Balance the equation for the complete chlorination of C₂H₆. If a coefficient of "1" is required, choose "blank" for that box. C2H6 + Cl2 → C2Cl6 + HCl
help please

The balanced equation is :

Explanation:

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.

Since number carbon atom are same o both sides , we will balance hydrogen and chlorine atoms.

Step 1 : Write 6 in front of HCl, to balance hydrogen atom on both sides

Step 2 : Write 6 in front of , to balance chlorine atom on both sides.

The given chemical equation can be written in a form of balanced chemical equation as :
