Which procedure could be used to demonstrate that matter is conserved during a chemical change or reaction?

Answer 1

One procedure that could be used to demonstrate the conservation of matter during a chemical change or reaction is to carefully measure the mass of all the reactants and products involved before and after the reaction. This can be done using a balance or scale. By comparing the mass of the reactants to the mass of the products, if they are found to be equal, it can be concluded that matter is conserved during the chemical change or reaction.
