For example: calcium carbonate + hydrochloric acid → carbon dioxide + calcium chloride + water. CaCO3 + 2HCl → CO2 + CaCl2 + H2O. Since limestone is mostly calcium carbonate, it is damaged by acid rain. Sodium carbonate, magnesium carbonate, zinc carbonate and copper carbonate also react with acids: they fizz

Limestone is quarried in open pits or in underground mines. Drilling and blasting produce a rubble that is hauled to a plant where it is crushed and screened for size to produce lime. To make lime, crushed limestone is heated in a kiln to 2,000 °F in a process called calcination ("lime-burning"), which drives off carbon dioxide,
