If 10.00 moles of copper are reacted with 6.00 moles of sulfur according to the following balanced equation, which reactant is the limiter and how many moles of excess reactant would remain after the reaction is completed? 2 Cu + S --> Cu2S Cu is limiting and 1.00 mole of excess S remain

S is limiting and 1.00 moles of excess Cu remain

S is limiting and 4.00 moles of excess Cu remain

Cu is limiting and 4.00 moles of excess S remain
