Another stupid question...but does it mean like multiply?
For example: 3^2
so would that mean 3 multiplied by 2?
or would it mean 3 to the 2nd power? (3 times 3)?

Okay, this is strictly hypothetical. Just for fun, that is. The only criterion for getting Best Answer is to make me say "Hmmm...Interesting." Got it?

It's the distant future, and scientists have just perfected a matter transporter that allows humans to travel great distances at essentially the speed of light. It works by rapidly encoding every bit of information about the atoms that make up your body (down to the tiniest quantum detail), then disintegrating you, beaming the information to your destination, and reassembling you atom-for-atom. I know, I know...it's pure fantasy. But here's the question: Is it still YOU? Does it have your memories, your hopes, your dreams? Or is it just a copy of you, albeit a remarkably precise one? What do you think, folks?

If it's NOT you, is that person still accountable for your debts? If a murderer travels through the matter transporter, can he or she still be tried for murder, even though it's not the "same person"?

in the figure above l is parallel to m and each circle is tangent to the other two circles at the labeled points. if each circle has diameter 8 and is tangent to one of the two lines, what is the distance, h between l and m?

http://local.wasp.uwa.edu.au/~pbourke/fractals/apollony/1.gif
yu have to add line L to the bottom circle as a tangent to the circle and M to the top two circles as tangent to both, with line h just on the side to show height but not a tangent (the picture just needs to have these three lines and it looks like the problem in my book)

1.calculate the work change in H at 298K and change in E for the combusition of one mole of sucrose at 25 degree C and 1atm pressure (use change in H sucrose = -2218kJ/mol)
C12H22O11(s) + 12O2(g) --> 11H2O(l) + 12CO2(g)
a. w= 0kj H=-5648kJ, and E=-5648kJ
b. w=0kj, H=5648kj and E=5648kj
c. w= 5648kj, H= 0kj and E= -5648kj
d.w=0kj , H= 0kj, and E= 0kj
e. none of the above.

A particular coal contains 4.3% sulfer by mass as an impurity. When the coal is burned, the S is converted to gaseous SO2. The SO2 enters the exhaust gases, where it is removed by reaction with powered CaO to produce solid CaSO3. How much by-product CaSO3, in tons, is produced by the burning of 1 ton of coal?
