Hydrogen storage

aqcuainted with -- elemental hydrogen (H2) and elemental nitrogen (N2). The resulting product in this reaction is the covalent compound, ammonia (NH3). Elemental hydrogen and elemental nitrogen is something one should be familiar. Of course, elemental hydrogen is in the water humans drink everyday. However, hydrogen is quite rare elsewhere on Earth because it is nearly fourteen times lighter than the air in the atmosphere, so it rapidly escapes the Earth 's gravity if unbound. Hydrogen is the…

molecules attracts the cations and by extension the water molecules around it. The more water molecules being attracted the more Hydrogen ions are being formed between them. As a result of this, there is a cluster of water molecules around the ions, therefore the ions are hydrated. Anions also attract water molecules; in this case the positive end of the molecule is where the Hydrogen atoms are being attracted to and not the negative end of the molecule. This is called Polar Molecules. Polar…

flavin, the intermediate resulted from the hydroxylation step, dehydrates at the final step to return to the oxidized flavin species to complete the catalytic cycle (7, 8). However, the uncoupled pathway, where the C(4a)-hydroperoxy flavin eliminates hydrogen peroxide without hydroxylating substrate, also as a minor path (7,…

Everything around us is made up of some substance or mass. These substances or materials can be real, solid or something that we taste, feel or even smell. The chemicals that the substances are made from generated chemical reactions. The chemical reactions that were being studied caused one famous scientist to develop a law about chemical reactions. Joseph Louis Proust was a French Chemist who came up with a law in the 18th century that governed the chemical reaction. Proust’s law or discovery…

Abstract. In this work investigation for the effect of compressed CO2 on the morphology of the produced Polyaniline (PANI) was carried out. The conventional oxidative polymerization using ammonium peroxydisulfate as oxidizing agent was used with and without compressed CO2. The results showed that different morphologies of PANI nanorods and PANI nanoparticles were produced using the conventional polymerization with and without compressed CO2 respectively. Molecular characterization of the…

Pure Copper Iodide were synthesised and the mass percentage of Copper in purified Copper (I) Iodide sample were determined by applying Beer’s Law in UV-Vis spectroscopy. Absorbance value of Cu-cuprizone solution was measured. Using the absorbance value of 0.3576 , the concentration of the Cu-cuprizone solution were obtained at 0.001389g/L with reference to the graph of the standard solution A to D. The graph of absorbance against concentration of the standard solution A to D shows a linear…

2.1. C. tomentosum extract characterization C. tomentosum extract proximal composition is shown in Table 1. The relatively higher ash proportion in seaweed extract (SE) (aprox. 74%) could largely be accounted for by the lower moisture content, and probably due to a hygroscopic nature of the SE (Blanco-Pascual, Montero, & Gómez-Guillén, 2014). The values of TPC and DPPH radical-scavenging activity are consistent with literature (Andrade et al., 2013; Valentão et al., 2010) (Table 1). POD and PPO…

Introduction and Historic Background Copper (II) chloride is often times called cupric chloride. The molecular formula is CuCl2. There are two forms of copper (II) chloride. One form is the anhydrous form, which is when the copper (II) chloride is a yellowish-brown powder. It has a boiling point around 993 degrees Celsius and a melting point near 630 degrees Celsius. If copper II chloride is in its dihydrate form, it is a green-crystalline solid. The formula weight of the dihydrate form is…

ABSTRACT: Terpolymer / kaolinite microcomposites were synthesized by 2:2:1 molar ratio of aniline, anthranilic acid and o-phenylenediamine monomers, respectively using various percentages of kaolinite clay via modified in situ oxidative ter-polymerization. The results were confirmed by FT-IR and UV-Vis absorption spectra of terpolymers / kaolinite composites. The thermal behaviour of the terpolymer and composites was studied. Terpolymers / kaolinite composites were thermally more stable than…

Comparison of Organometallic Compounds of Transition Metals and Main Group Elements Organometallic Compounds: The compounds which contain at least one direct metal to carbon covalent bond are known as organometallic compounds many of these are thermodynamically unstable and are pyrophoric. The meta may belongs to main group, transition metal, f group metal or a metalloid i.e. selenium, boron, arsenic, silicon, antimony, germanium, and tellurium and the carbon moiety may be alkyl, alkene, alkyne,…
