The procedure that could be used to demonstrate that matter is conserved during a chemical change or reaction is: Find the mass of a stick of butter, heat the butter until it melts, and then find the mass of the melted butter.
To demonstrate that matter is conserved during a chemical change or reaction, you can use the following procedure:
1. Find the mass of a sample before the reaction.
2. Perform the chemical change or reaction.
3. Find the mass of the products after the reaction.
The correct procedure in this case would be:
Find the mass of a log. Burn the log until it turns to ash and smoke. Find the mass of the ash.
By comparing the mass of the log before burning with the mass of the ash produced after burning, you can determine if matter is conserved. If matter is conserved, the mass of the ash should be equal to (or very close to) the mass of the log.
This procedure is based on the law of conservation of mass, which states that mass is neither created nor destroyed during a chemical reaction.
