Alkanes — practice question

Which equation shows the complete combustion of butane, $\text{C}_4\text{H}_{10}$?

  • A$2\text{C}_4\text{H}_{10} + 5\text{O}_2 \rightarrow 8\text{C} + 10\text{H}_2\text{O}$
  • B$2\text{C}_4\text{H}_{10} + 9\text{O}_2 \rightarrow 8\text{CO} + 10\text{H}_2\text{O}$
  • C$2\text{C}_4\text{H}_{10} + 13\text{O}_2 \rightarrow 8\text{CO}_2 + 10\text{H}_2\text{O}$
  • D$\text{C}_4\text{H}_{10} + 4\text{O}_2 \rightarrow 4\text{CO}_2 + 5\text{H}_2$
