Question

If 3.0 moles of X and 4.0 moles of Y react according to the hypothetical reaction below, how many moles of the excess reactant will be left over at the end of the reaction?

X + 2 Y ---> XY2

2.0 mol X left over

1.0 mol X left over

2.0 mol Y left over

1.0 mol Y left over

Answer 1

1 mole of x is left over...
y is the mimiting reagent here.

Answer 2

Yup

Answer 3

look, the equation says...
2 moles of y react with 1 mole of x

so 4 moles of y will react with how much moles of x??
