Is this equation balanced?

• Yes, because there is the same number of K and Cl atoms on the right as the left

• Yes, because there is a 2 on the left and a 2 on the right

• No, because there are a different number of K and Cl atoms on the right and on the left

• No, Because there are two compounds on the left and one on the right
