What is the empirical formula of the product produced when 15.9kg of copper oxide reacts with 8.8kg of carbon dioxide?
- Reacting masses of CuO is 15.9 and CO2 is 8.8 kg
- Mr of CuO is 63.5+16=79.5
- Mr of CO2 is 12+ (16*2) = 44
- So if you divide the reacting masses by the Mr you get for CuO- (15.9/79.5)=0.2, and for the CO2 is (8.8/44)=0.2
- So they are both in the ratio of 1:1
- 1CuO+1CO2 -> CuCO3
