When limestone (solid CaCO3) is heated, it decomposes into lime (solid CaO) and carbon dioxide gas....
When limestone (solid CaCO3) is heated, it decomposes into lime (solid CaO) and carbon dioxide gas. This is an extremely useful industrial process of great antiquity, because powdered lime mixed with water is the basis for mortar and concrete - the lime absorbs CO2 from the air and turns back into hard, durable limestone. Suppose some calcium carbonate is sealed into a limekiln of volume 250. L and heated to 870.0 °C. When the amount of CaCO3 has stopped changing,...
