In a lab, .0092 moles of Cu were reacted with .0046 miles of S. What would happen to the mole Cu/mole S ratio if some of the copper was unreacted (increase, decrease, stay the same)?

Also, what will happen to the mole Cu/ Mole S ratio if unreacted sulfur remains in the crucible when the final weighing is made (increases, decreases, stays the same)?
