<p>yes that's what i meant, only by chance did i even remember the specific elements, just an example :)</p>
<p>whoa thanks alot everybody for the answers and explanations</p>
<p>hey what do you guys think my score will be with 14 wrong and 4 omitted??? any feedback plz thansk</p>
<p>NH3 was the correct answer because it was a weak base. Weak acid was wrong.</p>
<ol>
<li><p>Mass of water would not be needed in figuring out the molar mass of the gas in that diagram...both pressures were necessary. E was like atmospheric pressure, which matters because it is like a barometer, except using water instead of mercury.</p></li>
<li><p>Catalysts lower activation energy, but do not affect enthalpy (heat gained or released in the reaction)</p></li>
</ol>
<p>Worth2try, increasing the pressure would not affect the gases' concentration. Only increasing the volume would affect their concentrations. However, the rest is right.</p>
<p>guys guys guys what u think 14 wrong and 4 ommiteed is?</p>
<p>increasing the pressure would decrease the volume..</p>
<p>In terms of ideal gas law, it has the same effect; but not in terms of thermodynamics.</p>
<p>cmon some one answer my question, what do u think 14 wrong and 4 ommited is?</p>
<p>eh, maybe maybe</p>
<p>bonder, multiply your number wrong by 1.25 add the number you omitted, then subtract the number you get from 85.</p>
<p>so you'd get a raw score of 63.5</p>
<p>ok lets continue back to readding and answering questions?
any1 remember any others?</p>
<p>bonder, my estimation would be in the lower 700's range
730 max I think</p>
<p>Worth2try, you are right. The equation is about equilibrium, and a change in pressure will shift equilibrium in gases towards the side with the lower moles of gas.</p>
<p>I think the question said "compressing the gases", which meaned both increasing the pressure and reducing the volume. So equilibrium concentrations are affected</p>
<p>What was the answer to the question where it asked about which assumption one would have to make in order to find the molar mass of the gas?</p>
<p>Mass of water.</p>
<p>What has chloride in in around question #5? Choices were nitrate, halide, hydrate, hydrocarbon?</p>
<p>Halide (halogen + ide = halide)</p>
