A 2.00g sample of an oxide of bromine is converted to 2.936g of AgBr. Calculate the empirical formula of the oxide. (molar mass for AgBr = 187.78)
A. BrO
B. BrO3
C. BrO2
D. Br2O
E. None of these.

Which is mostly likely why many scientists reject the cold fusion theory

200. ml of 3.00 m nacl solution is diluted to a final volume of 500. ml. what is the molarity of the final solution?

A100 kmol/h stream that is 97 mole% carbon tetrachloride (ccl4) and 3% carbon disulfide (cs2) is to be recovered from the bottom of a distillation column. the feed to the column is 16 mole% cs2 and 84% ccl4, and 2% of the ccl4 entering the column is contained in the overhead stream leaving the top of the column. calculate the mass and mole fractions of ccl4 in the overhead stream, and determine the molar flow rates of ccl4 and cs2 in the overhead and feed streams. 12. mw_ccla- 153.82; mw_cs2-76.14.
