Lab report on separation of mixtures Purpose- The purpose of this lab is to separate or isolate the desired product from large amounts of solvent and by-products. It is also followed by a purification step that removes trace amounts of other substances from the final product. One of the experimental techniques that we used in the lab to separate or purify mixture is fractional crystallization. In the experiment we used fractional crystallization to resolve a mixture of salicylic acid and CUSO₄

Until‚ a boy gets a face painting that’s generally associated with a girl. Maybe there’s a reason for it like: an older sibling of the opposite sex had one or he’s forever fascinated with the subject and that’s his way of expressing it. On the other hand‚ it is okay for a little girl to have a masculine

gay men in contrast to those in the middle and low class who interact with men of both homosexual and heterosexual preferences. This‚ therefore‚ puts gay men of low social status at a greater risk for HIV/Aids than those who are less unfortunate. Alcohol in Brazil is also heavily promoted as a leisure context and is seen as a social norm for males to consume. (Carlos F. Ca´ceres‚ 2002) Gay

Alcohol consumption is the most major causative factor which contributes to liver cirrhosis (Farrell& Dempsey 2011‚ p.1166). Therefore‚ it is significant to the nurse to have a good knowledge of test result and prescription medication relating to alcoholic cirrhosis. This assignment will explore a case study of Mr Chocolate‚ who presented to the hospital with sign and symptom of alcoholic cirrhosis. It will contain a brief describe about how cirrhosis result in Mr Chocolate’s signs and symptoms

Understanding Gas-Condensate Reservoirs How does a company optimize development of a gas-condensate field‚ when depletion leaves valuable condensate fluids in a reservoir and condensate blockage can cause a loss of well productivity? Gas-condensate fields present this puzzle. The first step must be to understand the fluids and how they flow in the reservoir. Li Fan College Station‚ Texas‚ USA Billy W. Harris Wagner & Brown‚ Ltd.

Magnesium ion (Mg+) and two negative Hydroxide ions (OH-) Usage: Milk of Magnesia is used to combat constipation and difficulties resulting from too much stomach acid. Properties: Because it contains hydroxide‚ Milk of Magnesia is able to lower the acidity of the stomach by neutralizing some of the acid. It works as a laxative by drawing in water from the intestines. Common Name: Baking Soda Scientific Name: Sodium Bicarbonate Formula: NaHCO3 Fundamental particles: Baking

SYNTHESIS OF TRANS-9-(2-PHENYLETHENYL) ANTHRACENE (A WITTIG REACTION) Introduction: The purpose of this experiment is to convert carbonyl compounds to alkenes using Wittig reaction. In this case we will be synthesizing Trans-9-(2-phenylethenyl) anthracene from benzyltriphenylphosphonium chloride and 9-anthraldehyde. We will also aim to obtaining a high percent yield and purity for the synthesis of Trans-9-(2-phenylethenyl) anthracene. The mechanism for this reaction goes thus:

Pour the aloe vera extract‚ lemon juice and baby oil in pot and simmer using lower heat temperature until it boil. 4. After you simmer/boil the mixture‚ add the banana peel and continue to boil it. 5. Finally‚ if the solution became viscous‚ set it aside and make the insect repellant.

evidence that help conclude that the mystery mixture ( number 8) is composed of citric acid and sodium bicarbonate the same as mixture six . At first when just observing the dry mixtures‚ it was hard to determine which ones were identical to the mystery mixture. In order to figure out which substances combined to make the mystery mixture‚ another process we followed was adding water to the substances and observing the reaction. Adding water to the mixtures resulted in a chemical reaction. The materials

SEPERATION OF A MIXTURE Purpose: The purpose of this lab is to find out how components of a mixture can be separated and analyzed. Procedure: The procedure for this lab report is as follows: 1. Mixture is taken‚ and has to be measured in order to meet the requirements of 2-3g. 2. The mass of the tray is measured and then the scale is zeroed out and the mixture is added to find out the mass of the original mixture. 3. Next‚ find the mass of the 250mL beaker‚ zero out the scale
