Question

Consider the reaction 2CuCl2 + 4KI → 2CuI + 4KCl + I2. If 4 moles of CuCl2 react with 4 moles of KI, what is the limiting reactant?
a
CuCl2

b
KI

c
CuI

d
I2

Answer 1

2CuCl2 + 4KI → 2CuI + 4KCl + I2

You use 2 moles of CuCl2 and 4 moles of KI to make the products

You're starting off with 4 moles of CuCl2 and 4 moles of KI
How much of the reactants do you have left?

Answer 2

Let's re-word the question then for you to understand it
