What amount of carbon dioxide is produced by the decomposition of 200 g of calcium carbonate?
| May 20, 2021 | education
Reaction equation: CaCO3 = CaO + CO2
Find the amount of calcium carbonate substance n = m / M = 200 g / 100 g / mol = 2 mol. (M-molar mass, determined by the periodic table). According to the reaction from 1 mol of calcium carbonate, 1 mol of carbon dioxide is formed, which means the amount of CO2 is equal to the amount of CaCO3: n (CO2) = 2 mol.
Answer: the amount of carbon dioxide substance is 2 mol.
