Abstract Carbohydrates are important in metabolic processes for everyday physical and chemical actions. The carbohydrate‚ glucose‚ is a key component in generating adenosine triphosphate‚ also known as ATP. In order to analyze unknown glucose levels‚ a DNS assay was performed. By using 2-hydroxy-3‚5-dinitrobenzoic acid to oxidize the aldehyde group on the carbohydrate‚ the reducing end of glucose increases in absorbance of 540 nm. Using a UV spectrophotometer‚ the concentration was calculated

Inside the pages of Into Thin Air‚ Jon Krakauer displays in a morose but nostalgic way how human relationships are strengthened and built during crisis. The Mount Everest Disaster of 1996 may be an immense part of the novel‚ but facts and experience translates into emotions and

Experiment 9- Thin Lenses Introduction Experiment 9 introduced us to the concept of thin lenses. We were asked to determine the focal lengths of two converging lenses and one diverging lens. The following equations were used to calculate the focal lengths: 1/p + 1/q = 1/f where p is equal to the distance of the object from the lens and q is equal to the image length from the lens‚ and f is the focal point and 1/converging F+ 1/diverging F = 1/combined. The focal point is positive for converging

The book Into Thin Air is a documented disaster by climber Jon Krakauer. Published in 1997‚ Jon wrote about the devastating summit attempt by several different groups. This climb was stopped by a disastrous storm above the death zone killing eight people‚ including Rob Hall.

He was once again trying to keep his business booming by bringing more and more climbers

Abstract: One is to determine the gap energy of cadmium sulfide semiconductor thin film using the equation: Eg = h.c/ is the signal of the long wavelength limit of the absorption peaks (measured in the lab). The reaction between cadmium sulfide and NH3‚ in the presents of thiourea yield a of 579(nm). The % error of the reaction is 1.24%. Introduction: There are 3 types of metals for electricity conducting: metallic conductor‚ semiconductor‚ and superconductor. Metallic conductors
