Best Answer

This depends on how much hexane was being burned and how much oxygen was present.

Because the complete combustion of carbon involves placing two moles of oxygen on one mole of carbon plus the formation of water, you would need 19 moles of diatomic oxygen for every one mole of hexane.

1 C6H14 + 19 O2 --> 6 CO2 + 7 H2O

Why is hexane burned?

Hexane is only burned when it is used as an additive in gasoline. Hexane is highly flammable and can cause an explosion so there is only 1 percent to 3 percent of hexane in the total volume of gasoline. Hexane is a chemical used as a solvent to make vegetable oil from various sources, like soybeans.

What is a balanced chemical equation of if hexane combusts in the presence of oygen to form carbon dioxide and water?

Yes*. The empirical equation for this reaction is: 2C6H14 + 19O2 ---> 12CO2 + 14H2O. * n-Hexane, burned in an Iron III-catalyzed environment of pure oxygen gas, is oxidized completely. Intermediate products, such as peroxides are formed but the final products are carbon dioxide and water.

What is the black solid that is formed in the combustion of hexane?

Coke, most likely. Coke is the carbonaceous residue left over from the thermal "cracking" of hydrocarbons (the term is also used to describe the residue left over from coal combustion).


How can you calculate the amount of carbon dioxide emitted from the burning of an object?

To calculate the amount of carbon dioxide emitted from burning an object, you need to know the carbon content of the object and use the stoichiometry of the combustion reaction. The general equation for the combustion of carbon is C(s) + O2(g) -> CO2(g). By balancing the equation and knowing the amount of carbon in the object, you can calculate the amount of CO2 produced.


How many moles of carbon dioxide are produced when 84.4 moles of hexane is burned?

Balanced equation first, 2C6H14 + 19O2 >> 12CO2 + 14H2O 84.4 moles hexane (12 moles CO2/2 moles C6H14) = 506.4 moles of CO2
