A 18.7 sample of CaCO3 was treated with aqueous H2SO4, producing calcium sulfate, water and 3.65 g of CO2(g). What was the % yield of CO2?

Tetraphosphorous hexaoxide is formed by the reaction of phosphorous (P4) with oxygen gas. If the reaction of 26.2 g of phosphorus (P4) with 67.3 g of oxygen produces 21.0 g of Tetraphosphorous hexaoxide, calculate the percent yield for the reaction.​

When 33.9 g of CH4 reacts completely with excess chlorine yielding 52.0 g of HCl, what is the percentage yield, according to CH4(g) + Cl2(g) → CH3Cl(g) + HCl(g)
