Question

Explain ionic balancing with an example?

Answer 1

See Below

Explanation:

In order for an equation to be balanced, both sides must have an equal number of each element. Take for example, the reaction between Magnesium Chloride (`MgCl_2`) and Water (`H_2O`).
`MgCl_2 + H_2O -> MgO + HCl`

First count the number of each element on either side.

Left:
`Mg -> 1`
`Cl -> 2`
`H -> 2`
`O -> 1`

Right:
`Mg -> 1`
`Cl -> 1`
`H -> 1`
`O -> 1`

To balance, we write the coefficient required to balance the number of elements on each side.

`MgCl_2 + H_2O -> MgO + 2HCl`

The equation is now balanced.
