Julie Smith 2/14/2017 Bio 220 Lab Report Learning How to Use the Compound Light Microscope Introduction: Microscope is an instrument used to grow pictures of little questions that are difficult to see with the unaided eye. The compound light magnifying instrument‚ which will be utilized as a part of this lab movement‚ is an instrument with two focal points and different handles to center the picture. In this lab‚ we will learn about the proper use and handling of the microscope. Objectives:

bone has been displaced from the point in where it should be. There are different types of fractures with the most common being hairline and compound. Hairline fractures are where there is a very fine line between the segments of the bone that appears when x- rayed. The bone segments will remain in alignment and the fracture may not go fully through. Compound fractures are also known as open fractures so if the skin has been pierced the outside air must be able to get to the fracture site without

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

Mr. Brown all your tests look ok. Your triglycerides are at 145‚ cholesterol 210‚ hdl 33‚ and ldl 160. Triglycerides are chemical compounds digested by the body to provide it with the energy for metabolism. Triglycerides are the most common form of fat in the body. They are the main ingredient in vegetable oils and animal fats. Cholesterol is a soft‚ waxy substance found in all of your body’s cells. Your body needs cholesterol in order to work properly. This is because your body uses it to hold

Preparation of an Ionic Compound from Aluminum Metal October 6‚ 2010 The purpose of this laboratory project was threefold‚ in that it presented three main objectives. The first objective was to prepare the ionic compound alum from aluminum powder. The alum was produced from the reduction-oxidation reaction of aluminum with potassium hydroxide and sulfuric acid in water. The second objective was to then analyze the alum product for water crystallization; that is‚ to determine the value of x in

Writing ionic equations for redox reactions You can split the ionic equation into two parts‚ and look at it from the point of view of the magnesium and of the copper(II) ions separately. This shows clearly that the magnesium has lost two electrons‚ and the copper(II) ions have gained them. These two equations are described as "electron-half-equations" or "half-equations" or "ionic-half-equations" or "half-reactions" - lots of variations all meaning exactly the same thing!
