The correct procedure that could be used to demonstrate that matter is conserved during a chemical change or reaction is:
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.
To perform this procedure, you would need to measure the mass of both the acid and the base separately using a balance. Then, mix them together and allow them to react. After the reaction is complete, separate the resulting water and salt from any remaining solution or impurities. Finally, measure the mass of the water and the salt separately using the balance again.
By comparing the initial mass of the acid and base with the final mass of the water and salt, you can determine if matter is conserved. If the masses remain the same, it shows that matter has been conserved during the reaction.

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.
