Answer 1

Answer:

Calcium carbonate is a dietary supplement used when the amount of calcium taken in the diet is not enough. Calcium is needed by the body for healthy bones, muscles, nervous system, and heart. Calcium carbonate also is used as an antacid to relieve heartburn, acid indigestion, and upset stomach.

The thermal decomposition of calcium carbonate CaCO3 produces calcium oxide CaO (a.k.a. quicklime) and carbon dioxide gas

When limestone is heated strongly, the calcium carbonate it contains absorbs heat (endothermic ) and decomposes to form calcium oxide. This is indicated by an orange glow as the limestone is heated.
