Question

1. a scientist studies the following chemical equation for the production of water. 2h₂ + o₂ → 2h₂o. what happens to the mass of the reactants during this chemical reaction? mass of hydrogen increases mass of oxygen decreases mass of hydrogen doubles mass of oxygen stays the same

Explanation:

In a chemical reaction, mass is conserved according to the law of conservation of mass. Reactants are consumed to form products. In the given reaction \(2H_2 + O_2
ightarrow2H_2O\), hydrogen and oxygen react to form water. As the reaction proceeds, the mass of the reactants (hydrogen and oxygen) decreases as they are used up to make the product (water).

Answer:

mass of oxygen decreases
