I am studying meteorology ( a required course ) and am having difficulty understanding the affect of pressure in the atmosphere on molecules. Any information or websites that help explain this would be much appreciated.

In a constant pressure calorimeter, 199 mL of a 1.00 M alkaline earth metal (Me) chloride solution were added to 199 mL of a 1.00 M potassium sulphate solution. The total heat capacity of the calorimeter including all the contents was 1.75 kJ oC-1. The temperature in the calorimeter rose from 24.50oC to 28.42 oC.
Paying particular attention to sign and significant figures,
calculate the enthalpy change, in kJ, for the reaction:
Me2+ (aq) + SO42- (aq) = MeSO4 (s).
Me is the alkaline earth metal in question.
If you wish to use scientific notation, use the "e" format - eg. 7.31e4 = 73100 & 1.90e-2 = 0.0190.

I know Newton's 2nd law Fnet=ma, and yet I have no idea how to prove this, I think the question is asking for some invented math problem, and this troubles me greatly.

In Geometry Postulates don't have to proven, but theorems do. Theorems can be proven by other theorems, defined terms, and undefined terms. This is exactly like evolutionism and Creationism, isn't it? Evolutionism is a postulate, there is no proof for it. Creationism has tons of proof backing it up, making it a theorem. Why do people agree with something that has no proof instead of something that has 6,000 years behind it to back it up.

permutation mapping problem:


Two permutations a and b are said to be disjoint, if a(i) not equal to i implies that b(i) = i, and, b(j) not equal to j implies that a(j) = j. prove that disjoint permutations commute with one another.

thank you.
