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.
