Answer

Explanation:

Step1: Identify reactant - product concept

Reactants are substances that start a chemical reaction, products are what is formed.

Step2: Analyze the reaction

The text says calcium bicarbonate ($CaH_2C_2O_6$) breaks down. So it is a reactant. Calcium carbonate ($CaCO_3$) and carbon dioxide ($CO_2$) are formed, so they are products.

Answer:

Substance Reactant Product
calcium bicarbonate ($CaH_2C_2O_6$) $\checkmark$
calcium carbonate ($CaCO_3$) $\checkmark$
carbon dioxide ($CO_2$) $\checkmark$
