Answer 3

Number of Molecules Participating in a Reaction

The number of molecules that participate in a chemical reaction is determined by the stoichiometry of the reaction. This is based on the balanced chemical equation for the reaction, which shows the ratio of reactants and products involved.

In general, the number of molecules participating in a reaction can be determined from the coefficients in the balanced chemical equation. The coefficients represent the number of molecules of each substance involved in the reaction.

For example, in the reaction:

2A + 3B → 4C

The coefficients indicate that 2 molecules of A and 3 molecules of B react to produce 4 molecules of C.

Therefore, the number of molecules participating in a reaction is directly related to the coefficients of the substances involved in the balanced chemical equation.
