In order to complete this lab in a proper manner, the concept of the beer-lambert law must be understood to ensure success in the experiment. the Beer Lambert Law compares the property of light with material through which the light is travelling.4 So, if all the light passes through a solution without any absorption, then absorbance is zero, and the percent transmitted is 100%. If all the light is absorbed, then percent transmittance is zero, and absorption is infinite.3-4 There are many forms…

For instance, the film shows the NSA utilizing the Kent Island Intercept Station as a beacon for orbital satellite relays to observe and track Zavits as a witness to the murder of Hammersley (“Enemy of the State” 17:47-17:55). In this instance, an official named Fielder (Jack Black) asks for “authorization” for the surveillance, and he is given an impromptu…

After viewing the video about female serial killers many of the female serial killers have striking similarities. Most of the female serial killers, at least presented in the video, were caregivers of those they killed. Many were mothers who killed their children and two were nurses who killed their own patients. Many of these mothers were motivated by the attention they received in the wake of their children’s deaths. The female serial killers also more commonly kill their victims using…

a “dwarf planet” in the solar system. Pluto is a planet with about 30 to 49 astronomical units away from the sun, and it takes about 5 hours for the light of sun to reach its surface. Pluto also has an orbit of 248 years, which makes the longest orbital time period for a planetary object in the solar system. The mass of Pluto is 1.303±0.003)×1022 kg and the radius of the planet is 0.1863 Earths. The small size of the planet makes it around one-sixth of the size of the moon, which made it the…

Electronegativity helps to explain polar molecules and the differences in ionic and covalent bonding.5, 6 Pauling went on to introduce two new concepts bond-orbital hybridisation and bond resonance both to help explain covalent bonding. Bond-orbital hybridisation, which occurs when atomic orbitals mix to form new atomic orbitals, also explained the arrangement of atoms in a molecule. Bond resonance describes the delocalisation of electrons seen in graphite. Pauling’s work during the 1920’s…

complex has a total charge of zero, ammonia has an oxidation number of 0, chlorine has an oxidation number of -1, cobalt has an oxidation number of +3. Therefore, there are four electrons in the d orbital of a cobalt in this complex. Figure 8 gives the possible high spin and low spin combinations for four d orbital electrons. The high spin config- uration has four unpaired electrons and the low spin configuration has two unpaired electrons. Figure 7. High and low spins for cobalt d electrons…

Electrical properties Figure. 8 shows the temperature dependence of resistivity of the Co(II), Ni(II) and Cu(II) complexes. As seen, the data reveal a semiconductor behavior where the resistivity decreases with the increases of temperature. The decrease of the electrical resistivity with increase of temperature is resulted from the increase of the charge carriers that can overcome the energy barrier and participate in the electrical conduction where in metal complexes, the metal…

described statistically Orbital- a probability distribution map showing where an electron is likely to be found Wave Function- a mathematical function that describes the wavelike nature of an electron Quantum Number- each orbital is specified by three interrelated quantum numbers Principal Quantum Number- n Angular Momentum Quantum Number- l Magnetic Quantum Number- ml Spin Quantum Number- ms Specifies the orientation of the spin of the electron Principal Level (Shell)- orbitals with the value…

The aim of this experiment is to reduce chromium (III) to chromium (II) using Zinc as an oxidising reagent using Schlenk techniques in the inert gas atmosphere using Nitrogen. The goal is not to let oxidation happen that will prevent the formation of chromium (II) species. Also, the aim of this experiment is to successfully form chromium (II) acetate, to find its percentage yield and to conduct IR analysis to prove the success of the reaction as well as the purity of the compound. Magnetic…

The Blepharoplasty Operation Surgery on the eyelids may be done as an isolated operation or in conjunction with a facelift, brow lift, or other procedure (see Chapters 11-13). Both upper and lower eyelids can be corrected at the same operative setting; alternately, one pair of eyelids can be corrected as an isolated procedure. The procedure is almost always performed around both eyes. Blepharoplasty is an outpatient procedure that is typically done with intravenous sedation and local anesthesia.…
