Answer:

b. 4

Explanation:

The reaction expression is given as:

   C₃H₈   +   O₂     →    CO₂   +  H₂O

To solve this problem, we employ a mathematical approach.

Now use coefficient a, b, c and d as the numbers that will balance the expression:

            aC₃H₈   +   bO₂     →    cCO₂   +  dH₂O

Conserving C: 3a  = c  

                   H:  8a  = 2d

                    O: 2b  = 2c + d

let a  = 1, c  = 3, d  = 4 , b  = 5

 The balanced reaction expression is:

            C₃H₈   +   5O₂     →    3CO₂   +  4H₂O
