Question

Explain how to balance the chemical equation and classify its reaction type.

Answer 1

Answer: The balanced chemical equation is given below.

Explanation:

Every balanced chemical equation follows law of conservation of mass.

Law of conservation of mass states that mass can neither be created nor be destroyed but it can only be transformed from one form to another form.

This also means that total mass on the reactant side must be equal to the total mass on the product side.

The balanced chemical equation follows:

$2C_5H_5+Fe\rightarrow Fe(C_5H_5)_2$

On reactant side:

Number of carbon atoms = 10

Number of hydrogen atoms = 10

Number of iron atoms = 1

On product side:

Number of carbon atoms = 10

Number of hydrogen atoms = 10

Number of iron atoms = 1

Hence, the balanced chemical equation is given above.
