Question

Select the coefficients necessary to balance each equation. Choose a coefficient for every compound.

Answer 1

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
