Answer 1

The best procedure to demonstrate that matter is conserved during a chemical change or reaction is:

Find the mass of an acid and a base. Combine them to produce water and a salt. Find the mass of the water and salt.

This procedure shows a chemical reaction where two substances react to form new substances, and measuring the total mass before and after the reaction can demonstrate that mass is conserved. The total mass of the reactants should equal the total mass of the products, illustrating the principle of conservation of matter in a chemical change.
