Question

Balance the following chemical equation.

CCl4 →_______ C +_________ Cl2

(Fill in the blanks with either 1,0,or 2)

Answer 1

So we have on the left 4 Cl and 1 C. We don't need to change the C on the right, but we need 4x as many Cl, so add a 4 in front of that. The balanced equation will be CCl4 --> C+ 4Cl.  

Answer 2

Answer: $CCl_{4} \rightarrow 1 C + 2Cl_{2}$

Explanation:

An equation that constitute equal number of atoms on both reactant and product side is known as a balanced chemical equation.

For example, $CCl_{4} \rightarrow C + Cl_{2}$

Number of atoms on reactant side are as follows.

C = 1

Cl = 4

Number of atoms on product side are as follows.

C = 1

Cl = 2

To balance this equation we will multiply $Cl_{2}$ by 2 on product side.

Hence, the balanced chemical equation will be as follows.

                $CCl_{4} \rightarrow C + 2Cl_{2}$
