Answer: The mole ratio of oxygen to pentane for the combustion of pentane is 8 : 1.
Explanation: The given reaction is a type of combustion reaction.
Combustion reaction is a reaction in which a hydrocarbon reacts with oxygen gas to produce water and carbon dioxide gas.
For the reaction of pentane with oxygen, the balanced equation would be:
[tex]C_5H_{12}+8O_2\rightarrow 5CO_2+6H_2O[/tex]
In the reaction, 1 mole of [tex]C_5H_{12}[/tex] reacts with 8 moles of [tex]O_2[/tex] gas.
Thus giving us the mole ratio as
Oxygen : Pentane = 8 : 1
