PLEASE HELP WITH MY CHEM PACKET PLZ
1. Sulfur and oxygen can react to form both sulfur dioxide and sulfur trioxide. In sulfur dioxide, there are 32.06 g of sulfur and 32.00 g of oxygen. In sulfur trioxide, 32.06 g of sulfur are combined with 48.00 g of oxygen
a. what is the ratio of the weights of oxygen that combine with 32.06 g of sulfur?
b. how do these data illustrate the law of multiple proportions?

2. Describe what part of dalton's atomic theory each chemical statement relates to.
a. H2 + Cl2 -> 2HCl
b. There are 3.01 x 10^23 atoms in 20.04 g of calcium
c. Lead does not change to chromium when it forms lead hydroxide

3. Noble gas consists of three isotopes of masses 19.99 amu, 20.99 amu, and 21.99 amu. The relative abundance of these isotopes is 90.92%, 0.257% and 8.82% respectively. what is the average atomic mass of this noble gas? what noble gas is this?

Did humans develop the 5 senses because of what was around us? Did we develop a nose because of the presence of smell, did we develop ears because of the presence of sound, did we develop eyes because of the presence of light??? If we could grow some sort of other organ on our face or body, what would it do? Is it even possible to grasp that concept? I sure can't think of anything else we could do.

How is it that when you shave hair on your body, it grows only to a certain length, how does your body know when to make it stop growing and how does it know you cut it? Also they say the hair on our head usually only grows a certain length, why does it stop growing?

I know that to find the vertical asymptotes, you set the denominator equal to zero, but how do you find the horizontal or slant asymptotes?

For example: (2x-4)/(x^2-4)
The denominator is x^2-4, so that's (x+2)(x-2).
So the vert. asymptotes are x=2 and x=-2.
What about the horiz./slant asymptotes?

The promise of nano-molecular robots being able to repair cellular damage, coupled with this having been declared the era of brain science, the ability to regenerate spinal tissues in other mammals, and the successful complete sequencing of the human genome are all encouraging examples of technologies rapidly approaching practical applications for the common man, and much more to the point, the applicability to treat severe trauma in medical situations. Cryonics relies upon the rational extrapolation of the power of such things to provide for the hope of revival of damaged patients in the future. So when will we be seeing such "time capsules" walking again in our midst?

Hi, I have a question about buoyancy and water displacement. I have tried to figure this out for over an hour, but I have figured out nothing yet.

The density of water is 1.0 g/cm3. How many kilograms of water does a submerged 120-cm3 block displace? One kilgram weighs 9.0N. What is the buyant force on the block?

* The 3 next to cm is to the power of 3.
