Hydrogen

attraction forces are between atoms or molecules. From the strongest to the weakest, the four types of intermolecular forces used in a molecule that can affect the boiling/melting points of a solid or liquid are London dispersion, dipole-dipole, hydrogen bonds, and ionic bonds. The first and weakest of the intermolecular forces that can affect the boiling/melting points of an element or chemical is the London dispersion force. These forces, proposed by Fritz London, were caused by the…

shiny silver Magnesium ribbon can be seen, and there is no more bubble, the reaction is over. After placing the evaporating dish on a hot plate on a scale of 7, by the data from Data table #2, the white liquid that contains Magnesium, Chlorine and Hydrogen start to release fumes. As time passed, the liquid start bubble, and the liquid start to become…

example: Highly pure silicon for computer chips is produced through a displacement reaction. In this reaction, hydrogen reacts with silicon tetrachloride to form hydrogen chloride and release silicon. 4. Double displacement reactions: Double displacement reactions are those in which two compounds exchange ions to form two new compounds. For example: In the reaction of copper sulphate and hydrogen sulphide, copper sulphide and sulphuric acid are…

changes in the number of neutrons in the nucleus. Some examples of isotopes are Protium, Deuterium, and Tritium, which are all Hydrogen atoms. Instead of the zero neutrons Hydrogen has in its Protium form, Deuterium and Tritium have two and three neutrons respectively. This change in neutron number and therefore atomic weight classify these atoms as isotopes of the element Hydrogen. An ion is an atom with a charge due to changes in the number of electrons (negatively charged particles) in the…

Chemistry, oh chemistry! Chemistry is an interstmig subject. Withourt it we would not know many of the thigns we do today. However, with chemistry comes a lot of studying and hard work. There are three bonds in chemistry ionic, covalent, and hydrogen. Do not ask me why they named them this because I am unble to tell you this. However I can tell you that SCl2 is an ionic bond and NaCl is a covalent bond. Well, that is that the atoms in them form those types of bonds. Hard to belive I know, but…

These bonds occurs when a hydrogen atom is bonded to oxygen, nitrogen, and fluorine atom of another molecule, or when a hydrogen atom is electrostatically attracted to a lone pair of electrons on oxygen, nitrogen, or fluorine atom of another molecule.Therefore this essay aims at exploring the relationships between the literature…

Mn2+ Divide into two half reactions. Identify the element that is being oxidized and the other being reduced. (Use the entire ion or molecule.) Step 2 Oxidation: S2-  S0 Reduction: MnO4-  Mn2+ Balance all the elements (other than oxygen and hydrogen). Step 3 Oxidation: S2-  S0 Reduction: 8H+ + MnO4-  Mn2+ + 4H2O Balance O and H. The oxidation requires neither O nor H, but the reduction equation needs 4H2O on the right and 8H+ on the left. Step 4 Oxidation: S2-  S0 + 2e- Reduction:…

inducing an increase in sensitivity to oxidative DNA damage through an ER-mediated mechanism [78]. Evidence for a one-electron oxidation of estradiol to its reactive phenoxyl radical intermediate is presented. The phenoxyl radical metabolite abstracts hydrogen from reduced glutathione generating the glutathione thiyl radical [79, 80].…

Freshwater creek is a freshwater stream located in North Cairns, and flows through the Redlynch area-which consists of rainforest, housing, farming and recreational areas. In order to have an indication of general health levels for Freshwater creek, measurements of the water parameters must be regularly checked. This is done to maintain health and prevent abnormal water qualities. Certain water qualities like dissolved nitrates, ammonia and oxygen will be measured at a site upstream from…

temperature. Water is a compound containing 2 hydrogen atoms, but also has an oxygen molecule as well this means it has the molecular formula of H2O. The relative atomic mass of water is around 18 with “11.188% being hydrogen and 88.182% being oxygen” [1]. When bonded it forms a covalent bond, “each hydrogen atom shares an electron with the oxygen atom” [2] but these electrons are not held in equilibrium. An oxygen atom attracts the electrons more than the hydrogen atom. This is because of the…
