Allisa [31]

Answer:

E. Substance A will be the limiting reactant.

Explanation:

Below is a generic equation for a reaction.

2A + 3B → C + 3DA

According to the balanced equation, the theoretical molar ratio of A to B is 2:3, that is, 2 moles of A react with 3 moles of B.

<em>If I mix 2 units of A, with 6 units of B, which of the following is true?</em>

<em>A. There would be no reaction.</em> FALSE. The reaction will occur until the limiting reactant is over

<em>B. Both reactants will fully react.</em> FALSE.

<em>C. Not enough information given.</em> FALSE.

<em>D. Substance B will be the limiting reactant.</em> FALSE. Substance B will be the reactant in excess because there are 6 moles and only 3 moles are required.

<em>E. Substance A will be the limiting reactant.</em> TRUE.
