Fuels — practice question

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

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