Title: Liquids and Solids Purpose: The experiment will help determine two important physical properties‚ boiling and melting point‚ of liquids and solids. Procedure: Before starting the experiment I gathered all materials appropriate for the experiment and prepare a safe environment for my experiment. I record the boiling point of the Isopropyl Alcohol and the melting point of powdered Acetamide with lab equipment such as the thermometer‚ capillary tube‚ beaker‚ test tube‚ and burner fuel

Question 1 Consider the company’s operations during the years from 1975 to 1979‚ and answer the following questions: a. How has the above complex approach actually worked‚ over these four years? What was the outlook (as of the case date) for further progress in this matter? In 1975 Chaparral Steel commissioned minimill and started production. Minimills are different from traditional integrated steel plants. In minimill an Electric Arc Furnace (EAF) is used for steel making purpose and in downstream

Date of Experiment October 7‚ 2012 Report Submitted: October 7‚ 2012 Title: Liquids and Solids Purpose: The purpose of this experiment is to determine the boiling point of liquids and the melting point of solids. Procedure: I got all of my materials together and set up. I poured rubbing alcohol in a beaker and rubber banded it with the thermometer. I logged the last bubble that came out of the capillary tubes. After that I crushed the acetamide and carefully put it in the capillary tube

Decadent-looking and easy to hold‚ chocolate-covered strawberries make a good dessert or a snack for a sophisticated gathering. After working hard to wash‚ dry and decorate your berries‚ take the extra step of arranging them decoratively before serving them. Stacking them on top of one another will smear the chocolate and make them look less appealing. Platters of prettily arranged berries will please the eye and the taste buds.Read more: How to Arrange Chocolate Covered Strawberries | eHow.com http://www

finding the melting point of the unknown compound. The theory is that if a substance is pure‚ it will have a very specific melting point‚ within one or two degrees Celsius. This is in opposition to a mixed‚ or contaminated substance‚ which will have a broad melting range. Therefore‚ when we mix our unknown with samples of phenacetin and acetanilide‚ whichever mixture has a more accurate melting point will tell us what our unknown is. It is also important to make sure that the resulting melting points
