reagents. The basis of determining an unknown hydrocarbon is due to the differences in reactions of hydrocarbons. An unknown compound is determined using tests. The unknown gives a positive result in nitration test and gives no brown precipitate in oxidation test. The unknown is an aromatic and non-alkylated compound. _______________________________________________ Introduction: Hydrocarbons are organic compounds that composed of only hydrogen and carbon. There are two major types of hydrocarbons;

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

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

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

The chemical equation for the process is: Cl2(g) + 2OH- (aq) ---> ClO- (aq) + Cl- (aq) + H2O (l) The amount of hypochlorite ion present in a solution of bleach can be determined by oxidation-reduction titration. One of the best methods is the iodine-thiosulfate titration procedure. Iodide ion‚ I-‚ is easily oxidized by almost any oxidizing agent (It has many electrons to lose!). In an acid solution‚ hypochlorite ions oxidize iodide

When rounding calculated numbers‚ we pay attention to significant figures so we do not overstate the accuracy of our answers. Rules: -All nonzero digits are significant. -Zeroes between two significant figures are themselves significant. -Zeroes at the beginning of a number are never significant. -Zeroes at the end of a number are significant if a decimal
