Comparison of Three Isomers of Butanol SCH 4UI Abstract The Hydroxyl group on alcohols relates to their reactivity. This concept was explored by answering the question “Does each alcohol undergo halogenation and controlled oxidation?” . Using three isomers of butanol; the primary 1-butanol‚ the secondary 2-butanol and the tertiary 2-methyl-2-propanol‚ also referred to as T-butanol‚ two experiments were performed to test the capabilities of the alcohols. When mixed with hydrochloric acid in

uranium deposits for many years‚ but more recently has been applied to gold ore refractory and refractory concentrates. This process involves the oxidation of sulfide‚ ferrous‚ and sometimes carbon containing minerals in order to liberate the gold trapped within. This process is possible by use of several bacterial strains which gain energy from the oxidation of reduced sulfur and ferrous minerals. There are three main bioleaching techniques: heap bioleaching‚ bioreactors and vats. Optimizing the

During a race‚ there is an inherent increase in energy requirements and these requirements are maintained by the many biochemical events happening within the body. This essay explores the metabolic processes that occur at the start of the race‚ 5 minutes into the race and 45 minutes into the race in terms of mobilization‚ biochemical pathways used for degradation of molecules and comparing the yield of ATP of the two types of fuels involved‚ namely carbohydrates and lipids. Carbohydrates‚ which have

reaction or process that releases energy in the form of heat. Sometimes the term is applied to processes that release other forms of energy‚ such as electrical energy‚ sound‚ or light. An Example –The example would be combustion of wood. Oxidation - Oxidation is the loss of electrons during a reaction by a molecule‚ atom or ion. An Example - The example is iron combines with oxygen to form iron oxide or rust. The iron is said to have oxidized into rust. Heating natural gas - Natural gas is a
