Question

When CH4 burns in limited O2, it produces

Answer 1

Answer:

When methane (CH4) burns, it reacts with oxygen gas to produce carbon dioxide and water. The unbalanced equation for this reaction is CH4(g)+O2(g)-->CO2(g)+H2O(g) This type of reaction is referred to as a complete combustion reaction.

Answer 2

When CH₄ burns in limited O₂ it produces Carbon monoxide and water.

• The reaction of methane with air is known as a combustion reaction.
• This reaction is dependent on the amount of oxygen gas supplied.
• When insufficient or limited oxygen is present incomplete oxidation of methane takes place and the product formed is carbon monoxide and water
• The reaction is represented as -

CH₄ + O₂(limited) ---------> CO + H₂O

• Carbon monoxide gas is poisonous and can lead to death
• For complete combustion of methane, methane and oxygen should be in the ratio of 1:2.
• The complete oxidation of methane is represented as -

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

• The above reaction is exothermic.Hence methane is also used as fuel.

When Ch₄ Burns In Limited O₂ It Produces Carbon Monoxide And Water.
