The substances on the right and left of the chemical equation have the same:energy.tempereature.total mass.quality.state.

The substances on the right and left of the chemical equation have the same total mass. This is based on the Law of Conservation of Mass, which states that matter cannot be created or destroyed in an isolated system. Therefore, the total mass of the reactants (substances on the left of the equation) must equal the total mass of the products (substances on the right of the equation).

The energy, temperature, quality, and state of the substances can change during a chemical reaction. For example, an exothermic reaction releases energy into the surroundings, so the products would have less energy than the reactants. Similarly, the state of the substances can change, such as when liquid water evaporates into steam. The quality of the substances can also change, as new products are formed with different properties. The temperature can change as well, as it is often used to control the rate of the reaction.
