<p>For the question about which was under greater pressure</p>
<p>Did u guys put </p>
<p>Scientist 2 because it was 100 km below?</p>
<p>Also, for the “Student W” question</p>
<p>Was the last question or the second to last question?</p>
<p>I thought for the second to last question it asked for the longest period which was clearly the 3rd option, no?</p>
<p>It wasn’t CH4 because it asked for what forms petroleum and scientist 2 set inorganic compounds formed a hydrocarbon. The other 2 were involved in the formation while the organic CH4 couldn’t. Please tell me if I’m wrong</p>
<p>sorry ur wrong, i specifically remember reading something about it had to have a carbon molecule in it</p>
<p>Adude I was thinking what ur thinking but #2 mentions methane specifically is a bridge to petroleum.</p>
<p>for the question asking about the distance for the syringe thing</p>
<p>was it increasing, decreasing?</p>
<p>and what was the formula for the NO and O2 thing?</p>
<p>Uh, well… C = Carbon, H = Hydrogen, and that choice was the only option with the two together, so I picked that one.</p>
<p>Did u guys get 0% for the last genotype question?</p>
<p>Adude, I agree with your argument… that confused me a little. It could be all 3, I II and III wasn’t a choice.</p>
<p>master - yeah</p>
<p>Was the one that had the list NO or soemthign remained like trial 4? Or whatever trial had another 10 of something left other then the 20 for NO?</p>
<p>2no + o2 = 2no2</p>
<p>I’m pretty sure the formula was NO + 2O > NO2 or something like that.</p>
<p>master, 50% green</p>
<p>O is only ever O2…right?</p>
<p>2NO + 2O–> 2NO2; i just used basic stoichiometry lol</p>
<p>College Addict…Same here lol</p>
<p>@college</p>
<p>r u sure of the 2 coefficient in front of both?</p>
<p>I thought it asked to refer to trial 2 where there were different amounts of NO and O</p>
<p>it wouldn’t make sense…its really a law of chemistry. Unless they did the experiment in some other dimension, sorry no it has to be balanced</p>
<p>yeah theres no 2 in front of the oxygen</p>
<p>? O cannot exist like that. O is always O2</p>
<p>the answer was 2NO + O2 = 2NO2</p>
