Have you ever added salt to your fries to give it more flavor? The salt you added was created by the following chemical reaction:
2Na(s)+Cl2(g)→2NaCl(s)
What is the minimum amount of sodium that must be reacting with one mole of chlorine to produce the salt you add to your food?
2Na(s) + Cl2(g)→2NaCl(s)
To react with 1 mole of chlorine, we need two moles of sodium to create two moles of sodium chloride.
⇒ The minimum amount of sodium =2 moles
