Compute the amount of heat released (absolute value) when 1.1 kg of liquid ethanol is burned in excess oxygen to make carbon dioxide and liquid water
Write the equation and balance it. Look up the delta Hf values. Then
deltaHrxn = (n*deltaHf products) - (n*deltaHf reactants).
n is the coefficient for the appropriate gas you look up. Post your work if you get stuck.
