<p>@ bananas
I got about 4 CEs</p>
<p>can you specify the questions for the I II and III</p>
<p>I got three total T T CE, and for the inverted tube and atmosphere… I think I put T T CE for that one because the second part said total pressure inside is the vapor pressure + pressure of gas.</p>
<p>I didn’t get T T CE for the rxn diagram, and based off that link earlier I think its probably 4 then.</p>
<p>@abcgummy</p>
<p>one was like in oxidation reduction reaction,
I.dont remember
II.atomic number can change
III.oxidation number can change</p>
<p>i put I and III</p>
<p>Do you remember the questions…</p>
<p>i put I and III too for that question.</p>
<p>I agree there was a I,II and III for the question about acid being proton donor, h plus maker etc.</p>
<p>@ abcgummy101 Acid donates protons and hydrogens (arrhenius and bronsted/lowry, but accepts electron pairs (lewis). The answer was not the electron donor one, but the other two.</p>
<p>I think I got 5 TT CEs. Uh oh.
Does anyone remember the answers to the series of questions like
What happens if you add 0.001 M of HCl to this and so on…</p>
<p>abc was there something about it being an electron something?</p>
<p>bananas
I put 10ml of .01 M of H2SO4</p>
<p>I put the H2SO4 one as well.</p>
<p>For the question that said how much .0200 M KOH would you need to neutralize .100 L .0200 M HC2H3O2, what was the answer?</p>
<p>I put .100 L, but that couldn’t have been it because HC2H3O2 is a weak acid and does not completely ionize. But how could you choose between 20 mL and 40 mL without knowing the Ka or something like that?</p>
<p>what about the question with the ph < 7
that was h2s04 right?</p>
<p>It was 0.100 L. It doesn’t matter if it’s weak, the hydroxide will suck the proton out of the acetic acid whether or not it wants to give it up.</p>
<p>@xks i put .1 L / 100 ml too.</p>
<p>the .001m/.01m questions were asking about adding strong bases to acids (i think?). So the pH<7 would be adding the base to H2so4 since it has 2 hydrogens, instead of one, making it more acidic than 7. strongacid/base makes ph7.</p>
<p>@ user YES I HOPE SO</p>
<p>@xks I put 100mL
yea I was kinda eh about that too</p>
<p>@xks4892</p>
<p>I believe I used M1V1 = M2V2. I got .100 L as well.</p>
<p>For the question that said how much .0200 M KOH would you need to neutralize .100 L .0200 M HC2H3O2, what was the answer?</p>

<p>OMG…this was the last question i did. I wanted to be .1L but i new it couldnt possible be correct. i couldnt choose between A and B, so I put B cause that is the answer I put when i guess.</p>
