Chemistry - August 2006

I want to remember the following reactions:
1)CH3-CH2-CH3------> CH4+CH2=CH2
2)CH3-CH2-CH2-CH3----->CH4+CH3-CH=CH2
3)2CH3-CH2-CH3----->CH2=CH2+CH4+CH3-CH=CH2+H2
Please give me any tricks or techniques.

If protons and electrons experience mass defect in atomic structures than the size and mass of the atomic elements in the peirodic table are not the same mass. Hence, Electron mass is not constant depending on which structures its trapped in?So how is mass structure calculated?

My boyfriend and I just moved from our old place to a new one in a different city. He says he can smell the chlorine in the water here and his skin has been breaking out. He's afraid that we'll have to move if it doesn't clear up. Could it be that or is it probably stress from the move or something like that?

Heres and experiment, you get 3 cans of beer, three containers, in the first container you put plain cold water, in the second container you put cold water and some ice, in the third container you will place water ice and some salt (as to make the solution salty). Now placing the cans of beer one in each container and leaving it for 15 minutes. Taking out the beer from each container and testing the temperature of each beer. Why is it that the can of beer in the salty water and ice was the coldest?
As in is there a reaction between the ice and salt water that cools the beer the most? or what?

I am a visual and analytical person and supposedly math isn't used that much like in General Chemistry nor Inorganic Chemistry. Some people tell me is the easiest class of all the Chemistry classes and other tells me is the worst.

I am not a numerical person and I have had trouble with the past classes Chem classes but I passed them.

Being a visual person do you think is going to be better for me?
