Beer’s Law Lab Report Abstract: The Beer’s law lab was conducted to determine the optimal wavelength of Co(NO3)2·6H2O with the use of spectrometry. The results determined that the optimal wavelength to study the absorbance of this salt was 500nm. It also demonstrated how transmittance of light and absorbance of light are inversely proportional because absorbance is calculated by multiplying transmittance by a negative log. Introduction: When one is studying chemicals‚ there are many important

Tittle : Absorption Spectra and the Beer-Lambert Law. ɛ Purpose : Understanding of Beer –Lambert Law Introduction : When light passes through the colour solution ‚ the molecules of the solution absorb the quantity of light at a particular wavelength . The amount of light which is absorbed by solution depend on two things. 1. The length of the pathway of light 2.Concentration of colour solution. These are all explained by the Beer-Lambert Law

EXPERIMENT I Photoreduction of Benzophenone Introduction The study of chemical reactions‚ isomerizations and physical behavior that may occur under the influence of visible and/or ultraviolet light is called Photochemistry. The fundamental principles for understanding photochemical transformations are that light must be absorbed by a compound in order for a photochemical reaction to take place‚ and that for each photon of light absorbed by a chemical system only one molecule is activated for

Murder mysteries streaming through the nation’s television channels have become a source of entertainment for some individuals; however‚ the officers that discovered the body of a local business man near Robins‚ NC were faced with the reality. The man’s cause of death was listed as drowning because he had a large amount of water located in his lungs. The water in the man’s lungs had a high concentration of phosphates. By analyzing water samples from Woodlake‚ Seven Lakes‚ Reservoir Park‚ and Lake

It is these kind of passages that riddle the novel. It is these passages that make it unique. Marie being blind might makes us think that her world is devoid of senses and colors‚ but it is just the opposite. Doerr spends an astonishing amount of time in the novel vividly describing Marie’s world and senses. He spends whole a chapter describing‚ through Marie‚ what a cave of snails feels like or what the crashing of waves sounds like. Even without her sight Marie’s world is full of senses. This also

Each element emits a unique color light. The purpose of this experiment was to observe these unique colors and calculate their energy. In order to observe this‚ we placed the physical elements in a 24 well plate‚ dipped wet q-tips into the wells to gather the element‚ and put it over the bunsen burner to observe the flame emitted. While observing the different flames‚ we saw that different elements did indeed emit unique flame colors. Colors such as red‚ violet‚ and turquoise were emitted. All of

The "XxXX" formula You have probably noticed a recurrent formula in binocular jargon‚ a formula such as 8x35 or 10x60. This refers to the concrete optical capabilities of the instrument. The number before the "x" represents the magnification power‚ while the number after the letter represents the aperture (or diameter) of the objective lens in millimeters. So a 8x35 binocular‚ for example‚ features a 35 mm lens and can make objects appear eight times closer to you. A 10x50 lens brings things 10

Ultra Thin Cloak Can Match Any Background! In the Movie Predator there was an Alien that would uses a Cloaking Device that would hide the Alien in Plain Sight‚ But the effect is far from Perfect‚ due to its attempt to conceal itself is Thwarted from the distortion of Light bending around it. Now‚ Researchers built an Ultrathin “Invisibility Cloak” that Gets around the Problem of Light Bending by turning objects into Flat‚ Perfect mirrors. Invisibility Cloaks are Designed to bend light around an
