Chemistry Summary The particle theory: 1. Matter is made of tiny particles 2. Particles of matter are in constant motion 3. Particles of matter are held together by very strong electric forces 4. There are empty spaces between the particles of matter that are very large compared to the particles themselves. 5. Each substance has unique particles that are different from the particles of other substances 6. Temperature affects the speed of the particles. The

Fermentation of Carbohydrates: Ethanol from Sucrose Objective: To demonstrate a fermentation process‚ isolate the ethanol produced by fractional distillation‚ determine the composition of the ethanol solution recovered‚ and make stoichiometric and yield calculations. Procedures: Fermentation Weigh out 20.0 g of sucrose and place it into a 250-mL Erlenmeyer flask. Add 100 mL of water and gently shake until all the sucrose has dissolved. To this solution add 0.60 g of dipotassium hydrogen phosphate

Abstract In vitro studies show that tea tree oil can be used as a topical methicillin-resistant Staphylococcus aureus (MRSA) eradication regimen in a laboratory setting. This report has been researched using a wide range of journals and internet sources to find out whether tea tree oil can be used as an alternative to Mupirocin for those suffering from MRSA colonisation. The journals that were searched contained useful information about tea tree oil as an antiseptic‚ however‚ many of the studies

Distillation is a commonly used method for purifying liquids and separating mixtures of liquids into their individual components. Familiar examples include the distillation of crude fermentation broths into alcoholic spirits such as gin and vodka‚ and the fractionation of crude oil into useful products such as gasoline and heating oil. In the organic lab‚ distillation is used for purifying solvents and liquid reaction products. To understand distillation‚ first consider what happens upon heating

17‚ 2012 Abstract The distillation process was successfully done because of the separation of water from the acetone. When the distillate was lighted with the matchstick it produced flame which indicates that there was more presence of acetone than water. When the sodium nitroprusside‚ sodium hydroxide and glacial acetic acid was added to the distillate‚ it turned to violet. This means that there is the presence of ketone. Introduction Distillation is the process heating a liquid
