)? Maybe?</p>
<p>So the consensus is molecules? THANK GOD</p>
<p>For the H202 question. It wasn’t 2. I think it was some high number. Maybe 8?</p>
<p>I wish I remembered the equation to that one!! Does anyone remember it?</p>
