Question

Which procedure would could be used to demonstrate the matter of concern during a chemical change or reaction

Answer 1

One procedure that could be used to demonstrate the matter of concern during a chemical change or reaction is the use of a balance to measure the mass of the reactants before the reaction and the mass of the products after the reaction. By comparing the mass of the reactants to the mass of the products, one can observe if there is any change in the amount of matter during the reaction, indicating a chemical change has occurred.
