Find the mass of a log. Burn the log until it turns to ash and smoke. Find the mass of the ash.
The correct answer is:
Find the mass of a piece of paper. Tear the paper into smaller pieces. Find the mass of the pieces.
The procedure that could be used to demonstrate that matter is conserved during a chemical change or reaction is as follows:
1. Find the mass of a piece of paper.
2. Tear the paper into smaller pieces.
3. Find the mass of the pieces.
4. Compare the mass of the original paper to the combined mass of the torn pieces.
This experiment shows that even though the paper has changed form, the total mass remains the same, indicating the conservation of matter.
To demonstrate that matter is conserved during a chemical change or reaction, you can use the procedure of finding the mass of a substance before and after the change.
For example, in option 1, you would find the mass of a piece of paper, tear the paper into smaller pieces, and then find the mass of the pieces. If the mass before tearing the paper is equal to the mass after tearing it, it demonstrates that matter is conserved during the process.
Similarly, in option 2, you would find the mass of a stick of butter, heat it until it melts, and then find the mass of the melted butter. If the mass before heating the butter is equal to the mass of the melted butter, it shows that matter is conserved during the melting process.
Likewise, in option 3, you would 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. If the mass before the reaction is equal to the mass of the resulting water and salt, it demonstrates that matter is conserved during the chemical reaction.
Finally, in option 4, you would find the mass of a log, burn it until it turns to ash and smoke, and then find the mass of the ash. If the mass before burning the log is equal to the mass of the resulting ash, it shows that matter is conserved during the combustion process.
By comparing the masses before and after the chemical changes or reactions, you can determine if matter is conserved, demonstrating the principle of conservation of matter.
