Find the standard enthalpy of formation of ethylene, C2H4(g), given the following data: heat of combustion of C2H4(g)= –1411 kJ/mol; ΔH°f[CO2(g)] = –393.5 kJ/mol; ΔH°f[H2O(l)] = –285.8 kJ/mol.

SHOW YOUR WORK Get a CLEAN piece of paper, write your name at the top. Write the question number. When {y} g of a fuel was burned in a calorimeter containing 1,000. g of water, a temperature rise of {x}°C was observed. The heat capacity of the calorimeter was 1.34 kJ/°C Calculate the enthalpy of the reaction in kJ/g fuel Enter your answer below.
