Limestone is quarried and is used for building, making concrete, making cement and making mortar and glass.
Carbonates react with acids to produce carbon dioxide, a salt and water.
calcium carbonate + hydrochloric acid → carbon dioxide + calcium chloride + water
CaCO3 + 2HCl → CO2 + CaCl2 + H2O
Calcium carbonate (Limestone) is damaged by acid rain. Sodium carbonate, magnesium carbonate, zinc carbonate and copper carbonate also react with acids: they fizz when in contact with acids, and the carbon dioxide released can be detected using limewater.
Cement = heat + powdered limestone + clay.
Mortar = cement + sand + water (used for joining bricks)
Concrete = cement + sand + water + agregate.
