The procedure that could be used to demonstrate that matter is conserved during a chemical change or reaction is:
Find the mass of a piece of paper. Tear the paper into smaller pieces. Find the mass of the pieces.
This procedure involves measuring the mass of a paper before tearing it into smaller pieces, and then measuring the mass of the torn pieces. By comparing the mass before and after the tearing process, you can determine if matter is conserved during the physical change of tearing. If the mass before and after tearing is the same, it indicates that matter is conserved and that the tearing process did not result in any loss or gain of mass.
Similarly, the other options provided (finding the mass of water and salt after combining an acid and a base, finding the mass of melted butter after heating, and finding the mass of ash after burning a log) also demonstrate the conservation of matter during chemical changes or reactions.
