hydrocarbons. Several reactions such as Bromination‚ oxidation‚ and the addition of sulfuric acid were done to understand the chemical properties as well as the possible products that may form by each of the classification of hydrocarbons. Preparation of acetylene was also done in this experiment. The properties of the formed acetylene such as the reaction of the acetylene as it undergo Ammoniacal silver nitrate test‚ Bromination and oxidation. The reagents that were used to perform this experiment

classify chemical reactions in various ways. Often a major classification is based on whether or not the reaction involves oxidation-reduction. A reaction may be classified asredox in which oxidation and reduction occur or nonredox in which there is no oxidation and reduction occurring. Redox Reactions A redox reaction can be recognized by observing whether or not the oxidation numbers of any of the elements change during the

Lanthanides and Actinides The lanthanides and the actinides make up the f block of the periodic table. The lanthanides are the elements produced as the 4f sub level is filled with electrons and the actinides are formed while filling the 5f sub level Some significant similarities and differences between lanthanides and actinides are observed. The two rows that are generally placed underneath the main periodic table are called the lanthanides series and the actinides series. These two rows are produced

An antioxidant is a molecule that inhibits the oxidation of other molecules. Oxidation is a chemical reaction involving the loss of electrons. Oxidation reactions can produce free radicals. These radicals can start chain reactions. When the chain reaction occurs in a cell‚ it can cause damage or death to the cell. Antioxidants terminate these chain reactions by removing free radical intermediates‚ and inhibit the oxidation reactions‚ hence prevent the damage caused by oxidation to cells. Therefore‚ if we have insufficient

In this review article‚ the potential mechanisms will be showed from five aspects: lowering cholesterol level‚ inhibiting oxidation of LDL‚ improving vascular endothelial function‚ decreasing blood pressure and having anti-atherosclerotic effect. In the discussion part‚ the adverse effects of high consumption of green tea will be showed. To sum up‚ there is no conclusive evidences

types of valencies namely‚ primary and secondary valencies. Primary valencies are satisfied by negative ions while secondary valencies are satisfied by both negative and neutral ions. (In modern terminology‚ the primary valency corresponds to the oxidation number of the metal ion‚ whereas the secondary valency refers to the coordination number of the metal ion. (ii) A metal ion has a definite number of secondary valencies around the central atom. Also‚ these valencies project in a specific direction

Some of the main processes of chemical weathering are: 1. solution‚ 2. hydration and hydrolysis‚ 3. oxidation and reduction‚ 4. carbonation‚ 5. base exchange‚ and 6. formation of colloids. 1.
