acid and majority of methanol). Again wash the ether with 25ml of water and then wash the organic layer with 25ml of 10% sodium bicarbonate to extract unreacted benzoic acid. Again shake separatory funnel with frequent venting of pressure and opening the stopcock. Allow the separation of layers and drain off bicarbonate layer into a beaker. Wash ether layer with saturated sodium chloride solution and retain ether layer. In a small 125ml Erlenmeyer flask, dry the ether solution over anhydrous calcium

Amino acids are known as the building blocks of all proteins that consists of 20 amino acids which are found in within proteins convey a vast array of chemical versatility. Amino acids are comprised of a carboxyl group and an amino group that attached to the same carbon atom which is the α carbon. They vary in size, structure, electric charge and solubility in water because of the variation in their side chains (R groups). Detection, quantification and identification of amino acids in any sample

Dangerous hair products In recent years, many people are choosing natural products for hair and skin care. The main reason for that is the fact these products are full of chemicals and harmful toxins that may have a negative impact on the health. Many researches and studies have shown that nutrition is very important, but it is not the only way how the toxins and chemicals can get into the bodies. Another option that is often completely disregarded, is by regularly using and applying certain products

In both ‘Digging’ and ‘Follower’, Heaney creates a tone of respect and admiration for his father and grandfather that permeate all aspects of the poems. He portrays them as being strong, skilful and dedicated; this is achieved through the use of vivid descriptions, structure and careful placement of words with connotations. In ‘Follower’, Heaney portrays his father as skilled and knowledgeable. Throughout out the poem, Heaney uses specialized terms to describe his father’s job, such as ‘shafts’

The saponification (a reaction in making soap) process is a base (usually NaOH or KOH) hydrolysis of triglycerides to make salt (soap) and glycerol. Alkalis such as Sodium carbonate and Sodium hydroxide are used to neutralize the fatty acid and convert it to a salt. The molecules crystallize differently depending on the base used. NaOH produces a harder bar while KOH is used more frequently for liquid soaps. In some cases, Lithium soaps are formed and produce much harder soaps. There are four

nitrate, sodium carbonate, calcium sulfate, and sodium phosphate. In Station 1, barium chloride and potassium nitrate did not react. Barium chloride and silver nitrate created aqueous barium nitrate and the precipitate silver chloride. In Station 2, potassium nitrate and silver nitrate did not react. Potassium nitrate and calcium sulfate did not react as well. In Station 3, sodium carbonate and calcium sulfate created aqueous sodium sulfate and the precipitate calcium carbonate. Sodium carbonate

obtained and chilled in an ice bath for three minutes. The ether was then added to the centrifuge using a pipette. In step four, it was observed that using a wooden stick helped dissolve the simple quicker. Once fully dissolved, one milliliter of 0.5 M sodium hydroxide was added in step four and it was observed that there were two layers. With water being denser, it was observed at the bottom later. In step five, the top layer was rinsed with the bottom layer ten times. In step seven, the aqueous phase

actual yield is 0.38 grams. So if 0.38 is divided by 0.49 and multiplied by 100 then the percent yield for Zinc Sulfide would be 77.6%. When it comes to Sodium Chloride, the theoretical yield is 0.58 grams and the actual yield is 0.45 grams. So when 0.45 grams is divided by 0.58 grams and multiplied by 100, the percent yield would be 77.5% of Sodium chloride. The actual yield is directly taken from the mass of the products in the experiment while the theoretical yield is determined by using stoichiometric

reaction would be higher. Those factors would affect the speed and the amount the atoms are moving at therefore effecting the amount that the particles collide and hence impacting the rate of reaction. The two reactants involved in the experiment are Sodium Thiosulfate

percent yield we reached was 130% yield which is clearly much more than the perfect 100% yield. Oddly, the yield was greater than 100%, meaning that we ended with more copper(II) oxide than should have been possible considering how much copper(II) sulfate we started the reaction with. We indeed did have an experimental yield of 0.850 g which is almost two hundredths of a gram larger than the theoretical yield of 0.6531 g. This would be considered rather unsuccessful as a result of the almost impossible

First, excess Ba^2+ was tested by adding 3 drops of 0.1 M sodium sulfate to test well 1A and is observed. Following this test, record the data in you’re stage 1 data sheet. Once excess Ba^2 was tested, Excess IO3 is tested by adding 5 drops of sodium bisulfate indictor solution to well 1B to be observed. The observations were recorded in the stage 1 data chart. The excess tests were repeated using pipet

Introduction The majority of ionic solids are soluble in water, the ones that are not, form precipitants when two aqueous solutions are mixed. When certain cations and anions combine, they create a solid product called a precipitant, but determining factors of the formation may vary. These can form because of chemical reactions (demonstrated in this experiment) or by the change in the solubility of a substance by the change in temperature, pressure, etc. Precipitants are most likely to form in an

The Citric Acid Cycle/ Kerbs Cycle/ TCA The Citric acid cycle is important as anaerobic glycolysis can only harvest a fraction of the energy from glucose. In the citric acid cycle there is aerobic respiration of pyruvate from step ten in glycolysis to C02 and H2O. This oxidation of pyruvate can greater a higher yield of ATP. The citric acid cycle occurs in the mitochondria where ten ATP is produced. The main purpose of the citric acid cycle is to harvest electrons from the citric acid cycle and

salt makes contact with water, it seems to disappear. Although it may seem like magic, the salt is just dissolving. This is due to the bonds between the molecules being broken down. The most well known type of salt, NaCl, is just a combination of sodium and chlorine ions, which have a relatively weak bond strength. Conversely, the hydrogen and oxygen in water are bound together by covalent bonds. The positively charged end of the water molecule is attracted to the negative salt ion as well as the

The goal of the experiment is to synthesize a bromohexane compound from 1-hexene and HBr(aq) under reflux conditions and use the silver nitrate and sodium iodide tests to determine if the product is a primary or secondary hydrocarbon. The heterogeneous reaction mixture contains 1-hexene, 48% HBr(aq), and tetrabutylammonium bromide and was heated to under reflux conditions. Heating under reflux means that the reaction mixture is heated at its boiling point so that the reaction can proceed at a faster

Sodium carbonate (molecular formula: Na2CO3), is the water soluble sodium salt of carbonate. The pure product appears as a while, odorless powder with a strong alkaline taste. It has high hygroscopicity. It can be easily dissolved in water to form an aqueous solution with moderate alkalinity Sodium bicarbonate (IUPAC name: sodium hydrogen carbonate) is chemical compound with the formula NaHCO3. It is a salt composed of sodium ions and bicarbonate ions. Sodium bicarbonate is a white solid that is

Neonatal period is a period that refers the first 4 weeks or 28 days of life. It can be further divided into too early neonates (birth to 24 hours), early neonate (birth to 7 days) and late neonatal period (7 days to 28 days). The neonatal sickness pattern include: prematurity (32.30%), sepsis (28.91%), birth asphyxia (11%), meconium aspiration syndrome (5%), congenital malformations (5%), transient tachypnea of newborn (5%), neonatal jaundice (5%), intrauterine growth restriction (3%), infant of

experiment, racemic 2-methylcyclohexanone was reduced using sodium borohydride as a nucleophile to give a diastereomeric mixture of cis and trans secondary alcohols. The products were analyzed for purity using IR spectroscopy and gas chromatography. 1.2 g of 2-methylcyclohexanone and 10 mL of methanol were combined in a flask and cooled in an ice bath. Two 100 mg portions of sodium borohydride were added to the flask and stirred. 5 mL of 3M sodium hydroxide, 5 mL of de-ionized water, and 15 mL of hexane

“2.2 million people in the United States depend on a wheelchair for day-to-day tasks and mobility. 6.5 million people use a cane, a walker, or crutches to assist with their mobility”. Every single day, people varying in ages, struggle to live their lives due to conditions out of their control. Whether it be life threatening or not, it can have effects that are both socially and emotionally harming. Although some of them may change appearances on the outside, other people cannot forget that all people
