Question

Which gas is produced when coal burn in air

Answer 1

when coal is burnt in the presence of air ,the oxygen molecules in the air react with th coal and produces carbon dioxide gas(co2).

Answer 2

Answer:

Carbon dioxide( $co_{2}$ )i.e is released into the air when coal is burned.

When coal is burned with air present, carbon combines with oxygen gas to form ($co_{2}$).

Explanation:

• Burning coal produces energy and carbon dioxide gas.
• Energy is released during coal combustion because the chemical connection holding the carbon atoms in place is destroyed. However, additional chemical processes also take place that lead to the release of a variety of air pollutants, including sulphur dioxide, nitrogen oxide, volatile organic compounds, ash, and a variety of heavy metals, which cause air pollution and harm to human health.
• Hence in the process of burning coal in the air, majorly carbon dioxide is released.
