Empirical Formula of a Compound * Purpose: To determine the empirical formula of Magnesium Chloride. * Data 1. Mass of evaporating dish = 45.08g 2. Mass of evaporating dish and Magnesium = 45.17g 3. Mass of Magnesium: { 2 } – { 1 } = 0.09 4. Mass of evaporating dish and Magnesium Chloride First weighing = 45.48g (After heating and cooling) second weighing = 45.49g 5. Mass of Magnesium Chloride: { 4} – { 1 } = 0.41g

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

Clean Up Of Chemical Waste Chemical spills are major problems that haunt the environment. Strict government regulation are trying help this problem‚ but governmental leaders face many challenges. Disposal of harmful chemicals is often difficult and costly. Since chemical waste has destroyed the environment‚ steps are being taken to prevent further pollution‚ Like the Yucca mountain project. A local based pharmaceutical company named Novo Nordisk released its 1999 environmental report. The company

Experiment #1: Introduction to Experimentation Submitted by: Neann Klara M. De Jesus BS Psychology II Submitted to: Dr. Geraldine E. Tria ABSTRACT SUMMARY The first experiment done by the class was called “Introduction to Experimentation”. Its main objective is to give basic knowledge about some of the logic of experimentation. The class was divided into groups of 2. In each group there was an experimenter (E) and a subject (S). The experimenter instructed

Hazardous chemical waste in the Liverpool area The aim of my research action plan is to address how people disposed of their hazardous chemical waste from households and schools within the Liverpool area. What is hazardous chemical waste? Chemical waste is a waste that is made from harmful chemicals such as: * Paint/ artist paint/ paint thinner * Motor oil * BBQ gas cylinders * Insect sprays * Rat poisons * Garden chemicals- fertilisers ‚ insecticides * Car wax

To perform the experiment‚ first the calorimeter was filled with 100 mL of water using a graduated cylinder‚ and the temperature of the water was found and recorded. Next‚ the beaker was filled 3/4 full with water and placed on the stand of the ringstand above a gently burning flame from the Bunsen Burner. Then‚ the mass of the test tube and wax was found

Experiment #6: Colorimetric Determination of pH Almira‚ Faerie Carleen Lucile L. Gallardo‚ Charlotte O. Group #6‚ Chemistry 18.1‚ MHEG1‚ Ma’am Arlou Angeles September 23‚ 2013 I. Abstract The acidity of the four unknown solutions were determined with the use of colorimetry using McIlvaine’s buffer solutions varying in proportion of its constituents (disodium phosphate and citric acid). These buffer solutions were subjected to the addition of corresponding pH indicators and the variation of
