Using the reaction equation CaCO3 = CaO + CO2 Calculate the mass of calcium oxide

Using the reaction equation CaCO3 = CaO + CO2 Calculate the mass of calcium oxide, which forms during decomposition of 50 g of calcium carbonate.

The decomposition reaction of calcium carbonate when heated is described by the following chemical equation:

CaCO3 = CaO + CO2 ↑;

Let’s calculate the chemical amount of calcium carbonate. To do this, we divide its weight by the mass of 1 mole of the substance.

M CaCO3 = 40 + 12 + 16 x 3 = 100 grams / mol;

N CaCO3 = 500/100 = 0.5 mol;

The same molar amounts of calcium oxide and carbon dioxide can theoretically be obtained.

Let’s calculate the weight of calcium oxide. To do this, we multiply the amount of the substance by the weight of 1 mole of the substance.

M CaO = 40 + 16 = 56 grams / mol;

m CaO = 0.5 x 56 = 28 grams;
