Octane, $\text{C}_8\text{H}_{18}$, is a hydrocarbon that burns by combustion in a petrol engine. $\ldots w\,\text{C}_8\text{H}_{18} + \ldots x\,\text{O}_2 \rightarrow \ldots y\,\text{CO}_2 + \ldots z\,\text{H}_2\text{O}$ Which row contains the numbers required to balance the equation?
- A$w=1, x=8, y=8, z=9$
- B$w=1, x=17, y=8, z=9$
- C$w=2, x=16, y=8, z=9$
- D$w=2, x=25, y=16, z=18$
