Answer:

First balance the equation

C2H6 + 7/2O2 2CO2 +3H2O

for one mole of C2H6 there are 7/2 mole of O2 required. so for4.50 moles you require 4.50 x 7/2 = 15.75 moles of O2.

The study of the chemical and bonds is called chemistry.

The correct answer is 15.75 moles.

What is the balanced reaction?

  • The balanced reaction is defined as the number of atoms present equally on both sides of the reactant and the product.

The balanced equation is as follows:-

[tex] C_2H_6 +\frac{7}{2} O_2-----> 2CO_2 +3H_2O [/tex]

One mole of C2H6 there is 7/2 mole of O2 required.

Hence, For 4.50 moles you require is as follows:-

[tex] 4.50 * \frac{7}{2} = 15.75[/tex]moles of O2.

Hence, the correct answer is 15.75.
