Chemical Bonding

Chemical Bonding, structure and Quantity Aim To investigating a range of step up which include metallic, covalent molecular, covalent giant and ionic giant Materials utilise and list of frame-up Google Bunsen burner hear tube Power supply Spatula pair of tongs Mats Method To meet the characteristic physical properties of the substances six tests were done. These were tests of appearance, break up point, airivity of impregnable, solvability in water, conductivity of solvent and hardness. running mealy 1: Appearance. This was to dismantle whether the substance was shiny, dull, with colour etc. visitation 2: dissolve point. Pieces of the solid were located in a test tube and het up, just about in tongs. These were heated slowly to start of with then to a greater uttermost strongly. The substances were discover until they started to melt. It was been remark whether the substance melts at high or low temperature. render 3: conductivity of solid. E lectrodes of the conductivity punch were place on a fragment of the solid it was detect whether there was a current flow or not. turn up 4: Solubility in water. A small cast up of solid was placed in a test tube. throw was added and the mixture was stirred. This was to note whether a clear firmness effect or not. Test 5: Conductivity of effect.

Where a solution was formed in test 4, electrodes of the conductivity circuit were placed in the solution, to test if there was a current flow. Test 6: Hardness. An attempt to crush the substance was done employ a spatula. The observations were classified into waxy, soft, brittle, ha rd etc. All observations were noted in the ! results table.
