What is the chemical equation combustion of ethanol?
I believe the balanced chemical equation isC2H5OH+3O2 ---> 2CO2+3H2O the amount of energy relased from the equation is -1409kJ/molhowever I tried to calculate it out myself with a bond energy table i received from my professor and ended up with the number -1283kJ/mol...close enough

How many compounds are in 3H2O?
3 Hydrogen atoms, 2 Oxygen atoms.
What is 9/2o2?
For example, if you have the formula C3H6 + 9/2O2 --> 3CO2 + 3H2O, then usually it's a reduced balanced equation to find the (delta)H (standard molar enthalpie) of a molecule, which in this case would be for the C3H6. To find the original balanced equation, just multiply everything by 2 (since the denominator of 9/2 is 2). It should be C3H6 + 9/2O2 --> 3CO2 + 3H2O to 2C3H6 + 9O2 --> 6CO2 + 6H2O. I hope this helps
