In a rocket motor filled with butane, how many

\mathrm{kg}

of liquid oxygen should be provided for each

\mathrm{kg}

of butane for its complete combustion?

\mathrm{C}_4 \mathrm{H}_{10}+13 / 2 \mathrm{O}_2 \rightarrow 4 \mathrm{CO}_2+5 \mathrm{H}_2 \mathrm{O}

View answer and explanation

Correct option: A

4 kg

The correct answer is 4 kg because it represents the amount of liquid oxygen needed for complete combustion of 1 kg of butane based on the stoichiometry of the balanced chemical equation.
