Question

Consider the equation: A+3B=2C. If 3.0 moles of A is reacted with 6.0 moles of B, which of the following is true after the reaction is complete?
a) A is the leftover reactant because you need only 2 moles of A and have 3
b) B is the leftover reactant because you have more moles of B than A
c) A is the leftover reactant because for every 1 mole of A, 4 moles of C are produced.
d) B is the leftover reactant because 3 moles of B react with every 1 mole of A
e) neither reactant is leftover
I'm thinking a?
