What is the order of reaction of combustion of methane?

CH4(g)+2O2(g)→CO2(g)+2H2O(g)

Where does the energy come from in a combustion reaction?

Chemical energy stored in the bonds of molecules is transformed into heat and light energy. Most chemical reactions are of this type and thus are exothermic. Less energy is required to break old bonds than is given off in the process of forming new bonds.

What is the physical state of methane at room temperature?

gas
Methane is a gas at standard conditions. However, at low temperature and/or high pressures the gas becomes a liquid or a solid. The methane phase diagram shows the phase behavior with changes in temperature and pressure.

When 16 g of methane reacts with 64 g of oxygen to give carbon dioxide and water then which of the following statement is correct?

D. 16g of methane reacts with 64g of O2 to give 44g of CO2 and 36g of water. Complete answer: > In this reaction we can see that one mole of methane reacts with two moles of oxygen, one mole of carbon dioxide and two moles of water so option A is correct and also option B is correct.

Is combustion of methane spontaneous?

The reaction is not spontaneous, however, since the methane-oxygen mixture is stable indefinitely until a spark or flame initiates the reaction.

How much energy is released in the combustion of methane?

890.4 kilojoules
When methane gas is combusted, heat is released, making the reaction exothermic. Specifically, the combustion of 1 mol of methane releases 890.4 kilojoules of heat energy.

What is combustion reaction formula?

Meaning of Combustion Reaction The usual equation for a complete combustion reaction is CH4 + O2 → CO2 + H2O.

Can methane be liquefied?

Methane cannot be condensed to a liquid by pressure at ordinary temperatures because the critical temperature3 of methane is −82.1 ºC. Above this temperature no liquid phase exists.

What temperature does methane become a gas?

The boiling point of methane is −162 °C (−259.6 °F) and the melting point is −182.5 °C (−296.5 °F). Methane in general is very stable, but mixtures of methane and air, with the methane content between 5 and 14 percent by volume, are explosive.

Which of the following equations correctly shows that the combustion of methane is an exothermic reaction?

The combustion of methane or octane is exothermic; it releases energy. CH4 + 2 O2 → CO2 + 2 H2O + energy The energies of the products are lower than the energiies of the reactants.

Which of the following equations correctly describes the combustion of CH4 and O2 to produce water H2O and carbon dioxide CO2?
