of Fuel By R.J. Kita Hydrogen is the lightest and most basic element known to man. With its simple structure comprised of only one proton and one electron‚ it is one of the major constituents of all hydrocarbon based fuels. By studying the response of hydrogen with respect to magnetic fields and the accompanying increased energy output‚ much can be learned and applied to other related fuels. In the oxidation/combustion of hydrocarbon fuels‚ it is the outer shell of the hydrogen that is combusted first

Energy: Nuclear Fusion‚ Hydroelectric‚ and Hydrogen Fuel Cells In today’s world‚ where everyone owns an electronic appliance‚ energy is an extremely valuable resource and in high demand. Though in the past this energy was provided by burning fossil fuels such as coal and natural gas‚ this way of providing energy can’t last much longer due to the dwindling amount of fossil fuels and the damage it causes to the environment. Therefore‚ scientists have been searching for new ways of providing energy

substances is called chemical equation. Example: In this equation‚ A and B are called reactants and C and D are called the products. Arrow shows the direction of chemical reaction. Condition‚ if any‚ is written generally above the arrow. When hydrogen reacts with oxygen‚ it gives water. This reaction can be represented by following chemical equation. In first equation words are used and in second symbols of substances are used to write the chemical equation. For convenience‚ symbol of substance

The universe is made up of 93.5% of Hydrogen atoms‚ 6.3% of Helium and 0.2% of other elements. By looking at the spectrum of hot stars‚ upper solar atmosphere and solar wind‚ an abundance of Helium is determined. Only from the 1920s there were methods of calculating what elements were present in a gas by just observing its spectrum‚ due to the fact that different elements absorb and emit different wavelengths of light. (2) Gamow thought that nuclear fusions took place in the first minutes after
