Answer 1

The correct answer is Methane

Key Points

Methane is commonly found in coal mines and marshy places.
It is a colorless, odorless gas that is highly flammable and can form explosive mixtures with air.
Methane is produced by the anaerobic decomposition of organic matter.
In coal mines, methane is often referred to as "firedamp" and poses significant safety hazards due to its explosive nature.
In marshy areas, methane is generated by microbial activity in the absence of oxygen and is often released as marsh gas.

Additional Information

Methane (CH₄) is the simplest alkane and the main component of natural gas.
It is a potent greenhouse gas, with a global warming potential many times greater than that of carbon dioxide over a 20-year period.
Detecting and managing methane emissions is crucial for mine safety and environmental protection.
Technologies such as methane drainage and ventilation systems are used in coal mines to mitigate the risks associated with methane.
Efforts are ongoing to capture and utilize methane from coal mines and marshes for energy production, reducing its environmental impact.
