Question

When a compound containing c, h, and o is completely combusted in air, what reactant besides the hydrocarbon is involved in the reaction? express your answer as a chemical formula. identify the phase in your answer?

Answer 1

A special type of combination is combustion. One of the key reactants in a combustion reaction must always involve an oxygen. This is the defining characteristic of combustion. When a combustible matter is burned, it reacts with the oxygen in air in the presence of heat. Moreover, one of its end products must be water. Let's take glucose as our example of a hydrocarbon.

C6H12O6(s) + 6O2(g)  -----> 6CO2 (g) + H2O(g)

Therefore, when a solid glucose interacts with oxygen gas, it yields carbon dioxide and water vapor.

Answer 2

When a compound containing c, h, and o is completely combusted in air, the reactant besides the hydrocarbon that is involved in the reaction is, O2(g).

Hydrocarbons burn in air to form water and carbon dioxide as the only products.

Further Explanation  

Hydrocarbons  

• Hydrocarbons are types of compounds that are mostly made up of hydrogen and carbon elements. However other hydrocarbons are made up of carbon, hydrogen and oxygen elements.
• The major types of hydrocarbons include, alkanes, alkenes, alkynes, alcohols, and alkanoic acids.  
• Alkanes are saturated hydrocarbons while alkenes and alkynes are unsaturated hydrocarbons containing only carbon and hydrogen atoms.  
• Alcohols and alkanoic acids contains hydrogen, oxygen and carbon atoms.

Combustion of Hydrocarbons  

• Hydrocarbons burn in air to form carbon dioxide and water as the only products.

That is;

For hydrocarbons with carbon and hydrogen

• CxHy + O2(g) = CO2(g) + H2O(g)  

For the compound containing carbon, hydrogen and oxygen  

• CxHyOn + O2 = CO2(g) + H2O(l)

Examples  

Propane which is an alkane burns in air to form water and mineral salt.

C3H8(g) + O2(g) = CO2(g) + H2O(l)

Ethanol is a hydrocarbon in the homologous series of alcohols. It burns in air to form carbon(IV)oxide and water.

C2H5OH(l) + 3O2(g) = 2CO2(g) + 3H2O(l)
