<p>the sig fig question was 1.00</p>
<p>11.001/11.0 = 1.00</p>
<p>VERY is very debatable...
so i answered TRUE</p>
<p>and do they take off points for getting T/F/CE problems wrong.. cause the chances of guessing of those are less than 1/9</p>
<p>copper's reactivity is lower than that of hydrogen. So there is no reaction.</p>
<p>werent the answers for that ranging from 0-4 atms? i think i put 2</p>
<p>it was only talking about reactivity...there was no mentioning of water...although u can use H2O to determine if it is highly reactive or not, but thass not the best way to do it
and i actually left it blank cause it was too confusing</p>
<p>like one of the answers was .033 and one was in the 4 range. what werre the exact numbers? wasnt one of them 23.2 degrees?</p>
<p>wat is the actual question, i dunt remember this one</p>
<p>its defintely not CE</p>
<p>do u guys remeber any other mc questions from 24-70?</p>
<p>the one about atms was 3.00 atm</p>
<p>okay??</p>
<p>watu guys think about the test over all</p>
<p>copper aint gonna react when you put that shiz in water! copper is not very reactive!</p>
<p>Think about it this way. If you dropped a copper penny into hot water, does it explode (or fizz, or do anything special)? And isn't our Statue of Liberty made of copper originally? It has since then changed color, indicating that it has reacted to copper oxide.</p>
<p>i guess i agree, but i left it blank so w/e</p>
<p>any other questions u remeber</p>
<p>How did you do the problem calculating the partial pressures of O2 and N2 in the cannister. It was 1.5atm in there, i forgot the rest of the problem.</p>
<p>0.5 atm for O2</p>
<p>first three cause and effect were F-F right</p>
<p>it was O2 is .5 atms. dont remember the numbers, but all u do is multiply each elements mole fraction by the total pressure</p>
<p>I put keq= H times I/ HIsquared for one of them, but i think its wrong, cuz i think now it asked about what is not true. do u al remember?</p>
<p>yeah 0.5 for O2</p>
<p>I think I got like a 700-730</p>
<p>Anyone know what the curve should be like or what last years was like?</p>
