Question

Assertion (A): Burning of Natural gas is an endothermic process.

Reason (R) : Methane gas combines with oxygen to produce carbon dioxide and water.​

Answer 1

Explanation:

Assertion is false but Reason is true

Answer 2

The assertion is false but the reason is true.

• Methane (CH₄) is the major component of natural gas.
• It is used as a fuel in motors and industries since the burning of natural gas is an exothermic process and a large amount of heat energy is released.
• Methane gas reacts with oxygen to produce carbon dioxide and water as shown:

        CH₄ + 2 O₂  --> CO₂ + 2 H₂O + Heat

• The carbon dioxide produced is a greenhouse gas that causes global warming. Hence, the use of natural gas is harmful to the environment.
