Question

Methane, CH4, burns in oxygen gas to form water and carbon dioxide. What is the correct balanced chemical equation for this reaction?

A) CH4 + O --> H2O + CO2

B) CH4 + 40 --> 2H2O + CO2

C) CH4 + O2 --> H2O + CO2

D) CH4 + 2O2 --> 2H2O + CO2

Answer 1

D. CH4 + 2O2 → 2H2O + CO2

Answer 2

The correct balanced chemical equation which occur when methane burn in oxygen gas is

CH4 + 2O2 --> 2H2O +CO2 (answer D)

when methane is burned in presence of oxygen gas it produces carbon(IV) oxide and water and energy,that is 1 mole of CH4 reacted with 2 moles of O2 to form 2 moles of water and 1 mole of CO2 and enegy. This energy make the methane to be used as fuel.
