Question

hydrochloric acid and sodium hydroxide can be combined to form sodium chloride and water. which best explains the reaction?
the mass of sodium hydroxide will result in the same mass of sodium chloride.
the total mass of hydrochloric acid and sodium hydroxide will result in a lower total mass of sodium chloride and water.
the mass of hydrochloric acid will result in the same mass of sodium chloride.
the total mass of hydrochloric acid and sodium hydroxide will result in the same total mass of sodium chloride and water.

Explanation:

This is based on the law of conservation of mass. In a chemical reaction like the one between hydrochloric acid and sodium hydroxide, the total mass of reactants equals the total mass of products.

Answer:

The total mass of hydrochloric acid and sodium hydroxide will result in the same total mass of sodium chloride and water.
