Answer: 24 moles
Explanation:
Combustion is a type of chemical reaction in which hydrocarbon is oxidized to carbon dioxide and water.
The balanced chemical reaction for combustion of butane is :
[tex]2C_4H_{10}+13O_2\rightarrow 8CO_2+10H_2O[/tex]
According to stoichiometry,
Given: Oxygen is the excess reagent. Thus butane is the limiting reagent as it limits the formation of product.
2 moles of butane gives 8 moles of carbon dioxide.
Thus 6 moles of butane will give=[tex]\frac{8}{2}\times 6=24moles[/tex] of carbon dioxide.
