Answer : To calculate the standard molar enthalpy of complete combustion of liquid ethanol can be done by using the formula given below;
Now, the enthalpies of the elements in their standard state is zero always.
So the
Here we can avoid the heat of enthalpy of oxygen,carbon dioxide and water as they exists in their standard states.
So the
= 
Now, the enthalpies of the elements in their standard state is zero always.
So the
Here we can avoid the heat of enthalpy of oxygen,carbon dioxide and water as they exists in their standard states.
So the
