Propan-1-ol, C3H7OH\text{C}_3\text{H}_7\text{OH}C3H7OH, is a primary alcohol commonly used as a solvent in the pharmaceutical industry. When propan-1-ol undergoes complete combustion in excess oxygen, carbon dioxide and water are produced.
Which equation for this reaction is correctly balanced?
2C3H7OH+9O2→6CO2+8H2O2\text{C}_3\text{H}_7\text{OH} + 9\text{O}_2 \rightarrow 6\text{CO}_2 + 8\text{H}_2\text{O}2C3H7OH+9O2→6CO2+8H2O
C3H7OH+5O2→3CO2+4H2O\text{C}_3\text{H}_7\text{OH} + 5\text{O}_2 \rightarrow 3\text{CO}_2 + 4\text{H}_2\text{O}C3H7OH+5O2→3CO2+4H2O
2C3H7OH+10O2→6CO2+8H2O2\text{C}_3\text{H}_7\text{OH} + 10\text{O}_2 \rightarrow 6\text{CO}_2 + 8\text{H}_2\text{O}2C3H7OH+10O2→6CO2+8H2O
C3H7OH+9O2→3CO2+4H2O\text{C}_3\text{H}_7\text{OH} + 9\text{O}_2 \rightarrow 3\text{CO}_2 + 4\text{H}_2\text{O}C3H7OH+9O2→3CO2+4H2O
