Question

conservation of mass
the chemical reaction shown above takes place in a closed system. what is true about the system while the reaction occurs?

Explanation:

Step1: Recall conservation of mass principle

In a closed - system chemical reaction, mass is conserved. The total mass of reactants equals the total mass of products.

Step2: Analyze given reaction

The reactants are \(2CH_4 + 4O_2\) and the products are \(2CO_2+4H_2O\). The number of each type of atom (C, H, O) is the same on both sides of the equation. The total mass of the substances in the system remains constant as atoms are just rearranged during the reaction.

Answer:

The total mass of the system remains constant.
