How would you balance this equation: #C_2H_6+O_2 -> CO_2+H_2O#?
Balance H first.
There are 6 H atoms on the left and 2 on the right. Place a coefficient of 3 in front of the
Balance C next.
There are 2 C atoms on the left and 1 C atom on the right. Add a coefficient of 2 in front of the
Balance O last.
There are 2 O atoms on the left and 7 O atoms on the right.
Place a coefficient of 7/2 in front of
All of the coefficients in a chemical equation must be whole numbers. To change
There are now 4 C atoms on both sides, 12 H atoms on both sides, and 14 O atoms on both sides. The equation is balanced.
