In a chemical equation, if 2 atoms of chlorine are used in the reactants to form calcium chloride, how many formula units of calcium chloride must be part of the products? ca + cl2 → cacl2

Explanation:

The given reaction is as follows.

The number of elements on reactant side are as follows.

The number  of elements on product side are as follows.

Therefore, the equation is completely balanced.

Thus, we can conclude that only one formula units of calcium chloride must be part of the products.

Chemical formulas of molecules of Fluorine and Chlorine are F2 and Cl2 respectively.
