Question 27

Propan-1-ol, C3H7OH\text{C}_3\text{H}_7\text{OH}C3​H7​OH, burns completely in a plentiful supply of oxygen. The products are carbon dioxide and water.

What is the correctly balanced equation for this reaction?

[1]
A

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}2C3​H7​OH+9O2​→6CO2​+8H2​O

B

C3H7OH+4O2→3CO2+4H2O\text{C}_3\text{H}_7\text{OH} + 4\text{O}_2 \rightarrow 3\text{CO}_2 + 4\text{H}_2\text{O}C3​H7​OH+4O2​→3CO2​+4H2​O

C

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}2C3​H7​OH+10O2​→6CO2​+8H2​O

D

2C3H7OH+8O2→6CO2+8H2O2\text{C}_3\text{H}_7\text{OH} + 8\text{O}_2 \rightarrow 6\text{CO}_2 + 8\text{H}_2\text{O}2C3​H7​OH+8O2​→6CO2​+8H2​O
