certain cations and solutions is the main point of this lab. This has many real life applications. When creating buildings‚ or bridges it is important to understand and counter-act the rusting of iron. You can do that by using the activity series. For any industry using metals‚ this is important. Manufacturing cars‚ or producing construction supplies all ties in with the activity series. Without it‚ cars or buildings could very well be rusting and dissolving around us.

Translating the Diabetes Prevention Program to Primary Care: A Pilot Study Acknowledging that there is a need for the obese Type 2 diabetics (T2D) to make changes in their lifestyle‚ Whittemore et al. (2009) decided to do a study to see if there is a need for programs to decrease the incidence of Type 2 diabetes. The article selected is an example of experimental quantitative design. The summary model can be found in the text on pages 112 through 114 in Polit & Beck (2012). There were

LAB OF ENTHALPY CHANGE IN COMBUSTION Objective: Determine the Enthalpy change of combustion ΔHc of three different alcohols. Methanol‚ Ethanol and Isopropilic acid. Procedure: 1. Fill the spirit micro burner with Ethanol and weight it 2. Pour 100 cm3 of water into the aluminum cup 3. Arrange the cup a short distance over the micro burner 4. Measure the temperature of water 5. When the temperature of the water has risen by 10°C‚ record the temperature. 6. Reweight

Lactic acid bacteria(LAB)‚ a bacteria that can be found in the production of cheese‚ its stress gene was investigated in the experiment by using various biochemical and genetic techniques to identify and extract. The characterisation of the strain illustrates how identification of strains differ using different methods‚ such as gram stain and 16s rRNA screening. After the characterisation‚ the stress gene isolation assist the further understanding of the gene on LAB be giving different stress

Introduction Chemical kinetics is the study of reaction rates. A reaction rate is the speed of the change in either reactants or products over a period of time. General kinetic rate equation is: Where [A] and [B] are the concentration of the species in the reaction. The variable k is the rate constant‚ which is a function of time and catalyst presence. The variables m and n are the order of reaction for their respective species concentration. The higher the value of the reaction order the

In this lab we are going to be observing the decomposition of piglets over a month’s time. There are theory questions that have been given to us before and after the lab. We look back at our original theory to see where we went wrong‚ and then correct it. The lab was disgusting‚ surprising‚ and very interesting. The first questioned to be answered is which piglet decomposes faster‚ a piglet that is in its natural state‚ that is burnt‚ that is buried‚ and that is buried in a wooden box? With

occurs. Reagents can be added to solutions to see if there is a presence of other substances. For example‚ iodine added to a lead solution. Iodine would be the reagent and would cause a chemical reaction confirming the presence of lead. We use a qualitative chemical analysis to identify elements present in the solutions‚ in this case‚ adding a reagent. A quantitative chemical analysis is used to determine the percentage of a substance in the solutions. Solvation is the process of the attraction between
