<p>H+ + CaCO3 produces:</p>
<p>1 mol Ca2+
2 mol CO2
1 mol H2O</p>
<p>??</p>
<p>No for the water thing, its def 11.2 b/c you convert to moles or something. doesn’t matter that its a liquid.</p>
<p>i think d was the boiling point
it was naoh</p>
<p>for the density of methanol… what did you guys do? i just took the mas and divided it by the volume given… so i remember getting 3.3 or something like that…</p>
<p>actually, the 22.4 L rule at STP only applies to gas so I’m pretty sure that the fact that it is a liquid does matter, liquids have a constant volume</p>
<p>H+ + CaCO3 produces:</p>
<p>1 mol Ca2+
2 mol CO2
1 mol H2O</p>
<p>i said 1 and 3
because you didn’t have to balance, so didn’t need 2 moles of C02</p>
<p>tvremote, how can you find the volume from the number of moles?</p>
<p>Edit – yeah education it was NaOH, I didn’t remember correctly</p>
<p>@soccerrocket93 - I sure hope so.
Also, wasn’t the substance with the highest pH NaOH, because it’s a strong base?</p>
<p>ink by distill (paper chrom)
water and ethifej (Distill)
sand and salt (filter)
h20 cryatal (hydrate)
H and metal (hydride)
Tin for more ox states
h20 add salt … you get lower freeze pt (right), higher density (i put false) so just III but i think it might be II and III
CO2 not harmful
7 carbon atoms (last question)
separate by evaporation (salt)
mendelev … T F
3 TT CE’s in a row in second column
only one TT CE in the first column
one TT CE was it was about evaporation and not having enough energy and they have less temp (ACTUALLY MIGHT BE FALSE
NO2 everything has an unpaired
hydrocarbon- organic
there were a lot of As in a row on the bottom of first column.
1.triple bond: N2
2.polar: NH3
3.180degrees: CO2
organic compound: hydrocarbon
phase diagram: C was triple point
phase diagram:E was critical pt
phase diagram:B was (one the line) boiling pt
reaction Fe2+ -> Fe3+ + e- was oxidation
other one was precipitation
other one was …?
3TTCE in a row on second column (one was catalyst)
balance for (NH4)2 thingie: 4H2O
i put n2o… but i guess it is n02. can anyone explain?
highest pH: HOCL or H2PO4 or HC2H3O2 or NAOH or something separating water and
for 9 grams of H20 … NOT 11.2L thats only for gases. answer:I. 1mol H
x203 –> Fe and B</p>
<p>damn i got that one wrong. </p>
<p>i did: H+ + CaCO3 -> HCO3 + CaCl :(</p>
<p>i actually had CO2 and H2O as products but changed it</p>
<p>Oh shiet… did it ask for highest pH or lowest pH? CRAP!!!</p>
<p>yeh i put evaporation too</p>
<p>guess I got that wrong, but I though the choice was like 8.5 g of water or something. I don’t remember a 9 g choice</p>
<p>EducationOD, yea NaOH. That was the first thing i crossed out, then realized it was highest ph, not lowest</p>
<p>md5hash wat was it asking?</p>
<p>NOOOOO!</p>
<p>i should have read more carefully. score is steadily dropping.</p>
<p>for that one with the organic compound, was it CH3 or C2H3</p>
<p>For one of the T/F questions</p>
<p>Mendeelv predicted gallium bf it was discovered (T)</p>
<p>Because gallium has the same totally # electrons as aluminum -> Was the true or false? Because it has the same valence electrons, but not same total electrons… so I put false. 
But it seeeems like it would be T,CE</p>
