Identify the differences between bacteria viruses‚ Fungi and Parasites. Viruses are pieces of nucleic acid (DNA or RNA) wrapped in a thin coat of protein that replicate only within the cells of living hosts. Bacteria are one-cell microorganisms with a simple cellular organization whose nucleus lacks a membrane. Parasites may be protozoa‚ yeasts‚ or multicellular organisms such as fungi or worms that live in or on a host to obtain nourishment without providing any benefit to the host. Fungi

Determination of An Unknown Amino Acid From Titration Abstract Experiment 11 used a titration curve to determine the identity of an unknown amino acid. The initial pH of the solution was 1.96‚ and the pKa’s found experimentally were 2.0‚ 4.0‚ and 9.85. The accepted pKa values were found to be 2.10‚ 4.07‚ and 9.47. The molecular weight was calculated to be 176.3 while the accepted value was found to be 183.5. The identity of the unknown amino acid was established to be glutamic acid‚

Quantitative Analysis Finding the Percentage Composition of Nickel in an Unknown Compound Introduction: This section of lab was about using analytical chemistry and learning how to identify the amount of nickel in an unknown substance. The purpose was to use gravimetric analysis to quantitatively separate and weigh insoluble reaction products as well as utilize the mole method to compute the amount and percentage of nickel in an unknown nickel sample. The chemical reaction that took place involved the

Ever since I was a little girl I dreamed about traveling overseas. Strange lands‚ exciting places‚ and new cultures have always fascinated me. I’ve always wondered what it would be like to speak another language‚ to grow up learning different customs‚ or to live in a completely different way than I do now. This past summer my dream finally came true. I got to travel to England‚ France‚ Switzerland‚ and Germany with Mme. Kelly and five other girls‚ and suddenly the world was at my fingertips. <br> <br>England’s

Experiment 5- Standardization of NaOH and determination of Molarity of an unknown Acid Objectives 1. Preparation and standardization of a 0.1M NaOH solution 2. To learn the technique of titration 3. Determination of the concentration of an unknown diprotic acid. Introduction Titration can be traced to the origins of volumetric analysis‚ which began in the late eighteenth century. Study of analytical chemistry began in France and the first burette was made by Francois Antoine Henri

Carlie Haeffner Qualitative Analysis March 20‚ 2015 The purpose of this lab is to identify unknown ions in a solution by using a type of chemical reaction called precipitate reactions. The key to finding which ions are present in a solution is to form a precipitate which makes the ions “come out” in a reaction (McNeil‚ 2013-2014). Water is used in these experiments to act as a solvent. Since water is a polar molecule‚ the slightly positive and negative charges will sometimes pull apart molecules

Determining the Unknown Concentration of NaHCO3 (aq) Through Titration Introduction Titration is the accurate addition of a titrant- solution in a burette- into a measured volume of a sample (Kessel‚ 2003). There are many different types of titration‚ such as acid-base reaction‚ redox reactions‚ precipitation reaction and more (Dohrman). In this lab an acid base titration will be explored. In an acid-base titration‚ the concentration of an acid or base is unknown and is determined by the adding

The 13C NMR spectrum was useful to help finding the structure of the unknown. It showed six different signals in the spectrum. Signal 1 had an observed peak value of 19.242 ppm‚ and its peak calculated value was 19.1 ppm. This signal was first to most upfield and shielded in the spectrum because of the high electron density of carbon. This signal was agreed to a literature value for a CH3 group between 5-30 ppm. Signal 2 was branched to signal 1‚ and had the same value‚ but it was agreed for the
