Question

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

Answer 1

Step-by-step explanation:

The given reaction is as follows.

`Ca + Cl_(2) \rightarrow CaCl_(2)`

The number of elements on reactant side are as follows.

• Ca = 1
• Cl = 2

The number of elements on product side are as follows.

• Ca = 1
• Cl = 2

Therefore, the equation is completely balanced.

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