Methane and oxygen are stable compounds and require a specific amount of energy known as activation energy to react with each other. This energy can never be reached at the room temperature and that is why methane does not react with oxygen at room temperature.
Does no oxygen react at room temperature?
Hence, the reaction between NO and oxygen is fast whereas the reaction between CO and oxygen is slow.
What happens when methane is burnt in air?
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.
When methane is completely combusted in oxygen?
The atoms of one element are the same as atoms of another element. When methane is completely combusted in oxygen forming carbon dioxide and water, how does the mass of the reactant gases compare to the products? The masses of the reactants and products are equal.
What is the chemical equation for methane burning in oxygen?
Methane (CH4) ( C H 4 ) burns in oxygen to produce carbon dioxide and water vapor. The balanced equation is: CH4+2O2→CO2+2H2O C H 4 + 2 O 2 → C O 2 + 2 H 2 O .
Is methane burning in oxygen endothermic or exothermic?
The combustion reaction between methane and oxygen is exothermic and using the data provided this can be shown through a calculation.
How much energy is released when 1000g of methane are burned?
The molar mass of methane is 16 g/mole, so burning methane will release (810 kJ/mole) / (16g/mole) = about 51 kJ/g fuel burned. since three moles of CO2 are produced for each mole of C3H8 burned, burning propane will release 677 kJ/mole of CO2 released.

Is energy released when bonds are broken?
Breaking and making bonds
Energy is absorbed to break bonds. Bond-breaking is an endothermic process. Energy is released when new bonds form.
