Hydrogen

oxygen (65%), Carbon (18%), Hydrogen (10%), and Nitrogen (3%). It is also composed of about 28 other elements including, Potassium, Sodium, and Calcium. Each plays a major role on the daily functions of the human body. Oxygen accounts for roughly about two-thirds of the mass of the human body and is use in cell respiration. Carbon is part of the molecular structure in certain fats, proteins, and carbohydrates; which are essential for human health. Nitrogen is only about three percent of the mass of the human body and yet is the fourth most abundant element found in the physical body. Nitrogen gases are found within the lungs and contained in proteins and nucleic acids. Each…

Hydrogen is an Alkali earth metal in group 1 on the periodic table. Hydrogen has an atomic mass of 1 and an atomic number of 1. Hydrogen has 1 VALENCE electron and 1 neutron. It has 1 ring, because it’s in period 1. Hydrogens state of matter is gas. Lithium is a Alkali Earth Metal on the Periodic Table. Lithium's state or matter is solid. Lithium has a atomic number of 3 and an atomic mass of 7 when rounded. It has 1 valence electron around its nucleus and 4 neutrons in the nucleus. Lithium has…

1. Cost Analysis The production of hydrogen from fossil fuels is said to be a mature technology. Of the two main fossils fuels used, natural gas offers the best economics and efficiencies and is the main pathway used to generate hydrogen nowadays, mainly for the production of ammonia and methanol. The other, being coal, can also be used to produce hydrogen but the initial investment is much greater and the efficiency is lower compared to when natural gas is used. Coal can be economically…

The Haber process In modern society mankind relies on industrial chemistry processes. This industrial chemistry process is known as “The Haber Process” it is responsible for the production of the compound ammonia; which is accountable for the world’s consumption of natural gas (BBC, 2014). The Haber process is the method of synthesizing the compound of ammonia which is produced from Hydrogen (H2) and Nitrogen (N2) gas (Sinha, 2014). In 1909 a German named Fritz Haber developed the compound of…

awareness of climate change and global warming have enforced the so called hydrogen energy transition, which describes the significant change from the dominant oil based technologies towards the use of hydrogen as a clean fuel in transportation. Although hydrogen could be used instead of fossil fuel in combustion engines, its replacement by a fuel cell is intended. It has a higher efficiency than a combustion engine, provides electrical energy to power an electrical drive, generates water as a…

Examining Substitution Reactions of Several Alcohol-Containing Compounds Several Experiments were performed using substitutions reactions with hydrogen halides. These results and favor methods or pathways for the several alcohols were observed and will be discussed. Introduction for all the material Scheme 1. Substitution of 3-(m-tolyl)propan-1-ol to form 1-(3-bromopropyl )-3-methylbenzene. Aromatic materials used in this reaction has high boiling point thus the reaction was heated…

Chapter 2 LITERATURE SURVEY 2.1. Characteristics of Hydrogen Sulphide 2.1.1. Physical and Chemical Properties H2S is a colourless gas characterised by a rotten gas odour which is highly toxic. It is soluble in different liquids including water and alcohols. It is typically formed under deficit oxygen conditions in the presence of organic matter and sulphate compounds (WHO, 2003). Hydrogen Sulphide is also present in the atmosphere in the range of 0.0001-0.0002 ppm though it may vary with places…

Trend The constant, 0 v/v % hydrogen peroxide solution, did not react with the catalase, therefore it was recorded as 300+ seconds and had a reaction rate of 0 seconds-1. The 0.1 v/v % hydrogen peroxide concentration recorded a reaction rate of 0.17 seconds-1. The 0.2 v/v % hydrogen peroxide concentration, recorded a lower reaction rate than the 0.1 v/v% at 0.14 seconds-1. The 1 v/v % hydrogen peroxide concentration recorded higher at 0.49 seconds-1. The 3 v/v % hydrogen peroxide concentration…

Gargamelle Bubble Chamber Do you wonder what a huge tank of 12,000 liters of liquid hydrogen could be used for? The Gargamelle Bubble Chamber is a large, cylinder shaped tank/chamber. It was full of pressurised liquid hydrogen. The camber was used to detect charged particles. The chamber needed many things to work, it detected bubble paths , and it took pictures to gather evidence of charges. The chamber worked by using neutrons, particles, charged plates, cameras, and liquid hydrogen. The…

– equation (2 gives info on location of electron in terms of probability density - wave functions are called orbitals – [pic], where E is energy, e2 is electric potential, r is orbital radius and h is Planck’s constant 1925 Wolfgang Pauli – each orbital has only 2 electrons is now explained due to direction of spin of electrons. Spinning electrons create magnetic field. Only 2 electrons of opposite spin in an orbital referred to as Pauli exclusion principle Hund’s rule – half fill…
