What is Calcium Carbonate Limestone?
An example is when slaked lime (calcium hydroxide) is mixed into a thick slurry with sand and water to form mortar for building purposes. When the masonry has been laid, the slaked lime in the mortar slowly begins to react with carbon dioxide to form calcium carbonate (limestone) according to the reaction: Ca(OH)2 + CO2 → CaCO3 + H2O.

Solved A sample of limestone (calcium carbonate, CaCO3 ) is
A sample of limestone (calcium carbonate, CaCO3 ) is heated at 960. K until it is completely converted to calcium oxide (CaO) and CO2. The CaO is then all converted to calcium hydroxide by addition of water, yielding 8.29 kg of solid Ca(OH)2. Calculate the volume of CO2 produced in the first step, assuming it to be an ideal gas at 960.
