In a chemical reaction, the law of conservation of mass states that the total mass of the reactants must equal the total mass of the products. In this case, you are starting with 30 grams of calcium carbonate (CaCO3).
According to the reaction:
\[ \text{CaCO}_3 \rightarrow \text{CO}_2 + \text{CaO} \]
The total mass of the products will also be 30 grams, because no mass is lost or created in the reaction.
Therefore, the correct response is:
**30 grams**
According to the reaction:
\[ \text{CaCO}_3 \rightarrow \text{CO}_2 + \text{CaO} \]
The total mass of the products will also be 30 grams, because no mass is lost or created in the reaction.
Therefore, the correct response is:
**30 grams**
