The oxygen atoms
Answer this question… Carbon, hydrogen, oxygen
The general chemical equation for the combustion of oil or petroleum is: [ \text{Hydrocarbon} + O_2 \rightarrow CO_2 + H_2O ] Where the hydrocarbon represents the various components found in oil or petroleum, such as octane (C8H18).
To balance the combustion equation for pentanediol (C5H12O2), you start with the unbalanced equation: C5H12O2 + O2 → CO2 + H2O. After balancing the carbon, hydrogen, and oxygen atoms, the balanced equation is: C5H12O2 + 6 O2 → 5 CO2 + 6 H2O. Therefore, the coefficient of O2 in the balanced equation is 6.
In a hydrocarbon combustion reaction, carbon (C) atoms should be placed first, followed by hydrogen (H) atoms, and then oxygen (O) atoms. This order reflects the typical stoichiometry of combustion, where carbon is oxidized to form carbon dioxide (CO₂) and hydrogen is oxidized to form water (H₂O). The balanced equation will ultimately show the relationships among these elements in the reaction.
The oxygen atoms
Hydrogen atoms are typically balanced last when balancing hydrocarbon combustion reactions because they are usually the most abundant and straightforward to adjust. It is best to first balance the carbon atoms, then the hydrogen atoms, and finally the oxygen atoms in the reaction.

After balancing a hydrocarbon combustion reaction equation, you often notice that the number of atoms of each element on the reactant side equals the number of atoms of that element on the product side. The coefficients in the balanced equation represent the ratio of moles of each reactant and product involved in the reaction. The balanced equation also helps in determining the stoichiometry of the reaction and the amount of reactants needed or products formed.
apex sometimes the coefficient for the oxygen molecule is not a whole number.
The balanced symbol equation for the complete combustion of a hydrocarbon fuel like octane (C8H18) is: C8H18 + 12.5O2 -> 8CO2 + 9H2O

In a combustion reaction of a hydrocarbon like methane (CH4) with oxygen, carbon dioxide (CO2) and water (H2O) would be produced. The balanced chemical equation for this reaction would be CH4 + 2O2 → CO2 + 2H2O.
The correct answer is: C5H12 + 8O2 5CO2 + 6H2O.
