Answer:

exothermic

Explanation:

because the heat is produced from that reaction.

Combustion of methane:

  • When methane burns in the air it has a blue flame. In sufficient amounts of oxygen, methane burns to give off carbon dioxide (CO₂) and water (H₂O).
  • When it undergoes combustion it produces a great amount of heat, which makes it very useful as a fuel source.
  • Methane is a very effective greenhouse gas.

From the given chemical equation:

CH₄(g) +2O₂(g) → CO₂(g) + 2H₂O(g) + energy

Since, in the product side the energy is being released thus we can conclude that the reaction is Exothermic in nature.
