Discussion for Experiment 1 (Basic Laboratory Operations and Identification of a compound : Chemical Properties) In the first experiment‚ the precision of instrument was studied by measuring the mass of water for several times. The result shows that the mass measurement of the balance is precise since the masses of water in six trials are somewhat close. The reason that the masses of water in each trial are not identical may come from the high sensitivity of the balance that keep fluctuating due

This is followed by the list of objectives of the experiment‚ telling exactly what was expected from the laboratory and what information we wanted to gather from the experiment. The theory section explains the logic behind some of the formulas used and results gathered. The experiment as a whole is discussed with the experiment’s method explaining all the

No matter who are the workers‚ what is their race‚ religion‚ and so forth‚ they still manage to have a very good rapport and relationship in the circle of the organizations. Regardless of their languages or beliefs‚ they tend to complete one task magnificently. To make it short‚ this diversity lies in their cultural intelligence‚ or CQ. Therefore‚ for the 21st

TITLE Basic Technologies of Handling Chemicals and Laboratory Apparatus INTRODUCTION Density is defined as mass per unit volume. The commonly used unit to indicate the density of water is (g/cm3). Water never has an absolute density because its density varies with temperature. Water has its maximum density of 1 g/cm3 at 4oC. When the temperature changes from either greater or less than 4oC‚ the density will become less than 1g/cm3 only when it is pure water. Other factors that

Experiment 1: Errors‚ Uncertainties and Measurements Laboratory Report Abstract The success of an experiment greatly depends on how the group is able to execute it and how precise and accurate their results are. In this matter‚ errors and uncertainties in measurements are of great factor. In this experiment‚ the group was able to classify the causes of such errors and which measuring device is more precise and accurate than the other. These were obtained by measuring the diameter of an iron sphere

Full Blood Count is a test used to evaluate the composition and concentration of the cellular components of blood such as red blood cells‚ white blood cells‚ platelets‚ etc. The abnormality it could identify are anaemia which means that there are less red blood cells or less haemoglobin in red blood cells than normal; polycythaemia which means there are too many red blood cells due to various causes; leucopoenia which means there are too few white cells due to various causes; leucocytosis which

Laboratory 3. Empirical Formula Of An Oxide This experiment will demonstrate the law of conservation of mass‚ and more specifically‚ how the law can be used to experimentally determine the empirical formula of our intended product‚ magnesium oxide. In this experiment we will learn how to: 1. heat a sample in a crucible with a Bunsen burner. 2. use the method of weight by difference to determine mass quantities. 3. convert grams to moles. 4. determine the simplest ratio between two

Laboratory Report: Flame Colors of Metals Abstract The experiment about flame color of metals demonstrates how electrons jump into their excitedstate from their ground state as it came in contact with heat. As it return to its lower energy state‚it emits the absorbed energy in the form of light. A platinum or nichrome wire was dipped into aconcentrated HCL and was heated to clean it. The wire was dipped into different salt solutionsand heated in order to determine the metallic ion’s color and wavelength
