<p>What do you get by passing oxygen gas (O2) through a solution of permanganate (MnO4-)?</p>
<p>Do you get a precipitate? Is it a redox reaction?</p>
<p>I would like to say that you will get Mn2+ and something else. Redox reactions are not my strong point.</p>
<p>Yeah, it is not my strong point either. I just have this question from one of the practice tests, but I don't have the answer or any reasonable idea of what the answer is?
Anyone else?</p>
<p>Also: is Ag+ + HCl → AgCl(s) + H+ spontaneous? My book says it is, but isn't this reaction going against entropy? It is getting more orderly, since Ag+ and HCl, which are ions in the solution, are more disordered than the solid AgCl and H+ ion. So wouldn't this reaction have a negative entropy and be nonspontaneous?</p>
<p>Someone really good in Chemistry please help?</p>
<p>Can anyone please tell me the difference between the lewis structures of sulfur trioxide, sulfate, and sulfite?</p>
<p>sulfur trioxide is SO3
sulfate is SO4 2-
sulfite is SO3 2-</p>
<p>Basically the Lewis diagrams for sulfur trioxide and sulfite look the same, although the sulfite ion will have two more electrons in it. Sulfate looks a bit more different from the other two though because it has an extra oxygen attached. Sorry I can't draw it out for you, but I hope you get the gist of it.</p>
