<p>I put Na2SO4 (or something similar) because Na replaces the H in HCL I think</p>
<p>NaCl is not a gas and H2SO4 is not a gas either</p>
<p>So I don’t remember a lot of the quesiton, but it was one of those like “this reaction occurs, what are the products?” and they give you the two reactants with 3 roman numerals and you choose
If i remember correctly, the roman numerals were
I. Ca(s)
II. NH3 (or NH4, don’t remember)
III. H2O</p>
<p>So I’m not even sure if those were the romans, but it was a question like this. Anyone remember more of the question or know the answeR?</p>
<p>I put Na2SO4 as well because sulfates react with acids to produce so2</p>
<p>@ nd3 II and III is the answer</p>
<p>i took bio and chem today. i don’t remember if the biomolecule question was on chem or bio. anyone remember it from chem?</p>
<p>what’s the ratio of hydrogen gas to oxygen gas formation in the electrolysis of H2O?</p>
<p>I said</p>
<p>2H2O –> 2H2 + O2</p>
<p>so I said 2:1</p>
<p>Agree?</p>
<p>was one of the choices for that 0.5:1 or was that a different question?</p>
<p>@nde: I read that question too quickly. Was it by mass or not? (Cause I said 8:1… uh oh)</p>
<p>lol who wants to estimate a curve for 700-800?</p>
<p>id say -4 to -5 is 800 and -15 would be around 700?</p>
<p>@timmy thanks</p>
<p>how many T T CE did you guys get? was the vapor pressure one T F?</p>
<p>was one of the choices for that 0.5:1 or was that a different question?</p>
<p>Different question</p>
<p>oh was that the right answer for that “different question”? lol</p>
<p>Does anyone remember the T/F question about the diffusion of NH3 and CO2 ( I don’t remember the question exactly. ) I knew a little about diffusion but I did not know how to determine which gas would diffuse more quickly. Anyone know what the answer was?</p>
<p>CO2 diffuses more slowly because it has a larger mass (Graham’s Law).</p>
<p>that one was F and F</p>
<p>anyone remember how many TT CE there were?</p>

<p>If that was the Ba into the like Basomethingsomething solution, then I put .1 to .1 and someone who i talked to after the test agreed (it was a limiting reactant problem)</p>
<p>I had either 3 or 4 TT CE’s I think.
It seemed like a lot. D:</p>

<p>What was the 2nd part of this question? The first part was definitely false, but what does the 2nd F correspond to?</p>
