CHM1032L pre/post lab instructions Preparation is a key to success in this lab. For this reason‚ you are required to thoroughly read through the experiment information presented in the lab manual‚ and complete a pre-lab for each experiment you do. The prelab must be completed prior to the day of the experiment. Each Friday I will ask to see your completed prelab before I allow you to enter the lab. If you have not finished the pre-lab‚ I will not allow you to enter the lab and you will receive

An Autobiography of an Unknown Indian by Nirad C. Chaudhuri. In this book the author has depicted his “Early Environment” in book -1 which he talks about his “ My birth place”‚ “ My Ancestral village” where he has pass his old days‚ “ My Mother place” where he had lived for sometimes and also describe about “England” as he was very fascinated of it. So as the same he talks about his “parents and early 12 days” and something about “Nationalism” in book -2.In book -3 he talks about “Calcutta” how

Microorganisms are classified according to their structure. By means of flow charts‚ diagrams and tables explain the differences between Viruses‚ Bacteria‚ Cyanobacteria‚ Achaea and Fungi. Bacteria or bacterium are unicellular microorganisms. They are essentially only a few micrometres long and form of various shapes including the spheres‚ rods and spirals. A BACTERIAL CELL Illustration courtesy of Wikipedia. A Virus (from the Latin noun virus‚ meaning toxic or poison) is a sub-microscopic

Introduction: During this unknown lab report various test were performed to differentiate microbes from each other and to compare metabolic and biochemical process. The gram stain distinguishes between Gram positive and Gram negative bacteria based on the composition of the cell wall. The Gram stain procedure distinguishes between Gram positive and Gram negative groups by coloring these cells red or violet. Gram positive bacteria stain violet due to the presence of a thick layer of peptidoglycan

Acid Base Titration Purpose: The purpose is to calculate the molarity of a NaOH solution by titrating the base with 5mL of standard HCl solution in each trial. By adding the base with unknown molarity to the acid with 0.10M the molarity of NaOH can be calculated. The base‚ NaOH‚ helps bring the pH of the acid‚ HCl‚ closer to seven‚ which neutralizes it. When using the buret the amount of NaOH used is able to be determined. Then by writing a balanced chemical equation and using the titration

Hands of Persons Unknown Book Critique At the Hands of Persons Unknown‚ a novel by Philip Dray‚ is a decisive explanation to the past multiple acts of lynching in America. In the past‚ Caucasians were seen as superior to African Americans. Lynching was one of the many acts that gave whites this superiority. The gruesome act of lynching was overlooked by the nation as a whole. People didn’t think anything of it and some seen it as entertainment. At the Hands of Persons Unknown could be seen as a

Determination of an Unknown Concentration of Potassium Manganate using Colorimetry Introduction The purpose of this experiment is to conclude the concentration of an unknown solution using colorimetry to plot a calibration curve. Colorimetry measures the absorption of light at wavelengths within the visible region of the electromagnetic spectrum. It can be used to identify the unknown concentration of a solution in reference to a solution of a known concentration. When a solution appears

Lab Report Microbiology Introduction Bacteria can be found almost anywhere. For human life‚ some help us‚ some hurt us‚ and others are neutral. It is now known that good bacteria‚ or normal microflora‚ can reach 1014 microbial cells. This is far more than the 1013 cells that make up the human body (Tannock‚ 1995). The total number of bacteria on Earth is estimated to be around 4-6 x 1030 (Horner-Devine‚ 2004). It is important to know the extent of bacteria‚ how they live‚ and how they are

colorless colonies. Multiple medical experiments are credited towards transformation‚ especially ones involving cancer and the transformation of normal cells to neoplastic and cancerous cells. Introduction The general purpose of the Transformation Lab was to observe the difference in bacterial growth under differing media conditions to help understand the process of transformation and how it contributes to the life of living organisms. "Transformation" is what occurs when a cell receives and expresses
