Elementary analysis showed that an organic compound contained C,H,N and O as its elementary constituents. A 1.279g sample was burned completely as a result of which 1.60g of carbon dioxide and .77g of water were obtained. A separately weighed 1.625g sample contained .216g nitrogen. What is the empirical formula of the compound?

When solid ammonium dichromate is heated, it decomposes to Cr2O3(s) and N2 (g) and H2O (g). In a given experiment, the following data were obtained.
Crucible + ammonium dichromate. 33.622g
crucible + Cr2O3(s). 29.608g
What is the weight of the crucible?

Water is added to 4.267 g of UF6. The only products are 3.730 g of a solid containing only uranium, oxygen and fluorine and .970 g of a gas. The gas is 95% fluorine, and remainder is hydrogen.

A) from this data, determine empirical formula of the gas.
B) what fraction of fluorine of the original comp is in solid and what fraction in the gas after the reaction?
C) what is the formula of the solid product
D) write a balanced equation for the reaction between UF6 and H2O. Assume that the empirical formula of the gas is the true formula.
