The Lewis structures of SeF 4 and SeF 6 are to be represented, Also, whether the molecules obey the octet rule or not is to be stated. Concept introduction: The Lewis structure is a representation of bonding and nonbonding electron pairs present in the outermost shells of the atoms present in a molecule. The number of bonds formed by an atom in the molecule is determined by the valence electrons pairs. Dots are placed above and below as well as to the left and right of symbol. Number of dots is important in Lewis dot symbol but not the order in which the dots are placed around the symbol. In writing symbol pairing is not done until absolutely necessary. For metals, the number of dots represents the number of electrons that are lost when the atom forms a cation. For second period non-metals, the number of unpaired dots is the number of bonds the atom can form. Atomic ions can also be represented by dot symbols, by simply adding (for anions) and subtracting (for cations) the appropriate number of dots from Lewis dot symbol. An atom becomes unreactive after its octet of eight electrons gets completely filled.

In addition to the separation techniques used in this lab (magnetism, evaporation, and filtering), there are other commonly used separation techniques. Some of these techniques are:Distillation – this process is used to separate components that have significantly different boiling points. The solution is heated and the lower boiling point substance is vaporized first. The vapor can be collected and condensed and the component recovered as a pure liquid. If the temperature of the mixture is then raised, the next higher boiling component will come off and be collected. Eventually only non-volatile components will be left in the original solution.Centrifugation – a centrifuge will separate mixtures based on their mass. The mixture is placed in a centrifuge tube which is then spun at a high speed. Heavier components will settle at the bottom of the tube while lighter components will be at the top. This is the technique used to separate red blood cells from blood plasma.Sieving – this is…
