Answer:
The balanced chemical equation provided is:
\[ C_3H_8 + 3O_2 \rightarrow 3CO_2 + 4H_2O \]
From the equation, we can see that 1 mole of propane (C3H8) reacts with 3 moles of oxygen (O2). Therefore, to calculate the number of moles of oxygen required to react completely with 5.34 moles of propane (C3H8), we use the mole ratio from the balanced equation.
Given that 1 mole of propane requires 3 moles of oxygen, we set up a proportion:
\[ \frac{5.34 \text{ moles of propane}}{1} = \frac{x \text{ moles of oxygen}}{3} \]
Solving for \( x \):
\[ x = \frac{5.34 \times 3}{1} = 16.02 \text{ moles of oxygen} \]
So, 16.02 moles of oxygen are necessary to react completely with 5.34 moles of propane.
