mixed 10.0 moles of Ca, which is the limiting reagent?
V2O5 + 5Ca >>>> 2V + 5CaO
Could you please show the steps in your results. (TIA)

Calcium is the limiting reagent.
The reason is that it takes 5 moles of calcium to reduce each mole of V2O5 (a 5:1 ratio). Since an equal number of moles of each substance are present in the problem, we have only a 1:1 ratio and come up short on the calcium. It would take 50 moles of calcium to reduce the 10 moles of V2O5.

From your equation, each mole of V2O5 reacts with 5 mol of Ca.
So how much Ca would you need to react with 10 mol V2O5? Do you have that much?
This should give you your answer.
