What does law of Conservation of Mass say about a chemical reaction?
GPT 3.5
The law of Conservation of Mass states that in a chemical reaction, the total mass of the reactants must be equal to the total mass of the products. This means that no mass is created or destroyed during a chemical reaction, but rather it is rearranged or transformed. In other words, the number and types of atoms in the reactants must be the same as the number and types of atoms in the products. This law is based on the principle that atoms are neither created nor destroyed in a chemical reaction, but are merely rearranged to form new compounds.
