Question

When the equation fe+c12 fec13 is balanced what is the coefficient for c12?

Answer 1

Answer: The coefficient of
`Cl_2` in the given equation is 3

Step-by-step explanation:

A balanced chemical equation always follow law of conservation of mass.

This law 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 number of individual atoms on reactant side must be equal to the total number of individual atoms on the product side.

The balanced chemical equation for the given reaction follows:

`2Fe+3Cl_2\rightarrow 2FeCl_3`

By Stoichiometry of the reaction:

2 moles of iron reacts with 3 moles of chlorine gas to produce 2 moles of iron (III) chloride

Hence, the coefficient of
`Cl_2` in the given equation is 3

Answer 2

1) Equation:


`Fe+Cl_2-\ \textgreater \ FeCl_3`

2) Balanced equation:


`2Fe+3Cl_2-\ \textgreater \ 2FeCl_3`

3) The coefficient for Cl2 is 3.<------ answer
