Maintain a separate notebook titled “My Book 2 Answer Corrections.” Write the original wrong answer, the correct answer, and a personal note (e.g., “Fool! Remember – redox half equations in acid use H+, not OH-.”) Correct Answer: ΔH_f = [2ΔH_c(C) + 3ΔH_c(H₂)] -
Given enthalpy changes of combustion for C, H₂, and C₂H₅OH, calculate the enthalpy of formation of ethanol. Correct Answer: ΔH_f = [2ΔH_c(C) + 3ΔH_c(H₂)] - ΔH_c(C₂H₅OH) Why the answer matters: The algebraic manipulation is the hardest part. The answer key shows the cycle diagram and the algebraic sum .
