Question

If 3 moles of chlorine gas are reacted with excess sodium iodide, how many moles of I2 will be formed? (balance first!)

Cl2+ NaI → NaCl + I2

Answer 1

3 moles of I2 will be formed from 3 moles of chrlorine gas.

Explanation:

This is because, when you balance the given equation it allows for the mole ratio between the two given elements to be 1:1 so therefore 3 moles of chlorine gas will produce 3 moles of I2.
