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

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

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

Lab Title: "The Effect of Salt on the Boiling Point of Water" Lab Question: How does adding salt to water affects it’s boiling point? Prediction : In this paper‚ a newly proposed model based on solvation between pure solvent and salt for prediction of salt effect on vapor–liquid equilibria is presented by using only the vapor pressure depression data of pure solvent+salt systems that compose the mixed solvent with salt system Materials : 200 mL of distilled water‚ 2 beakers

I expected‚ I found that it boiling point was 60C but in my experiment it was 30 C it’s the double of what it should be. Most of the sample like methanol and ethanol was pretty clos to the result that I found on internet. The trial that I did was Butanol again with the hot plates and it took of course much longer to boil and it started to boil before 105 °C like at 103 °C and I didn’t expect that happen maybe because of the boiling water it accelerated the boiling point. I don’t consider

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

Hypothesis: I think that in this experiment the results of the boiling point of each sample is going be slighly different from what I found on Internet. aim: my aim is to look at what temperature and how long the following alcohol (methanol‚ I-butanol‚ Ethanol and Hexane) reach their boiling point and comparing the results that I found on internet and mine. Materials: Alcohol: Ethanol‚ I-Butanol‚ Ethanol and Hexane Four Test tubes (boiling tube) Test tubes holder Data logger Hot plates Bunsen burner

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
