Steam methane reforming
H2O+CH4 --> CO + 3H2
Heat of reaction
20.6 kJ/mol
Reaction of combustion of methane will give off lot of energy. In any combustion reaction there will always be formation of water vapor and heat. Methane + oxygen = combustion reaction.
Let's think about what happens in the combustion of methane. Take natural gas for example (methane) used to heat homes, or used in stoves. The product is heat, therefore heat is given off. Therefore EXOTHERMIC.
Yes, if methane gas is added to steam at 600 degrees Celsius in a combustion chamber, the methane can combust to further raise the temperature of the steam. This process can yield more heat energy and increase the overall temperature of the system.
Yes, the conversion of steam to water is an exothermic process. When steam condenses into water, it releases heat energy to the surroundings. This heat energy is given off as the steam loses its kinetic energy during the phase change.
When methane is burned, it reacts with oxygen to form carbon dioxide and water. This process releases energy in the form of heat and light, making it an exothermic reaction. The formation of the stronger bonds in carbon dioxide and water releases more energy than is required to break the bonds in methane and oxygen.

The nuclear reaction creates heat. The heat is used to create steam and run a steam generator.

Exothermic chemical reactions release energy in the form of heat and sometimes light. A common example would be the combustion (oxidation) of methane*:Methane: CH4 + 2O2 -----> CO2 + 2H2O + Energy (heat and light)* The combustion of methane (natural gas) is commonly used to heat water, cook, and to heat homes.
Burning release heat, the molecular structure of methane is destroyed and the bonding energy is released.
I assume this is the reaction you are talking about:CH4 + H2O (g) --> CO(g) + 3H2(g)From thermodynamics you can approximate the standard heat of reaction Hrxn with Hess' Law. This is the sum of the heats of formations of the products minus the sum of the heats of formations of the reactants in their stoichemtric ratios.Hrxn = SUM [(3)*Hf (H2)+(1)*Hf(CO)] - SUM [(1)*Hf (CH4) + (1)*Hf(H2O (g))]Looking up these values in a Chemical Engineering Handbook or textbook we can substitue and find the heat of reaction.Hrxn = SUM [(3)*(0 kJ/mol) + (1)*(-110.52 kJ/mol)] - SUM [(1)*(-74.85 kJ/mol) +(1)*(-241.83 kJ/mol)]= -110.52 - (-316.68) kJ/mol= + 206.16 kJ/mol, therefore the reaction is endothermicRemember standard heats of formation of elements, as hydrogen in this case, are zero.

Yes, the conversion of steam to water is an exothermic process. When steam condenses into water, it releases heat energy to the surroundings. This heat energy is given off as the steam loses its kinetic energy during the phase change.
An exothermic reaction is a reaction with release of heat. As an example the burning reaction of methane: CH4 + 2 O2 ------→ CO2 + 2 H2O
Heat from the nuclear reaction changes water to steam.
In exothermic reactions heat is liberated. So reaction can be reactants---->products+heat
When methane is burned, it reacts with oxygen to form carbon dioxide and water. This process releases energy in the form of heat and light, making it an exothermic reaction. The formation of the stronger bonds in carbon dioxide and water releases more energy than is required to break the bonds in methane and oxygen.
