The existence of He + 2 should be predicted. Concept Introduction: According to molecular orbital theory, covalent bonds result when atomic orbitals combine to form molecular orbitals. Minimum energy corresponds to maximum stability. Two atomic orbitals combine to give a bonding MO and a higher energy antibonding MO. Electrons in a bonding MO assist in bonding. Electrons in an antibonding MO detract from bonding. Cylindrically symmetrical bonds are called sigma ( σ ) bonds; side to side overlap of parallel p orbital forms a pi ( π ) bond. Bond strength is measured by the bond Dissociation energy .

Answer 1

Question

Formula Formula Bond dissociation energy (BDE) is the energy required to break a bond, making it an endothermic process. BDE is calculated for a particular bond and therefore consists of fragments such as radicals since it undergoes homolytic bond cleavage. For the homolysis of a X-Y molecule, the energy of bond dissociation is calculated as the difference in the total enthalpy of formation for the reactants and products. X-Y → X + Y BDE = Δ H f X + Δ H f Y – Δ H f X-Y where, ΔHf is the heat of formation.

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…
