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.
The correct procedure that could be used to demonstrate that matter is conserved during a chemical change or reaction is:
1. Find the mass of an acid and a base. Combine them to produce water and a salt.
2. Find the mass of the water and salt.
This procedure allows you to measure the mass of the reactants (acid and base) and compare it to the mass of the products (water and salt). If matter is conserved, the total mass of the reactants should be equal to the total mass of the products.
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. Then, find the mass of the water and salt.
Explanation:
To demonstrate conservation of matter during a chemical change or reaction, you need to show that the total mass of the substances before the reaction is equal to the total mass of the substances after the reaction. In this procedure, you start by measuring the mass of an acid and a base. You then combine them to initiate a chemical reaction, which results in the formation of water and a salt. Finally, you measure the mass of the water and salt produced. If matter is conserved, the total mass of the water and salt should be equal to the total mass of the acid and base initially used.
By comparing the initial and final masses, you can determine if the mass has changed during the chemical reaction or if it remained the same. If the masses are equal, it provides evidence for the law of conservation of matter, which states that matter cannot be created or destroyed but only transformed from one form to another.
