One procedure that could be used to demonstrate the conservation of matter during a chemical change is the measurement of mass before and after the reaction.
Steps:
1. Set up a balance or a scale and calibrate it to ensure its accuracy.
2. Measure and record the mass of the reactants before the reaction.
3. Mix the reactants in a container and allow the reaction to occur.
4. After the reaction, measure and record the mass of the products.
5. Compare the mass of the reactants to the mass of the products.
6. If mass has remained constant or is within a close range of the initial mass, it can be concluded that matter is conserved during the chemical change. If there is a significant difference, it indicates that matter has not been conserved.
7. Repeat the experiment multiple times to ensure accuracy and reliability of the results.
