Liquid-liquid extraction

The organic care hand wash had 2cm worth of inhibition zone, dettol hand wash had 1cm, palmolive had 0.9cm and dettol santisier had 0.8cm. In terms of which one was the most ocst efficient, dettol hand wash cost $2.00, while organic care costs $4.00. The hypothesis was refuted, as it was said the popularity of the product would dictate its effectiveness and efficiency, yet the most popular product is dettol. Dettol is seen in everywhere, on hygiene posters, tv ads, in public bathrooms etc., and…

To begin changing the oil on a 1994 Formula Firebird, the vehicle must be parked on a flat surface and turned off. The motor will need time to cool, so as not to burn whoever is performing the oil change. During the time period in which the engine is cooling down, place a three-ton capacity jack under the car and position it below the frame behind the front wheel on the driver's side of the car. Then, push down on the lever of the jack until the car has been raised enough for a person to crawl…

1. Describe the function of the scrotum in protecting the testes from temperature fluctuations. Scrotum is an external sex organ. The scrotum is a pouch like structure made up of skin. It has 2 main functions. It protects the testis and maintains 2-3oc temperature lower than body temperature, which is very important for spermatogenesis. The scrotum also contains numerous blood vessels and nerves. The cremaster muscle present in the scrotum contracts and pulls scrotum closer to the body whenever…

Did you know, if you add salt or ice to anything cold the temperature drops? In my experiment, I wanted to find out if different materials impact the rate of ice melting. Before starting this experiment, I know sugar and salt dissolve in water and sand turns into mud. I predict that the results of this experiment will be that the sugar and salt will make the ice melt at a faster rate than the sand because sugar and salt dissolve in water and sand does not. To complete this experiment I will…

Introduction: If you have paid any attention to the news lately, you will hear a phrase that is becoming more and more widely used to describe one of the main dangers of hydraulic fracturing (fracking) in Alberta. This phrase is called “induced seismicity.” Numerous tremors have been felt in Alberta within the past six (6) months and a concern is growing that a large earthquake will be triggered in the immediate future. Residents of Alberta are worried that their homes and livelihoods will be…

really is evaporation? Most people just know evaporation as the change of state from a liquid to a gas. Yes, it is that but it is also the most common way to put these liquids back into our atmosphere. Another thing is a lot of people think there is no point to evaporation…

Subtopic #1. Topic Sentence: Fracking has commercially benefited private citizens, in terms of economic gain. However, the actual chemicals used in the process could harm them physically. Artifact: Graph depicting the health effects of hydraulic fracturing chemicals. Artifact Caption: Profile Of Health Effects From Fracking Chemicals Artifact Citation: Graph of oil Chemicals Health Effects from; Center for Western Priorities. “Fracking and Water Quality.” Center for Western Priorities, 26 July…

To begin with, fracking is is a slang term that refers to hydraulic fracturing which is the procedure of creating fractures in rocks and rock formations by injecting fluid into cracks to force them open thus releasing oil and natural gas. In this essay I will be citing from multiple sources and explaining the pros and cons of fracking. First of all, fracking is very harmful to the environment. According to the New York Times, “The fracking cocktail includes acids, detergents and poisons that…

The difference between Oceans with salt, and freshwater lakes with no salt, is that salt water takes longer to boil because of the molecular properties. The salt increases the boiling temperature, which makes the tendency for the water to evaporate is greater than the tendency for the water to remain on a molecular level. When the salt is added, the phenomenon known as “boiling point elevation” occurs. Which, involves the old school chemistry the solute, the solvent, and the solution. Chefs…

Fracking is affecting you and everybody around you, whether you realize it or not. Fracking is the process of drilling down into the earth before a high-pressure water mixture is directed at the rock to release the gas inside. Water, sand and chemicals are injected into the rock at high pressure which allows the gas to flow out to the head. Fracking can be used to obtain fossil fuels, methane, and natural gases. Many countries like: France, Bulgaria, Germany, and Scotland have banned fracking…
