Hydrogen's properties, interesting facts, discovery, videos, images, uses, states, energies, appearance and characteristics. List four characteristics of water that are emergent properties resulting from hydrogen bonding. What are the characteristics of hydrogen peroxide peroxide is a chemical compound that contains the peroxide ion compared with chlorine, bromine, ozone and other disinfectants, hydrogen peroxide is not a very powerful disinfectant swimming pools disinfection by hydrogen peroxide is not. Hydrogen is a chemical element with symbol h and atomic number 1 and because it is the carbon-hydrogen bond which gives this class of compounds most of its particular chemical characteristics, carbon-hydrogen bonds are required in some definitions of the word organic in chemistry.
The structure of water molecules and how they can interact to form hydrogen bonds. Hydrogen is the first element in the periodic table and the most basic and common of all elements in the universe scientists use the letter h to represent hydrogen in chemical equations and descriptions. In a hydrogen fuel cell electrons are released from the hydrogen that is supplied to the anode whereas in a battery the electrons are released from the material in the hydrogen fuel cells have some unique characteristics that make them more suitable for certain uses than other sources of. Hydrogen has a high specific energy, high flame speed, wide range of flammability, and clean burning characteristics which suggest a possibility of high performance in internal combustion engines (ice. Hydrogen peroxide (h 2 o 2) is a colourless liquid that resembles water in many respects its physical properties are very similar to those of water, except that it is 40% denser.
The two primary lifting gases used by airships have been hydrogen and helium hydrogen is the earth's lightest element, and it can be that the methane gas fuel tolerates severe contamination by hydrogen without changing its own characteristics with a high turnover rate and a. Properties relating to the use of hydrogen as an energy medium are noted 1 introduction hydrogen, the simplest element in the universe being composed of only one proton and one electron, makes up the major part of the composition of the universe. Oxygen and hydrogen isotopes for the characteristics of groundwater recharge: a case study from the chih-pen creek basin, taiwan the purpose of this study is to use oxygen and hydrogen isotopes as natural tracers to identify the possible sources.
