Carbon dioxide is produced by the decomposition of calcium carbonate. The reaction product yield is 80%.

Carbon dioxide is produced by the decomposition of calcium carbonate. The reaction product yield is 80%. Calculate how much carbon dioxide will be obtained from calcium carbonate weighing 100 kg.?

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

CaCO3 = CaO + CO2 ↑;

Determine 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 = 100,000 / 100 = 1,000 mol;

Taking into account the reaction yield of 80%, 800 mol of calcium oxide and carbon dioxide will be synthesized.

To calculate its volume, you need to multiply the amount of substance by the volume of 1 mole of gas (filling volume 22.4 liters).

V CO2 = 800 x 22.4 = 17,920 liters = 17.92 m3;
