What compound is produced from the oxidation and combustion of organic materials like coke?

The correct answer is carbon dioxide. When organic materials like coke undergo oxidation and combustion, they react with oxygen in the air. The process of combustion generates heat and energy while producing carbon dioxide as a primary byproduct. This occurs because the carbon in coke combines with oxygen to form carbon dioxide.

Understanding this process is crucial in mine ventilation, as carbon dioxide can accumulate in confined spaces, posing respiratory hazards. Effective ventilation systems aim to dilute and remove carbon dioxide to ensure safety and maintain air quality for mine workers.

The other compounds listed do not arise from the combustion of organic materials like coke in the same way. Oxygen is consumed during the combustion process, while hydrogen and methane might be produced through different chemical reactions but are not direct products of coke combustion.
