Its core product line was in mobile water treatment that allowed oil and gas exploration companies to meet government water recycling requirements at well heads and drilling sites. Unfortunately‚ the Unit had faced two failures developing its mini oxidation systems. By 2006 it was losing around $6 million annually putting the credibility of the Unit on the line. The first launch of the new generation product was aimed to provide safe drinking water to developing nations

ELECTROCHEMISTRY Terms to Know: Electrochemistry—the study of the interchange of chemical and electrical energy OIL RIG – oxidation is loss‚ reduction is gain (of electrons) Oxidation – the loss of electrons‚ increase in charge Reduction – the gain of electrons‚ reduction of charge Oxidation number – the assigned charge on an atom Oxidizing agent (OA) – the species that is reduced and thus causes oxidation Reducing agent (RA) – the species that is oxidized and thus causes reduction ELECTROCHEMISTRY INVOLVES TWO

carbonyl- containing samples were given to the group for examination. The samples were analyzed through different tests namely the involvement of the solubility of alcohols in water‚ the Lucas Test‚ the Chromic Acid Test or also known as Jones Oxidation‚ the 2‚4-Dinitrophenylhydrazone (2‚4-DNP) Test‚ the Fehling’s Test‚ the Tollens’ Silver Mirror Test‚ and the Iodoform Test. The solubility of alcohols in water test showed that the sample‚ benzyl alcohol was immiscible while ethanol was the most

Aldehydes are common in organic chemistry. Many fragrances are aldehydes. Sources of Aldehydes: a. Natural and Anthropogenic Aldehydes: Urban‚ Rural‚ and Indoor A trace amount of formaldehyde is present in the air as a result of photochemical oxidation (hydroxyl radicals) of hydrocarbons‚ for example‚ methane naturally present in the atmosphere (Atkinson‚ 1990; Riedel et al.‚ 1999). In rural air‚ terpenes and isopropene emitted by foliage also react with hydroxyl radicals to form formaldehyde (Atkinson

essential function in cell metabolism. [1] They are small‚ membrane bounded organelles that have at least fifty different enzymes for several metabolic reactions. [2] Their appearance is like lysosomes; however‚ their main function is oxidation reactions especially oxidation of hydrogen peroxide and producing oxygen and water. There are diseases related and caused by this organelle that can be classified in three groups. [2] First group is a disorder duo to overall dysfunction of peroxisomes‚ like zellweger

318); the acetyl groups are fed into the citric cycle which are oxidized to CO2 and the energy released in conserved reduced electron carriers- NADH and FADH; the high transfer potential electrons transferred to oxygen to form water in a series of oxidation-reduction reactions called oxidative phosphorylation (Tymoczko‚ p. 318). The citric acid cycle takes place in the mitochondria and is the central metabolic hub in the cell; the gateway to aerobic metabolism of all fuel molecules (Tymoczko‚ p.
