Read the given chemical reaction.

C2H6 + O2 → CO2 + H2O

How many moles of O2 are required to react completely with 3.2 moles of C2H6? (5 points)

a
3.5 moles of O2

b
6.5 moles of O2

c
10.4 moles of O2

d
11.2 moles of O2

Respuesta :

Answer:

The Correct answer is D, 11.2 Moles of o2

Explanation:

The number of moles of O₂ required to react completely with 3.2 moles of C₂H₆ is 11.2 moles. The correct option is d - 11.2 moles of O2

Stoichiometry

From the question, we are to determine the number of moles of Oâ‚‚ required

First, we will balance the given chemical equation

The balanced chemical equation is

2C₂H₆ + 7O₂ → 4CO₂ + 6H₂O

This means 2 moles of C₂H₆ is required to react with 7 moles of O₂

Now,

If 2 moles of C₂H₆ is required to react with 7 moles of O₂

Then,

3.2 moles of C₂H₆ will react with x moles of O₂

x = [tex]\frac{7 \times 3.2}{2}[/tex]

x = 11.2 moles

Hence, the number of moles of O₂ required to react completely with 3.2 moles of C₂H₆ is 11.2 moles. The correct option is d - 11.2 moles of O2
