A 1.397 L container of O2 at 773.6 mm Hg was connected to another evacuated container which had a volume of 1.030 L and separated by a valve. What was the final pressure in atmospheres if the valve was opened and the gas allowed to expand into the other container?

can sodium hydroxide and sodium polyacrylate be absorbed into the body through skin contact. If so would they stay in the body and what kind of damage would they do: eg. would the sodium hydroxide damga fatty tissue and sodium polyacrylate remove fluid from body tissue? What kind of medical treatment could be made?

1. You have in your possession an acid made up of 68.1% oxygen, 29.8% nitrogen, and the rest hydrogen. Assuming that the molecular formula is the same as the empirical formula, determine the formula of your acid.

2. Name the acid
3. Draw the lewis structure
4. Give the oxidation numbers of each element in acid.
5. Does your acid contribute to acid rain? If so explain how, using balanced chemical reactions and listening sources of your pollutant.
