How do you balance C2H6 O2-CO2 H₂O?|化学

Here's how to balance the chemical equation for the combustion of ethane (C₂H₆):

1。不均衡な方程式を書きます：

C₂H₆ + O₂ → CO₂ + H₂O

2。炭素原子のバランス：

There are 2 carbon atoms on the left side and 1 on the right. Place a coefficient of 2 in front of CO₂:

C₂H₆ + O₂ → 2CO₂ + H₂O

3。水素原子のバランス：

There are 6 hydrogen atoms on the left and 2 on the right. Place a coefficient of 3 in front of H₂O:

C₂H₆ + O₂ → 2CO₂ + 3H₂O

4。酸素原子のバランス：

There are 2 oxygen atoms on the left and 7 on the right. Place a coefficient of 7/2 in front of O₂:

C₂H₆ + 7/2 O₂ → 2CO₂ + 3H₂O

5。 (Optional) Make coefficients whole numbers:

Multiply the entire equation by 2 to get rid of the fraction:

2C₂H₆ + 7O₂ → 4CO₂ + 6H₂O

バランスの取れた方程式はです

2C₂H₆ + 7O₂ → 4CO₂ + 6H₂O
