Question

Which coefficient of O2 is needed to balance the equation C3H8 + O2 → 3CO2 + 4H2O?

Answer 1

c.) 5

Step-by-step explanation:

Answer 2

5

Step-by-step explanation:

Count the number of moles of O in the product side:

3x2 + 4

= 10

Divide it by 2 since O exists as diatomic molecule (O2)

10/2 = 5

Therefore, the coefficient required is 5.
