Purpose The purpose of this lab is to find the boiling point of the liquid and find the melting point of the solid. Procedure Boiling point: To find the boiling point of Isopropyl Alcohol I put about 1 mL of it in the test tube. Then I attached the thermometer to the test tube with a rubber band(make sure the thermometer bulb is lined up with the end of the test tube). After that I made a water bath with a beaker and put in the test tube with the thermometer. I then used a burner and a burner stand

Unlike most fairy tales‚ "Beauty and the Beast" has been a traditional tale where there are two paths to be developed in which Beauty faces challenges and the transformation that is sustained by Beast. Therefore‚ this shows how two opposing allegorical characters resolve their differences in joining wedlock. The version of "Beauty of the Beast" by Madame de Beaumont shows how Beauty ’s happiness is found on her abstract quality of good features. In this version‚ Madame de Beaumont not only stresses

classes average set of results by about 2‚ but‚ when graphing the alkalise by the boiling and melting point they both follow the same slope‚ it continues to rise just like the results gathered in the example do. 2. Which of the 2 unknown substances was which? How did you figure this out? The two unknown substances were the methanol and propenol because each of them were being tested in this experiment to discover the boiling point of each of these alcohols by analysing each of their temperatures to eventually

Once upon a time there was a frog who croaked away in Bingle Bog. Every night from dusk to dawn‚ he croaked on and on. Other little animals around loathed his voice but they were left with no choice. The crass cacophony; a very loud and unpleasant noise blared out from the sumac tree. At whose foot the frog sang till the break of dawn. The stones‚ prayers‚ sticks‚ insults‚ complaints and bricks could not silence the frog’s determination to display his heart’s great pride and joy. One

plethora of trees which cover the tropical floor of the Andes mountains. There is one animal‚ the glass frog‚ that is native to this country and has a unique physical characteristic. Glass frogs have made their home in the forests of Ecuador and Peru and feature a translucent underside which makes their internal organs visible. They live remarkable two-phase lives‚ hopping from tadpole to frog. But there is an issue that has developed in the region of Ecuador relating to these unique creatures

Background: As members of the class Amphibia‚ frogs may live some of their adult lives on land‚ but they must return to water to reproduce. Eggs are laid and fertilized in water. On the outside of the frog’s head are two external nares‚ or nostrils; two tympani‚ or eardrums; and two eyes‚ each of which has three lids. The third lid‚ called the nictitating membrane‚ is transparent. Inside the mouth are two internal nares‚ or openings into the nostrils; two vomerine teeth in the middle of the roof

Pithing and Muscle Preparation. The method for pithing the frog and preparing the frog gastrocnemius muscle will be described by the instructor. The object of the pithing operation is to destroy specified parts of the central nervous system. In this case the frog is pithed as a means of immobilization and anaesthesia. Generally‚ pithing the spinal cord only is adequate. To skin the frog leg‚ cut the skin all around the upper end of the leg. Pull the skin down the leg‚ freeing it from
