Could anyone please give me some guidance on answering these CH1 questions please? Thank you so much
When ethanol burns in air, it produces oxygen and water.
C2H5OH+3O2-->2CO2+3H2O
1. Use the enthalpy change standard values below to calculate the standard enthalpy change for the combustion of ethanol.
C2H5OH = -278
CO2 = -394
H2O = -286
O2 = 0
2. The standard combustion enthalpy change for octane C8H18 is -5512kjmol-1.
By using this value and your answer to question 1, show that octane gives more energy for every gram of fuel burned than ethanol.
