Balance the following equation:

C₂H₆ + 2Cl₂ => C₂H₄Cl₂ + 2HCl

Or from left to right:

1, 2, 1, 2

Explanation:

To balance an equation, start by counting the number of atoms of each element on both sides.

C₂H₆ + Cl₂ => C₂H₄Cl₂ + HCl

C  2                 C  2

H  6                 H  5

Cl  2                Cl  3

We should increase the number of hydrogen atoms (H) on the right (products).

C₂H₆ + Cl₂ => C₂H₄Cl₂ + 2HCl

C  2                 C  2

H  6                 H  6

Cl  2                Cl  4

Increase the number of chlorine atoms (Cl) on the left (reactants).

C₂H₆ + 2Cl₂ => C₂H₄Cl₂ + 2HCl

C  2                  C  2

H  6                  H  6

Cl  4                 Cl  4

The equation is now balanced because there are the same number of atoms on each side.

C₂H₆ + 2Cl₂ => C₂H₄Cl₂ + 2HCl

or, if your drop down menus need you to write "1".

1C₂H₆ + 2Cl₂ => 1C₂H₄Cl₂ + 2HCl

The correct format is not to write the "1".
