A) One compound is isolated which contains only nitrogen, hydrogen, and chlorine. When a 1.376-gram sample of this compound is completely combusted, 0.478 g
of H20 and 0.372 g of N2 are recovered. Determine the empirical formula of this
compound

Look at the reaction below: ca(hco3)2 --> caco3 + co2 + h2o first, balance the reaction. once balanced, use dimensional analysis or another method to find out how many moles of carbon dioxide will be produced if we start with 16.5 moles of calcium bicarbonate (calcium hydrogen carbonate). = mol of co2 number needs to be reported to three significant figures.
