Question

What coefficient would the O2 have after balancing C4H10+ 02 → CO2 + H2O?

Answer 1

The answer should be C

Answer 2

Answer: option D. 6.5

Explanation:

C4H10 + 02 → CO2 + H2O

To balance the the above equation, add 2 in front of C4H10, 13 in front of O2, 8 in front of CO2 and 10 in front of H2O i.e

2C4H10 + 13O2 → 8CO2 + 10H2O

Next divide through by 2,we have

C4H10 + 6.5O2 → 4CO2 + 5H2O

From the above illustration, we see that the coefficient of O2 is 6.5
