<p>“for 9 grams of H20 … was one of the answers III. 11.2L of water… ? something like that”</p>
<p>i said I and III for that. i think I was how many moles of Hydrogen are produced, which was 9 times 2 /18 so 1 was correct.</p>
<p>also, what were the products were H+ Na+ and OH- or something like that…? or was it H2</p>
<p>but it said electrons
i remembered there was no word “valence”…</p>
<p>Tin(sn) wasnt an answer choice, but it actually has 2, its actually pretty interesting, tin(II)chloride is ionic while tin(IV)chloride is covalent</p>
<p>pie231 is right. they didn’t specify valence electrons or not</p>
<p>sunny i put just fe too, but google says b2o3 exists…</p>
<p>and why did i put chromium for that one? im guessin i read the electron configurations wrong or something… no clue</p>
<p>@tvremote and sunny
the x2O3 i initially thought it was fe only (and fe works because Ferric has a 3+ oxidation state) but i just checked and B2O3 does exist too so it’d be Fe and B</p>
<p>It was false because it didn’t specifically state valence. electrons just meant overall number.</p>
<p>x2o3 -> wasnt it B?
Fe can be many different ions
it didn’t specify if it was Fe III or not so i just but
element B only.</p>
<p>it’s both fe and b. because both have charges of plus three</p>
<p>yea i agree with the above poster. i checked that as well. unfortuntaly i put FF for some lame reason so i got it wrong.</p>
<p>also pretty sure the water/salt thing was evaporation</p>
<p>Adding on to </p>
<p>ink by distill (wrong)
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</p>
<p>I REMEMBER( took it an hour ago!)</p>
<p>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</p>
<p>@soccerrocket93 - I thought that was the answer too, but it said that it produced liquid water, and the 11.2 L only applies to gasses. In this case, you would get 9 grams of H2O liquid, which would take up about 9 mL.</p>
<p>Yea, i didn’t know that it meant one type of fe because there’s a lot of charges for Fe.</p>
<p>NO2 because N has 5 valence electrons, and O2 will have 16. So an odd number of Valence Electrons</p>
<p>yeolgong: NO2 is a free radical. it has one unpaired electron because the total number of valence electrons is 17</p>
<p>@yeolgong: I think the highest pH was H2PO4?</p>
<p>And can someone explain the NO2 or N2O question? I don’t remember it at all…</p>
<p>when water evaporates does the rest of it become cooler?</p>
<p>density of methanol or whatever the substance was? i put 0.7</p>
<p>i think it was NO2 for the unpaired electron</p>
<p>reply
evaporation means liquid take energy and become gas. so surrounding loose energy, so cooler.</p>
<p>NO2 (N;5, O;6 valence electrons)–>this is a radical molecule. odd electrons. unpaired electrons. (same 3 expressions.)</p>
<p>@EducationOD… you might be right.</p>
<p>I think it was just I, not I and III. It wasn’t 11.2L because I think it was a liquid reaction, not gas.</p>
<p>Question about burning H2 and O2, left 1.0 mol O2?</p>
<p>I think the highest pH was HCl… it dissociates completely and I think they all had the same concentration.</p>
<p>There was a gas laws question about changing the temperature and pressure, if you plugged it into the ideal gas equation I think it was 400k and 1.0 atm.</p>
<p>i don’t think it’s self-reliance, i thought it was industrialization:::</p>
<p>wiki:
The New South campaign was championed by Southern elites often outside of the old planter class, in hopes of forming partnerships with Northern capitalists in order to strengthen the social, political and economic status quo of the South</p>
<p>The antebellum South was largely agrarian and sought to preserve its cultural identity in departing from the Union, which led to the irrepressible conflict. After the war, the South was impoverished and seemed to be in great need of an alternative economy. The New South was no longer to be dependent on banned slave labor or predominantly upon the raising of cotton, but rather industrialized and part of a modern national economy. Henry W. Grady made this term popular in his articles and speeches as editor of the Atlanta Constitution. Richard H. Edmonds of the Baltimore Manufacturers Record was another staunch advocate of New South industrialization.</p>
