To demonstrate that matter is conserved during a chemical change or reaction, the most appropriate procedure would be:
**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 option involves a chemical reaction where the reactants (acid and base) result in new products (water and salt), allowing you to observe the conservation of mass by comparing the total mass before and after the reaction. The other options involve physical changes (melting, tearing) or do not capture the essence of a chemical reaction.
