Potassium chloride is used as a substitute for sodium chloride for individuals with high blood pressure. Identify the limiting reactant and determine the mass of the excess reactant remaining when 7.00 g of chlorine gas reacts with 5.00 g of potassium to form potassium chloride.

* Limiting reagent: potassium.

Explanation:

Hello,

In this case, the undergoing chemical reaction is:

In such a way, the reacting moles of chlorine are:

Now, the amount of chlorine gas that would react with 5.00 g of potassium result:

Thus, the chlorine will be in excess and the potassium will be the limiting reagent. Therefore, the mass of excess chlorine turns out:

Best regards.
