Question

Write the balanced chemical equations for the following reactions and identify the type of reaction:

Limestone is heated strongly to form quicklime and carbon dioxide gas is evolved

Answer 1

Decomposition reaction is a type of chemical reaction in which a single compound breaks down into two or more elements or new compounds.Calcium carbonate or limestone decomposes into calcium oxide and carbon dioxide when heated and the reaction is used to make quicklime and carbon dioxide gas.

${CaCO}_3\left(s\right)\stackrel{heat}{\to }CaO\left(s\right)+{CO}_2\left(g\right)\uparrow$
