Question

if a chemical reaction occurs in a closed system (no way for any part of the reaction to escape), how does the product mass compare to the reactant mass? it depends on the type of reaction the mass would decrease the mass would stay the same the mass would increase

Explanation:

Step1: Recall the Law of Conservation of Mass

The Law of Conservation of Mass states that in a closed system, mass is neither created nor destroyed during a chemical reaction. So the total mass of reactants equals the total mass of products.

Step2: Apply the Law to the Problem

The system is closed (no mass escapes), so the mass of products should be equal to the mass of reactants.

Answer:

the mass would stay the same
