| The decomposition reaction of calcium carbonate occurs in accordance with the following chemical reaction equation:
CaCO3 = CaO + CO2;
From 1 mole of calcium carbonate, 1 mole of calcium oxide and 1 mole of carbon dioxide are formed.
Let’s determine the chemical amount of a substance in 10.6 grams of calcium carbonate.
M CaCO3 = 40 + 12 + 16 x 3 = 100 grams / mol;
N CaCO3 = 10.6 / 100 = 0.106 mol;
Let’s calculate the volume of 0.106 mol of carbon dioxide.
One mole of gas under normal conditions fills a volume of 22.4 liters.
The volume of carbon dioxide will be equal to:
V CO2 = 0.106 x 22.4 = 2.374 liters;
