Problem

Combustion of ethanol proceeds according to C2H5OH(l)+3 O2(g)→2 CO2(g)+3 H2O(l).\text{C}_2\text{H}_5\text{OH}(l) + 3\,\text{O}_2(g) \rightarrow 2\,\text{CO}_2(g) + 3\,\text{H}_2\text{O}(l). Explain why this reaction is considered a redox process. Identify which element undergoes oxidation and which undergoes reduction based on oxidation-number changes.
