The balanced equations, that include the appropriate stoichiometric coefficients, are:
C₂H₆ + 3.5 O₂ ⇒ 2 CO₂ + 3 H₂O
C₂H₂ + 2.5 O₂ ⇒ 2 CO₂ + H₂O
We have 2 combustion reactions. We will balance them using the trial and error method.
1. We have the following unbalanced equation.
C₂H₆ + O₂ ⇒ CO₂ + H₂O
First, we will balance C atoms by multiplying CO₂ by 2.
C₂H₆ + O₂ ⇒ 2 CO₂ + H₂O
Then, we will balance H atoms by multiplying H₂O by 3.
C₂H₆ + O₂ ⇒ 2 CO₂ + 3 H₂O
Finally, we will get the balanced equation by multiplying O₂ by 3.5.
C₂H₆ + 3.5 O₂ ⇒ 2 CO₂ + 3 H₂O
2. We have the following unbalanced equation.
C₂H₂ + O₂ ⇒ CO₂ + H₂O
First, we will balance C atoms by multiplying CO₂ by 2.
C₂H₂ + O₂ ⇒ 2 CO₂ + H₂O
Finally, we will get the balanced equation by multiplying O₂ by 2.5.
C₂H₂ + 2.5 O₂ ⇒ 2 CO₂ + H₂O
The balanced equations, that include the appropriate stoichiometric coefficients, are:
C₂H₆ + 3.5 O₂ ⇒ 2 CO₂ + 3 H₂O
C₂H₂ + 2.5 O₂ ⇒ 2 CO₂ + H₂O
