Ethаnоl, C2H5OH, is being prоmоted аs а clean fuel and is used as an additive in many gasoline mixtures. Calculate the ΔH°rxn for the combustion of ethanol. (ΔH°f [C2H5OH(l)] = –277.6 kJ/mol; ΔH°f [CO2(g)] = –393.5 kJ/mol; ΔH°f [H2O(g)] = –241.8 Write out your calculations and answers clearly, with all numbers labeled correctly, on a piece of paper. Right after submitting your exam, upload your photos to the Assignment Box, "Calculations for Exam 4 (Chapter 5 and 6)"
