Answer 2

Explanation:

15 .Therefore, the amount of the atoms in each element does not change in the chemical reaction. ... A balanced chemical equation occurs when the number of the atoms involved in the reactants side is equal to the number of atoms in the products side.

16.When cuprous oxide is heated with cuprous sulphide, copper metal is obtained. - In this reaction, SO2 gas is released as byproduct with its peculiar smell.
