Question

When chlorine reacts with sodium iodide, sodium chloride and iodine are produced. The balanced equation for this reaction is:

Answer 1

Cl2 + NaI -> NaCl + I2

We are unbalanced with Chlorine and Iodine so we can do this:

Cl2 + 2NaI -> 2NaCl + I2

Reactants: Cl = 2, Na = 2, I = 2

Products: Cl = 2, Na = 2, I = 2

So we are balanced.
