Final answer:
The coefficient for CO2 in the balanced equation is 16.
Step-by-step explanation:
The coefficient for CO2 in the balanced equation is 16.
To balance the equation, you need to ensure that there are an equal number of each type of atom on both sides of the equation. In this case, the unbalanced equation is:
C5H8(l) + O2(g) → ? CO2(g) + H2O(g)
In the balanced equation, the coefficient for CO2 is 16, which means that 16 molecules of CO2 are formed as a product of the reaction.
