this experiment are to be able to define equilibrium‚ equilibrium position‚ equilibrium constant‚ reaction quotient and Le Chatelier’s Principle. Another objective is to explain how changes in temperature‚ pressure and concentration affect the equilibrium position of a reaction. Also‚ perform chemical equilibrium reactions and manipulate equilibrium positions through concentration and temperature and perform calculations to determine the equilibrium constant (K) and the reaction quotient (Q) of reactions

Microbiology Lab Report II Title: Determination of a Bacteriophage Titer Purpose: To determine the number of phage particles or plaque-forming units in a suspension of T4 bacteriophage. Materials: 18 24 hour broth culture of Escherichia coli B. 2 ml suspension of T4 bacteriophages with a titer of at least 10‚000 phages/ml 5 trypticase soy agar (TSA) plates. These should be warmed to 37c before use 5 tubes of soft agar (0.7% agar). Prior

spread sample. 7. It is important because if the temperature is increased too rapidly at the melting point‚ the sample and the aluminum block will not be at the thermal equilibrium with the thermometer. 8. Rapidly heating the sample results in too high of a reading because the sample and aluminum bock are not at equilibrium with the mercury in the thermometer and this will result in a very high reading. 9. A mixed melting point analysis is preformed to determine the identity of an unknown sample

CHEM 1105 Experiment 4: Determination of a Chemical Formula Introduction When atoms of one element combine with those of another‚ the combining ratio is typically an integer or a simple fraction. The simplest formula of a compound expresses that atom ratio. When two or more elements are present in a compound‚ the formula still indicates the atom ratio. To find the formula of a compound we need to find the mass of each of the elements in a weighed sample of that compound. For example‚

Chemical Equilibrium: Le Châtelier’s Principle Abstract This experiment entitled "Chemical Equilibrium" aims to help students to investigate the effects of concentration and temperature upon the position of equilibrium in a cobalt chloride solution‚ Co(H2O)62+. In this experiment‚ cobalt crystal is dissolved with distilled water and ethanol which the initial colour is purple-pinkish and a few drops of concentration of HCl is added to the test tube‚ the final colour is in deep blue colour.

Determination. Determination is firmness of purpose; resoluteness also known as a quality that makes you continue trying to do or achieve something that is difficult. In so many stories you see so many people and characters being determined. But especially in the Panyee Football Club movie by TMB Brand‚ the boys learn that through hard work and determination you can achieve anything. Even though the villagers made fun of the boys the boys were determined. The boys ended up forming their own team

Gravimetric Determination of Calcium ABSTRACT Determining the mass of a pure compound is a method of a gravimetric analysis. One of the gravimetric analyses is the precipitation; it is a method of separating the analyte from the unknown sample as a precipitate where it will be filtered and converted into a known composition that can be weighed to determine its mass (Skoog et al‚ 2013). Determining the mass of calcium by using gravimetric analysis was the objective of the experiment. A 25 mL

HUM-101-010 Written Assignment 4 A Cultural Determination of Meaning Throughout historic culture‚ we can identify several changes in philosophical thought. Through the emergence of romanticism‚ we see a realization that‚ through passion‚ the paths of the hero and saint can be merged. In the agony and ecstasy of Michelangelo‚ it is obvious how the paths of hero and saint can be merged in the form of art‚ to attempt to reconcile the tension between them. In the enlightenment patterns of cultural

Abstract Rhesus typing is an important clinical technique which involves finding out whether some ones blood is RhD+ve or RhD-ve‚ it is important to find this out as it can have serious health complications if blood that is un compatible is mixed‚ either during pregnancy or transfusions. This experiment involved using the techniques of PCR to amplify the DNA collected‚ using electrophoresis to separate the DNA and using markers and positive controls of known size to determine the size of fragments
