Benzene, C6H6, reacts with oxygen, O2, to form CO2 and
H2O. How much O2 is required for the complete
combustion of 1.0 mol C6H6?
Thank you for the opportunity to help you with your question!
2C6H6 + 15O2 ---> 12CO2 + 6H2O
from the balanced equation, the ratio between any 2 substances can be determined by taking the coefficients in front of each. for example, the ratio between Oxygen and propane is 15 : 2, which means there are 15 moles of O2 required to completely react with 2 mole of C6H6.
if 2 moles of C6H6 can be combusted using 15 moles of O2,then 1 mole of C6H6 will combusted using 7.5 moles of O2
Why can the equation not be C6H6 + 15O2 -> 6CO2 + 3 H2O, thank you very much!
the no. of oxygen is not well on both sides...you have 30 on the left side then 12+3=15 on the right
