To find the total mass of the products in the reaction:
\[ \text{CaCO}_3 \rightarrow \text{CO}_2 + \text{CaO} \]
we start with the mass of the reactant, calcium carbonate (CaCO₃).
1. **Determine the mass of calcium carbonate (CaCO₃)**: We have 25 grams of CaCO₃.
2. **Understand the conservation of mass**: According to the law of conservation of mass, the mass of the reactants must equal the mass of the products. Thus, when CaCO₃ decomposes into carbon dioxide (CO₂) and calcium oxide (CaO), the total mass of the products will equal the mass of the calcium carbonate that was originally heated.
Therefore, the total mass of the products is the same as the mass of the reactant:
\[
\text{Total mass of products} = \text{mass of CaCO}_3 = 25 \, \text{grams}
\]
Thus, the total mass of the products when 25 grams of calcium carbonate is heated is **25 grams**.
