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

Answer 1

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.
