4450 kJ of energy would be released.
That will vary widely, depending on the type of fuel.
methane is a greenhouse gas .. it locks the sun's energy in the atmosphere
Methane is very flammable; oxygen is not flammable but as an oxidant is necessary for burning.
It is not clear what you mean by 'trap'. It contains chemical energy which can be released by burning, giving 55.5 MJ per kg. You may however be referring to the ability of the substance to absorb heat, i.e. its heat capacity. This is the amount of energy absorbed when the temperature of the substance increases by 1 degree Kelvin. This is 2.087 kJ/kgK at 200 K. (It varies a little with temperature.)
Carbon dioxide (CO2) is a greenhouse gas that is primarily released through human activities such as the burning of fossil fuels and deforestation. It is the main contributor to long-term climate change. Methane (CH4) is another potent greenhouse gas, but it is released in smaller quantities. However, methane is much more effective at trapping heat in the atmosphere, so it has a higher warming potential per unit compared to CO2.
890 kJ of energy are released when I mole of methane (16 g) is completely burned in oxygen.
That will vary widely, depending on the type of fuel.
When burning magnesium the light shines much brighter... so much to the point where it can blind your eyes if you look directly at it while burning... on the other hand methane can be observed while being lit and it wont mess up your sight in other words it is NOT nearly as bright!

The combustion of methanol to form products of H2O and CO2 do not have as much of an energy change compared to methane and a result methanol releases less energy compared to methane. The more negative an enthalpy change is, the more heat it is going to release.
How much energy do we get form analerob fermntation of wet organinc byproducts, containing fat, suger and protein
the temprature change tells t=you how much energy is being greated
One third of coal's energy reaches the consumer.
First of all, burning requires the presence of oxygen, which is not much available in outer space. Also, burning / combustion is generally endothermic process and it requires heat.
