When propane is reacted in the presence of oxygen gas, the products of this combustion reaction are:

Rationale

CO2 + H2O are the products of propane combustion in the presence of oxygen.

When propane (C3H8) combusts with oxygen, the reaction typically produces carbon dioxide (CO2) and water (H2O), representing complete combustion. This reaction releases energy and is a fundamental process in energy production and combustion chemistry.

A (C + H2) YOUR ANSWER

This choice suggests that elemental carbon and hydrogen gas are produced. However, during the complete combustion of propane, the primary products are carbon dioxide and water, not elemental forms. Partial combustion could yield carbon and hydrogen, but that is not the case in a well-oxygenated environment.

B (CH2 + H2O) YOUR ANSWER

This option indicates the formation of methylene (CH2) alongside water. While CH2 could theoretically form in certain reactions, it is not a product of the complete combustion of propane. Instead, complete combustion results in CO2 and H2O, making this choice incorrect.

C (CO2 + H2) YOUR ANSWER

This selection implies that carbon dioxide and hydrogen gas are produced. While CO2 is a correct product of propane combustion, hydrogen gas is not typically produced in this reaction. Instead, water (H2O) is formed, which is the result of hydrogen atoms combining with oxygen during the combustion process.

D (CO2 + H2O) CORRECT

This choice correctly identifies the products of the complete combustion of propane when reacted with oxygen. The reaction generates carbon dioxide and water, reflecting the full utilization of propane and oxygen in the combustion process.

Conclusion

The complete combustion of propane with oxygen results in the production of carbon dioxide and water, which are the correct products of this reaction. While other choices present incorrect products or suggest incomplete combustion processes, the combination of CO2 and H2O accurately represents the expected outcome in a fully oxygenated environment. Understanding these products is essential for applications in energy, chemistry, and environmental science.

When propane is reacted in the presence of oxygen gas, the products of this combustion reaction are:

CO2 + H2O are the products of propane combustion in the presence of oxygen.
