the relative differences in strength that results from ionic‚ covalent and metallic boding. There are two types of bond‚ the strong bonds and the weak bonds. Covalent bond is part of strong bond and it has the highest strength among the strong bond. Ionic bond is part of the strong bond but the strength of ionic bond is a medium strong bond. The metallic bond is also part of the strong bond but the strength of the metallic bond is the weakest among the strong bond. QUESTION

ionic) I) Reactions with hydrochloric acid and/or sodium hydroxide. It is expected that some trends will appear across the period three oxides. Conductivity of electricity of molten oxide is likely to occur in the metal oxides as they have giant metallic structures which are capable of transferring delocalized electrons throughout their structure. This is not true of giant covalent structures and covalent bonds where all of their electrons are concerned with bonding‚ and therefore conductivity will

Define the following terms: 1. Horizontal Cable : A type of inside cable designed for horizontal use in non-plenum areas. While horizontal cable must be fire retardant‚ the National Electrical Code (NEC) specifications are not as demanding as those governing the use of plenum cable or riser cable. See also NEC‚ plenum‚ plenum cable‚ and riser cable. 2. Backbone Cable : Backbone cabling is the inter-building and intra-building cable connections in structured cabling between entrance facilities

laboratory analysis of metallic equipment for timely prediction of mercury deposition. Pure mercury during flushing or Mercuric sulfide deposition from environment is possible on metallic surfaces‚ however the mechanisms by which mercury is absorbed by steel are not known conclusively but reaction with grain boundary elements or compounds is the most likely postulate. Simple cleaning and decontamination treatments often suffice for completely retrieve mercury on metallic equipment Removal of mercury
