The procedure that best demonstrates 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 experiment illustrates the principle of conservation of mass because it involves a chemical reaction where the reactants (acid and base) are transformed into products (water and salt). If you measure the combined mass of the reactants before the reaction and compare it to the combined mass of the products after the reaction, you should find that they are equal, thereby demonstrating that matter is conserved in the chemical process.
