You mix 5.25 moles of A with 7 moles of B in the chemical equation 3A + 4B 2C + 3D. Which statement is true about the reactants?
B has a greater molar mass than a. A has a greater molar mass than
b. B is the limiting reactant.
c. A is the limiting reactant.
d. A and B are in ideal stoichiometric proportion.
The answer is d. A and B are in ideal stoichiometric proportion. In a balanced reaction equation, the ratio of mole number of the reactants is equal to the ratio of the coefficients. 5.25:7=3:4.
