Experiment 2: Preparation and Spectrophotometric Analysis of Copper(I) Iodide Abstract: This experiment aims to determine the concentration of “Purified CuI” sample. Crude CuI is obtained by reacting CuSO4.5H2O with KI and Na2S2O3 in de-ionized water. A series of decanting and centrifugation is carried out to extract the crude CuI. Crude CuI was later purified by dissolving it in hot KI solution. The solution was later transferred into de-ionized water and placed in an ice bath to allow for re-precipitation

Hatchet, by Gary Paulsen, has 195 pages and 19 chapters. A thirteen year old boy named Brian Robeson was on a plane to see his father in Canada. The only other person on the plane was the pilot. Since he was the only other person on the plane, the pilot showed him how to use the controls. The pilot suddenly started to have a heart attack in the middle of the flight and soon died. Since the pilot taught him, Brian flew the plane. He also tried to call for help, until the plane ran out of fuel and

Jacob Lawrence was a 20th century African American painter who considered his work to be “dynamic cubism.” He designed this Gouache on paper not so much for his love of French art but rather because of his love for bold colors seen in Harlem. He painted You can bootleg whiskey for twenty-five cents a quart using a wet media called Gouache. Gouache is an opaque paint made of Chinese chalk and water colors. This type of paint has no transparency. Gouache isn’t a paint where the brushstrokes can be

(4a-α, 7-α, 7a-β) -nepetalactone was predominated. Results showed drying methods had a significant (p < 0.01) effect on the essential oil content and its components (Table 1). Sun drying, shade drying, drying with 100-watt power of microwave radiation and the shade drying followed 3 hours the sun drying were reduced essential oil content when compared with fresh plant of catnip. In contrast the amount of essential oil was

output. 2) The sample was weighed and kept inside the chamber. 3) Weight of the sample was noted after each 2 min interval with the help of electronic balance after drying. 4) The dried material was taken out and tempering was done for 15 min, after that the sample is transfer to the fluid bed dryer to the second phase drying. 3.7.2 Fluidized Bed dryer The dryer was simple, compact and easy to operate. It consisted of a centrifugal blower, holding bin, heating coils, motors and thermostat control

capsule-filling machines can produce up to 200,000 capsules an hour and are also capable of filling in a number of different substances in a single process run (Stegemann, 2002). Spray drying involves pumping a concentrated liquid through a device that forms small droplets that are sprayed into hot air to force rapid drying and produce a fine powdered product. Many different products

adjacent concrete to settle and form crack over the restraining area. In exposed situations, this may increase the risk of corrosion of the reinforcement and pose a threat to durability of the structure. Cracks may develop further due to subsequent drying shrinkage, leading to possible cracking through the full depth of the concrete

The text tries to persuade possible customers to use their services. Text B, “A Perfect Pet Comes Frozen to the Core”, is a newspaper article from The Sunday Times. It was written on the 6th of October in 1985. The text discusses the act of freeze-drying dead pets and interviews someone who performed this act. While both texts deal with the aftermath of dead pets, both discuss a completely different topic. The purpose of text A is to persuade the reader to use their services. You can see this from

in childcare for the children and staff, as it’s the most effective way to stop the spread germs. By washing your hands with soap and water removes both dirt and germs from the hands preventing the transmission of disease. Hand drying is just as important as washing, drying your hands thoroughly as it also helps remove any germs that may have not been rinsed off. Its also a good idea to place an alcohol based hand rub at the entrance of the childcare centres, by the doors of each room and in staff

For all adhesives, decontamination of contaminated cured adhesives by “washing and drying” resulted in the lowest bond strength. But, each of the two decontamination procedures, “slow drying” or “washing, drying and reapplication of adhesive,” was acceptable. They related this result to removal of the adhesive layer during washing and drying, leaving a surface that was demineralized but non-infiltrated by monomers. Scanning electron microscopic evaluation also

Keeping a clean car can be a hassle for some, but it doesn’t have to be a difficult process to make your car look good! There is a saying that goes “ your car represents you” meaning how you take care of your car is how you take care of other things in life. Keeping your vehicle clean is one way you can start good habits of cleaning and staying clean. Although, cleaning a car can be easier said than done, if you follow these simple fourteen steps correctly you will have your car looking like new

et al. [90] the ability of sucrose in maintaining particle size following reconstitution after freeze drying was expressed, with the initial size (162.1 ± 0.8 nm) remaining almost unaffected after freeze-drying (162.7 ± 1.1 nm). This was reiterated in a study carried out by P. Fonte et al. [72] showing that sucrose maintained the particle size of the insulin loaded nanoparticles after freeze-drying, whilst maintaining the overall zeta

refluxed in a flask connected to condenser and drying tube. As seen in the mechanism, maintaining a dry condition is important to avoid the Grignard reagent from attacking water, which will result in loss of the bromine. It is important to reduce the amount of moisture and water vapors to avoid destroying the Grignard reagent, which is essential to the synthesis of 2-methylhexanol. Hence, a calcium chloride and cotton were filled inside a drying tube. The condenser was wrapped with parafilm and

Conventional energy sources based on natural gas and oil has to be proven highly effective drivers of economic progress, but the same time damaging to human health and environment. They are cyclic in nature, due to the effects of oligopoly in production and distribution. A transition to renewables-based energy system is looking increasingly as the cost of solar and wind have dropped substantially in the past few years, and continue to decline, while the price of oil and gas continuously vary. In

tannins salt insoluble. Caffeine is more soluble in dichloromethane (14g/100g) than in water (2g/100g). Caffeine will dissolve in the dichloromethane phase while tannins salts remain in the aqueous phase. Addition of sodium sulphate will act as a drying agent and evaporation of the dichloromethane solution would yield pure caffeine which is white in

ethanol.This was followed by a 20 min incubation and 15 min centrifugation at 11 000 × g at 4°C. The pellet was washed with 1.2 mL 75% ethanol, followed by centrifugation at 11 000 × g at 4°C for 10 min.The supernatant was discarded. The RNA pellet on drying was then dissolved in 50 μL DEPC-treated, sterilized ddH2O, and stored at -80°C then

The story of Noah from the Qur’an starts off with Noah warning the people to worship God or else there would be punishment approaching their way. Noah was quoted saying, “O my people! Worship God! You have no other god other than Him. Truly I fear for you the punishment of a tremendous day” (Qur’an, The Heights, 7:59). The people of that time period replied back saying that Noah is wrong and ridiculed him. Noah went to work to build an ark. The Ark was built from a tree that grew for forty years

crime, and hunger. To elaborate, if a person’s wound is left open, they are prone to infections, tearing of the skin, and drying and clotting. Therefore, a wise solution to this would be sutures, better known as stitches. This is similar to the usage of community gardens to solve blight (like wound infections), crime (similar to tearing skin), and starvation (identical to drying). My purpose in writing this essay is to explain how community gardens operate to solve these various problems. Just like
