1. The chemical reaction is given CaCN2 + 3 H2O → CaCO3 + 2 NH3 follow this equation and calculate how much CaCN2 is required to form 12.6 moles of ammonia? Given that the percent yield is 65.8%?
2. When 42.52 g of CH3CH2OH (ethanol) is combined to 125g of H2O (water) then find out what will be the mole fraction of ethanol?
