Readers want to know where and when the action takes place.
The question is incomplete, the complete question is;
Use the chemical reaction to answer the question. CaCO3 → CO2 + CaO A scientist heats 30 grams of calcium carbonate (CaCO3) in the chemical reaction shown. What is the total mass of the products?
A. 10 grams B. 15 grams C. 30 grams D. 60 grams
When a scientist heats 30 grams of calcium carbonate (CaCO3) in the chemical reaction, the total mass of the products is 30 grams.
According to the law of conservation of mass, mass is neither created nor destroyed in a chemical reaction.
The simple interpretation of this law is that the total mass of reactants should necessarily be the same as the total mass of products obtained in the reaction.
We had 30grams of Calcium Carbonate (CaCO3) reacting hence we must have a total mass of 30 grams of CaO and CO2 obtained after reaction.
