The correct answer is CaO(s) + H2O(l) = Ca(OH)2(s)
The high-temperature byproduct of calcining limestone is lime. Despite the fact that every state has limestone deposits, relatively little of it is pure enough to be used to make industrial lime. The rock must contain at least 50% calcium carbonate in order to be called limestone.
CaO(s) + H2O(l) = Ca(OH)2(s)
Describe the natural sources of lime.
Quicklime is the product of lime (about 85 percent). Lime can also be produced as a byproduct in paper mills, carbide plants, and water-treatment facilities, as well as from other calcareous materials such aragonite, chalk, coral, marble, and shell.
