Question

The complete combustion of ethanol, C2H5OH(l), to form H2O(g) and CO2(g) at constant pressure releases 1235 kJ of heat per mole of C2H5OH.

Write a balanced equation for this reaction.
Express your answer as a chemical equation. Identify all of the phases in your answer.

Answer 1

Complete combustion means the substance is burnt in unlimited supply of Oxygen therefore carbon dioxide and not carbon monoxide is produced.

Balanced Equation

C2H5OH(l) + 3O2(g) —> 3H2O(g) + 2CO2(g)
