I need some ideas on what to write my paper on. It's an analysis paper where I can analyze one of the following

-paintings/visual arts

-movies

-poems

-music

and I have to focus on one of these topics

-gender issues or sexual identity

-economic class

-generational issues

I would appreciate any ideas, because I'm stuck and can't really thing of anything

thnk you in advance :]

The rate of a particular reaction quadruples when the temperature is increased from 15°C to 60.°C. Calculate the activation energy for this reaction.

Cyclobutane, C4H8, consisting of molecules in which four carbon atoms form a ring, decomposes, when heated, to give ethylene.

C4H8(g) → 2 C2H4(g)

The reaction is first order. In an experiment, the initial concentration of cyclobutane was 0.00165 M. After heating at 450°C for 455 s, this was reduced to 0.00131 M. What was the concentration of cyclobutane after a total of 847 s?

Bone was dissolved in hydrochloric acid, giving 46.0 mL of solution containing calcium chloride, CaCl2. To precipitate the calcium ion from the resulting solution, an excess of potassium oxalate was added. The precipitate of calcium oxalate, CaC2O4, weighed 1.437 g. What was the molarity of CaCl2 in the solution?

how would I calculate the molar mass of Na2CO3 x 10 H2O?

Can anyone tell me how to solve this? I've been trying but nothing seems to be correct, i thought i was suppose to use the equations q=mcdeltaT but i keep getting the wrong answer...help plzzz

How much heat must be added to 22.3 g of solid sodium, Na, at 25.0°C to give the liquid at its melting point, 97.8°C? The heat capacity of solid sodium is 28.2 J/(K·mol), and its heat of fusion is 2.60 kJ/mol.

Yea, so i checked to see that my sound cards are installed and they are, but my speakers still don't work, also i opened my speakers and plugged them back in and made sure everything was connected.....still dsnt work!!! neone help me plzz...its getting real frustrating =/
