Procedure: Melting point of RCO2H Before observing the melting point of the unknown sample‚ the melting apparatus had to be standardized with a standard substance having the melting point of 151°C-153°C. After placing a small sample of the standard in a capillary tube and inserting the tube into the sample tube holder‚ the plateau on the device was set to 15°C below the expected melting point. After its temperature reached the plateau‚ the temperature increment was set at 1°C per minute‚ and the

Determination of blood type Introduction: A blood type is a classification of blood based on the present or absence of inherited antigens substances on the surface of RBCs‚ these antigens are made by proteins‚ carbohydrates‚ and glycolipid‚ Now there are total of 8 blood type known for the international society of blood transfers ( ISBT)‚ Also 600 antigens are known for ISBT‚ Antigens are a type of protein (Y shaped) found in blood and it has a great role in the immune system to recognize any

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

Complexometric Determination of Water Hardness Mike Monaghan CHM 152LL 01/27/2013 Abstract: What can be found from this experiment is as follows‚ Introduction/Background: This lab was about determining water hardness. Water hardness is the amount of metal ions in the water. The most common found ion in the water is calcium ions and typically with a charge of +2. Water hardness plays a big significance in our daily life because to many metal ions in our drinking water can have adverse

Germ Line Control of female Sex Determination in Zebrafish In order to identify the sex of a developing embryo‚ many scientists have studied this process called sex determination that allows them to have better understandings on how sex is being determined in either vertebrates or invertebrates. Sex determination is normally determined genetically; however‚ other factors can contribute to its determination. There are numerous determinants that control sex determination‚ but the most important are sex

at hand‚ and the determination that whether we win or lose‚ we have applied the best of ourselves to the task at hand.” Determination can be a characteristic used to describe someone based on their actions. Unlike other words that describe a person determination has a positive connotation attached to it. Every individual has a unique combination of characteristics that make up who that person is and what their work ethic or style is. The most common definition for determination is the unwillingness
