Question

When quicklime slakes in the atmosphere, a mixture of calcium carbonate, CaCO3 and calcium hydroxide Ca(OH)2,
forms because of the reaction of quicklime with carbon dioxide and water in the atmosphere. This is the time consuming reaction that occurs when mortar sets. Write balanced equations that represent the setting of mortar

Answer 1

1) CaO + H2O --------> Ca(OH)2
quicklime + water vapor--------->slaked lime


2) CaO + CO2 --------> CaCO3
quicklime +carbon dioxide--------> marble chips

Answer 2

CaO + H2O ===> Ca(OH)2

CaO + CO2 ===> CaCO3
