Answer 1

The procedure that could be used to demonstrate that matter is conserved during a chemical change or reaction is to find the mass of an acid and a base, combine them to produce water and a salt, and find the mass of the water and salt.

This setup allows you to clearly observe a chemical reaction and measure the mass of the reactants (the acid and the base) and the products (water and salt) to show that the total mass remains constant, demonstrating the conservation of matter.
