If all the limiting reactant Mx2 molecules were used up, how many MX3 molecules would constitute the theoretical yield of according to the balanced equation representing the reaction? Explain your answer

To answer this question, we need the balanced equation representing the reaction and the stoichiometry of the reaction.

Let's assume the balanced equation for the reaction is:
2Mx2 + 3Y → 4MX3 + Z

According to this equation, 2 Mx2 molecules react with 3 Y molecules to produce 4 MX3 molecules.

If all the Mx2 molecules are used up, it means that they are completely converted into MX3 molecules.

Therefore, the theoretical yield of MX3 molecules would be 4 times the number of Mx2 molecules present initially.
