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.

Which atom should be balanced last when balancing hydrocarbon combustion reactions?

When balancing hydrocarbon combustion reactions, the carbon (C) atoms should typically be balanced first, followed by the hydrogen (H) atoms, and finally, the oxygen (O) atoms should be balanced last. Balancing oxygen last is important because it often appears in both the hydrocarbon and the products (carbon dioxide and water), making it easier to adjust the coefficients to achieve balance. This systematic approach helps ensure that the reaction is correctly balanced in terms of mass and charge.


How should the combustion reaction C5H2 O2 CO2 H2O be balanced?

To balance the combustion reaction of pentadiyne (C5H2) with oxygen (O2), producing carbon dioxide (CO2) and water (H2O), you start by writing the unbalanced equation: C5H2 + O2 → CO2 + H2O. The balanced equation is: 2 C5H2 + 13 O2 → 10 CO2 + 2 H2O. This ensures that there are equal numbers of each type of atom on both sides of the equation.


Why mix molten potassium and sugar?

Mixing molten potassium and sugar can result in a highly exothermic reaction due to the high reactivity of potassium with oxygen. This reaction can release a large amount of heat and result in a rapid combustion of the sugar. It is extremely dangerous and should not be attempted as it can lead to fires, explosions, and serious injuries.

Which atom should be balanced last when balancing hydrocarbon combustuion reactions?

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.

What is the product of oxygen and a fuel?

No, oxygen is an oxidizer. Combustion reactions are oxidation-reduction reactions. The reaction could not happen without the oxidizer, but oxygen cannot be considered the fuel. The fuel is the compound which is being oxidized: i.e. Carbon oxidized to carbon dioxide.
