Explanation:
Just remember that to balance using this method,
first look for the elements that change their oxidation number, and
later count the number of electrons that changed,
later identify which element oxidazes and which reduces and
finally cross the number of electrons that change in each semireaction and write these numbers in the main reaction.
2Cr⁺³ (aq) + 6Cl⁻ (aq) ⇒ 2Cr(s) + 3Cl₂ (g)
2 Cr 2
6 Cl 6
