Hydrogen has one of the highest energy density values per mass. Its energy density is between 120 (33.333kWh) and 142 MJ/kg (39.444kWh). This means that for every 1 kg of mass of hydrogen, it has an energy value of 120-142 MJ. It is highly flammable, needing only a small amount of energy to ignite and burn. Hydrogen burns cleanly. When it is burned with oxygen, the only by products are heat and water.

∙ 12y agoTechnically, the energy is not produced - it is changed from one form to another.
Hydrogen-1 has a molar mass of 1.00795; thus, 1 kg of hydrogen has 1 / 1.007825 = 0.99224 moles.
Every 4 atoms of hydrogen will combine into one helium; thus, in the end result there will be 0.99224 / 4 = 0.24806 moles.
Helium has a molar mass of 4.0026. Thus, the 0.24806 moles will have a mass of 0.99288 kg. The difference in mass is 1 kg minus 0.99288 kg = 0.00712 kg.
Multiplying this by c2, you get an equivalent mass of 0.00712 x (3 x 108)2 = about 6.4 x 1014 joules.

In the process of fusion the sun process energy how?
In nuclear fusion, you take 4 atoms of hydrogen, and fuse them into helium. The resulting atom has less mass then the 4 atoms combined. That loss of mass is what we gets as energy. How much energy you may ask? E = mc2.
How do stars produce huge amounts of energy?
Stars produce so much energy because of nuclear reactions occuring in their core. Hydrogen atoms are smashing together and fusing into helium through a process known as nuclear fusion which releases huge amounts of energy.
Why do think the heat of vaporization for water is so much larger than the heat of fusion?
Fusion is the process of joining two elements together to make a heavier element (as in the hydrogen bomb). The energy released by fusion is fare larger than the energy required to vaporise water - the two processes just can not be equated. I suspect you have your question muddled up.
What is the difference between a fission reactor and a fusion reactor?
In simplest terms, nuclear fission involves splitting atoms apart to make energy. Fusion involves smashing atoms together to make energy. Fusion reactors are currently entirely theoretical and do not exist. The main problem with fusion is figuring out how to get more energy out of the process than you put into making the fusion happen. Right now, the sun is the only place where fusion takes place on any meaningful scale.Another Answer:From a power production point of view, i.e. a controlledreaction, it is true that we have not been successful with fusion power. However, from a weapons point of view, i.e. an uncontrolled reaction, we have been successful. This is the basis of the hydrogen bomb. Interestingly, the hydrogen bomb requires so much energy to set it off that we use a fission bomb (the original atomic bomb) to initiate the fusion reaction.
What is the element used in fusion?
Fusion experiments and designs for fusion reactors generally focus on hydrogen, in the forms of deuterium (hydrogen-2) and/or tritium (hydrogen-3). It should be born in mind that there is not much preventing any atom of any natural element undergoing fusion with something else. In fact, virtually all of what is around us is either hydrogen or something made by fusion, and this includes all the heavy elements like lead uranium.
How would you make as much heat as the sun produces?
The process of fusion. The sun makes heat by fusing hydrogen atoms. Hydrogen is the lightest element, and in the process of fusion, the lighter the element being fused, the more energy (heat) is produced.
How much energy released by the sun during nuclear fusion of 1 gram of hydrogen?
Fusion of 1 g of hydrogen would generate 6.4 × 1018 erg.
What reaction creates much of the energy given off by the sun?
Hydrogen fusion. The hydrogen atoms in the core of the sun are under such intense pressure that they combine to form helium and energy.
What causes hydrogen fusion to release so much energy?
AnswerIf you mean in the sun, then the answer is: A nuclear cycle, now known as the carbon-nitrogen-oxygen (CNO) cycle, in which hydrogen nuclei could be burned using carbon as a catalyst.If you mean in hydrogen bombs, then the answer is:Energy released in the primary stage is transferred to the secondary (or fusion) stage. The exact mechanism whereby this happens is unknown. This energy compresses the fusion fuel and sparkplug; the compressed sparkplug becomes critical and undergoes a fission chain reaction, further heating the compressed fusion fuel to a high enough temperature to induce fusion, and also supplying neutrons that react with lithium to create tritium for fusion. Generally, increasing the kinetic energy of gas molecules contained in a limited volume will increase both temperature and pressure.AnswerHydrogen fusion releases so much energy because there is so much energy available. When two hydrogen nuclei fuse to form one helium nucleus, the total energy in the helium nucleus (E=MC2) is less than the total energy in two hydrogen nuclei. The difference is the amount of energy released in the fusion reaction.
How much power is produced during nuclear fusion?
To get an exact answer, you would have to specify a fusion reaction; different reactions will produce different amounts of energy. However, to get a rough idea, the energy produced is in the order of a million times more than the typical chemical reaction.
Hydrogen or carbon fusion reactions require the highest temp?
Carbon fusion requires much higher temperatures and pressures than ordinary hydrogen fusion.
Process that is the source of the suns energy?
The Sun's energy comes from nuclear fusion where hydrogen is slammed together with so much force that 4 hydrogen atoms will fuse together to form one helium atom. Nuclear fusion releases incredible amounts of heat energy. Other larger stars fuse the heavier elements when they collapse and then explode. This is called a super nova.
Hydrogen fuel cells combine hydrogen and oxygen to produce water and energy Assume 1 kg of fuel is used and the mass of the water produced is 1.10 x 10-11 kg How much energy is produced by this fuel?

How much energy per gram of hydrogen is produced when hydrogen gas is being burned?
The combustion heat of hydrogeh (HHV) for 1 g is 141,8 kJ.
What elements in the sun are fused together?
Our sun produces mostly helium by fusion, but it also uses fusion to make lithium, beryllium and boron. Temperature and mass determine how far a star can go with fusion. "Solar fusion" only refers to the fusion going on in Sol, the star nearest Earth (our star, the sun). Stellar nucleosynthesis is how elements are produced in stars, and in much larger & hotter stars fusion is responsible for elements as heavy as unstable zinc, or stable iron.
Compare and contrast fusion and fission?
With nuclear fission, a large atomic nucleus (such as a uranium nucleus) breaks apart into smaller nuclei, and energy is released. With nuclear fusion, small atomic nuclei (such as hydrogen) join to become larger nuclei, and energy is released. Fusion of hydrogen releases much more energy than any other type of either fusion or fission. Note that the dividing line between heavy nuclei and light nuclei is the iron nucleus, which is at the perfect point of nuclear stability, so that neither fusion nor fission of iron nuclei would release any energy.
