I'm not positive but I'm pretty sure its Light waves.
The limiting reagent is Copper (Cu)
First, balance the reaction before determining the limiting reactant.
Cu + 2Ag
Cu(NO3)2 + 2Ag from NO3
Take the beginning material amount and calculate the number of moles of one of the products to identify the limiting reactant. The limiting reactant is the one that produces a product with the fewest moles.
5.50×1.00/2.00=2.75
The limiting reactant is the one that is consumed first and sets a limit on the quantity of product(s) that can be produced. Calculate how many moles of each reactant are present and contrast this ratio with the mole ratio of the reactants in the balanced chemical equation to get the limiting reactant.
Copper is the limiting reactant since there are only 2.50 mol of it and only 2.50 mol of AgNO3 will result from the reaction.
