Octane (C8H18) is a component of gasoline that burns according to the equation: What

QUESTION:

Octane (\(\mathrm{C}_{8} \mathrm{H}_{18}\)) is a component of gasoline that burns according to the equation:

\(\mathrm{C}_{3} \mathrm{H}_{6} \mathrm{O}(l)+4 \mathrm{O}_{2}(g) \rightarrow 3 \mathrm{CO}_{2}(g)+3 \mathrm{H}_{2} \mathrm{O}(g)\)

\(\Delta H_{r x n}=-1790 k J\)

What mass of octane (in g) is required to produce \(1.55 \times 10^{3} \mathrm{~kJ}\) of heat?

Equation Transcription:

C8H18

1.55  103 kJ

Text Transcription:

C_8H_18

C_3H_6O(l)+4O_2(g) rightarrow 3CO_2(g)+3H_2O(g)

Delta H_rxn=-1790kJ

1.55  times 10^3 kJ
