The corn-rich diet of the rural South contained very little trytophan, an essential amino acid that is required for the synthesis of nicotinamide. Interestingly, corn contains substantial amounts of nicotinamide, but it must be treated with base to be absorbed. The native Mexicans soaked their corn mean in lime water, consisting of the base calcium hydroxide, when making tortillas. "lime" refers to a mixture of slaked line and quicklime. In the first reaction, sodium calcium metal reacts slowly with water to form calcium hydroxide (slaked lime) and hydrogen gas. In the second reaction, calcium carbonate decomposes with heat to calcium oxide (quicklime) and carbon dioxide. Write a balanced chemical equations for these two processes.

Line water is a mixture of slaked lime and quicklime.
The chemical formula of slaked lime is calcium hydroxide, Ca(OH)2.
The chemical formula of quick lime is calcium oxide, CaO.
