Can someone tell me why mummies' skin are that dark color?

I don't think it's true.

But if it is, I want to do some things before the civil war.

Thanks for opinions.

Does anyone believe this story?

2) Solving for T, you actually get 353 K. Then, 353 - 273 = 80 C.

Does that make the air over the top lighter than the air below the lifter?

4) Elements as molecules : Noble gases and H2

Covalent lattices :

I think this is what you mean.

Okay, well if someone can explain this then.

I don't think the video is movie magic though.

Can someone explain this to me?

25 mL of 1.6 M acetic acid :

0.025 L * 1.6 mol acetic acid / L = 0.04 mol acetic acid; for the molarity you have to b given volume of solvent the acetic acid will be dissolved in

10 mL of 0.160 M sodium acetate :

0.01 L * 0.16 mol sodium acetate / L = 0.0016 mol sodium acetate

delta Hideal- delta Hreal = ?

< 0, > 0, = 0 ?

and,

delta Sideal- delta Sreal = ?

< 0, > 0, = 0 ?

Also, if someone could PM about how to get math symbols in revised forum, it would help. Thanks.

um, i had some errors in there.

man, i have crazy night terrors.

(150e-3 L) * (0.1235 M) = 0.018525 mol FeSO4

0.01825 mol FeSO4 * 135.9082 g / 1 mol FeSO4 = 0.0001342818166968586148591475716697 g FeSO4

kenel,

check this out.

dS = C ln (T2 / T1)

C = heat capacity.

then,

dG = dH - T dS

so i got it wrong on the test.

thanks.

hope dS wasn't given to me on the exam then.

Can I calculate dG with dH and without dS?

too many carbs

I read in Sci Am or Discover that the 3D galaxy could be imagined being located on a very bumpy piece of paper, with its length and width being one flat plane and the dips and crests of the paper visualized in the third dimension. With galaxies on this piece of paper, you have the universe. The fourth dimension would be stacks of these bumpy pieces of paper.

pH = 13 for a weak base?

ln a * e^-(a^(a+1)) = x + ln x

How did you make that first one?

By the way, does anyone know good math forum?

What do you think of the possibility of being silicon based instead of carbon based? Both can form four bonds.

Where are the Martians anyways? I heard they're underground.

What kind of advanced maths would I need to understand some advanced physics?

I know calculus inlcuding triple integral calc, differential equations, and statistics.
