<p>wht about the question about equilibrium. was the answer I,II,III?</p>
<p>Oh in the second part of the early questions, there was no reduction reaction right?</p>
<p>how about the question on global warming or something?
was the answer something about chlorofluorocarbon in the ozone layer or greenhouse effect gases in the atmosphere??</p>
<p>what about that question that gave heat as a reactant and you want to create more C. do you increase temperature?</p>
<p>Equilibrium I remember as I,II. They don’t have to be in equal concentrations.</p>
<p>i put greenhouse</p>
<p>answer for equi was I and II, III is definitely w/o a doubt not true</p>
<p>what was the equilibrium question??</p>
<p>temperature yes.
I remember Chromium IV being reduced to Chromium metal.
What was the global warming question?</p>
<p>yes you add heat to increase product yield and the greenhouse q was yes CO2 contributes to greenhouse, yes it forms an acid with water, but no that does not explain why CO2 contributes to the greenhouse effect</p>
<p>lol stop bringing in questions that weren’t on the test
There was nothing on CFCs.</p>
<p>Yes, equilibrium was I (observable properties constant) and II (rates equal)
Yes, increase temperature to give more C</p>
<p>@ princeton, I believe there was (chromium ion to chromium metal)</p>
<p>oh shoot. i read the answer choice wrong. and wasnt the Cr4+ to Cr reduction?</p>
<p>yes, reduction</p>
<p>increase in temp, catalyst speeds it up.
and pk0123, leo says ger.</p>
<p>yes that’s right about chromium; I remember an oxidation state question that was 5 to -3 for the answer</p>
<p>Yup Princeton, it involved 4 zincs being oxidized to +2, so all 8 electrons went to nitrogen.</p>
<p>i don’t remember a question with catalyst as an answer…I do remember a place where it said catalysts lower act energy</p>
<p>yup, i got +5 to -3</p>
<p>anything else?</p>
<p>dunno…guess we just wait now…</p>
