In the US‚ the largest desalination plant is located in Florida‚ but other states such as Texas and California are also beginning to develop desalination

TESTING YOUR COMPREHENSION 1) Why are fossil fuels our most prevalent source of energy today? Why are they considered nonrenewable sources of energy? Today‚ the three main fossil fuels that are in demand are oil‚ coal and natural gas. These fossil fuels are prevalent because they are efficient to burn‚ ship‚ and store based on high energy content. Fossil fuels also provide for our daily needs such as transportation‚ heating‚ cooking and electricity. Based on our current rates of consumption‚ we

7.4 Case Study: The Haber Process: Ammonia for Food and Bombs From: Eros Wang To: Ms. Irumekhai Date: March 30‚ 2012 1. Suggest five factors that could affect the production of ammonia in the Haber process. Explain the effect of each factor‚ using rate theory. The Haber process itself is a delicate balancing act because of all the factors that affect the yield of ammonia. In the Haber process‚ the nitrogen‚ hydrogen and ammonia are in equilibrium. So five factors that affect the

(water) =1000 kg/m3 . Volumetric gas flow rate V (m3/s) is calculated by assuming a flat velocity profile inside the tube. This is justifiable as the flow is turbulent V= v * s’ Where s’= pipe cross sectional area Vapor velocity inside the distillation column (v) = PROCEDURE: • Allow water to pass through the equipment to ensure the plates are loaded with liquid and then stop the water flow. Wait till the excess water is drained from the plates. • Set the inclined manometer to a suitable

the first step‚ the mixture of water‚ concentrated sulphuric acid‚ and cyclohexene was shaken vigorously until it became a homogenous solution. Followed by‚ the addition of water‚ and the distillation process lead to the hydrolysis of the alkene. Finally‚ addition of diethyl ether to the mixture then distillation took place to be purified and to obtain the final product‚ cyclohexanol (McFadden‚ 2012). Diethyl ether was used to extract alcohol from salt-water mixture because diethyl ethers solubility

In this experiment‚ we used simple distillation and extraction to do synthesis of 1-bromobutane. The experiment was carried out by mixing 13.3 g of sodium bromide‚ 15 mL of water and 10 mL of n-butyl alcohol in a 100 mL round bottom flask. We cooled the mixture and added 11.5 mL of concentrated sulfuric acid. Then the mixture was heated at reflux with a short condenser for 45 minutes and then we drained out the condenser. We removed the condenser and distillation head was set up to set up the condenser

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
