Find the mass of the pieces. Find the mass of a piece of paper. Tear the paper into smaller pieces. Find the mass of the pieces. Find the mass of a stick of butter. Heat the butter until it melts. Find the mass of the melted butter. Find the mass of a stick of butter. Heat the butter until it melts. Find the mass of the melted butter. 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. 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.

The correct procedure that could be used to demonstrate that matter is conserved during a chemical change or reaction is to find the mass of an acid and a base, combine them to produce water and a salt, and then find the mass of the water and salt. This experiment demonstrates conservation of mass because the total mass of the reactants (acid and base) should be equal to the total mass of the products (water and salt) if matter is conserved.
