Lab Report Title: – Osmosis Visking tube lab Research Question: Does increasing the level of sucrose increase the procedure of osmosis? Introduction: This experiment is called the osmosis visking tube. This experiment is to investigate the relationship between solute concentration and the movement of water through semipermeable membrane by the process of osmosis. The purpose of this The Visking tubing apparatus establishes the osmosis procedure. The Visking tubing is a semipermeable membrane

To purify and isolate trimyristin from a nutmeg, the sample of nutmeg was mixed and refluxed with dichloromethane before isolating and purifying the trimyristin through vacuum filtration and recrystallization. After refluxing the solution of dichloromethane and nutmeg, an intense amber colored solution was recovered. Through the process of vacuum filtration and recrystallization, a white, powdery and clumpy sample of solid trimyristin was collected. Of the 8.004 grams of nutmeg utilized in the experiment

Air Filters: Chevy Corvette, Cadillac STS, Chevy Silverado 1500 Your engine breathes just like you do, which means that it needs continuous clean air sent to it in order for you to get the best performance from it. The air filter is responsible for catching outside pollutants and other airborne contaminates and keep them from clogging up your engine. A clean air filter will keep dirt from getting into your engine and causing undo wear and tear on it. Dirty air makes the engine run rough and decrease

(1) The purpose of the separation lab procedure was to help my group members and I successfully formulate our own plan before completing the experiment, handling multiple materials and substances, etc. It acted as a step-by-step plan that guided us throughout the experiment and ensured that we were well prepared ahead of time (ie. knowing what kind of materials were necessary and gathering the correct measurements of each substance); this made the experiment day much less hectic for all of us. It

BS1003 – Organic Chemistry Practical 1 Laboratory Report Name: Tristan Chan Yew Kit, U1640436J (T8) Effects of Dichloromethane(DCM) in Extraction of Caffeine from Tea Leaves Purpose To investigate the ability for Dichloromethane(DCM), a moderately polar organic solvent, to extract aqueous caffeine molecules, originating from Tea Leaves suspended in water. Introduction Caffeine, defined chemically as 1,3,7-trimethylxanthine (C8H10N4O2), is an alkaloid that can be found in tea leaves, coffee and many

Lab report Experiment 6 The synthesis of Alum Lingrui Ge Oct 18th 2015  Purpose: discover the synthesis of alum. Materials: two 250 mL beakers, 400 mL beaker, 25 mL or 50 Ml GRADUATED cylinder, Buchner funnel and filter flask, watch glass, glass stirring rod, lab burner, ring stand, ring, wire gauze, hot plate, wash acetone, Aluminum foil, 3 M sulfuric acid solution, KOH, 50% enamel solution, ice bath, balance, boiling chips, gloves, pipe cleaner. Process: get and wear goggles, set up a Buchner

The impurities in the solution easily travel around the large chunks of alumina, whereas if the alumina was crushed, more of the impurities would be filtrated out of the solution. Another improvement that can be made is to use a longer column to filter the aspirin solution through. A longer column will allow for further filtration of the solution. One last improvement that can be added to this experiment is to use TLC chromatography, instead of column chromatography, in order to separate out the

Because flamingos can use different feeding methods and can filter selectively, and because some food items (algae, slime) are processed faster than others (seeds, mollusks), in most cases, the relative proportions of items consumed are not known. Flamingos of the same species, in nearby bodies of water, can be

Currently one of the most common and biggest issues all over the world is wasting water. We waste uncountable amount of water every day. There are many major issues behind this wastage but a messy toilet flapper is one of them. If you are unable to select the best toilet flapper for you then there is high chance that your flapper will be broken or ruined after a few days of installation. This will be of great loss and there would be a huge amount of water wastage and it would cause huge water bills

Competitive sports should Not be Played “I've been all too familiar with accounts of N.F.L veterans exhibiting Alzheimers-like symptoms in their 40s,” says Adam Buckley Cohen of the New York Times. Many people playing sports are experiencing severe injuries.Competitive sports are sports that include physical contact. The sports include football, lacrosse, soccer and baseball are some. And there are over 45 million kids play competitive sports according to Jay Atkinson from The Boston Globe. Competitive

1729, a Papist infected Ireland was being devoured by the taxes that the British placed on them. The taxes were turning into what once was a glorious place into ruins. Jonathan Swift, an Englishman and Irish sympathizer, realized that someone had to do something to wake up the British. This lead to the creation of A Modest Proposal, a pamphlet heavy with irony and juvenalian satire, which was how Jonathan Swift planned on compelling the British to do something about the poor situation in Ireland

Part Two: Poetic Devices Poetic devices are used extensively in Demi Lovato’s song “Skyscraper.” In this song, Lovato uses personification to show her depressed feeling. For example “Skies are crying, I am watching” (line 1). Since skies don’t actually cry, this indicates that an inanimate object like skies is given a human characteristic like crying, however, this shows that Lovato is referring to rain as crying since rain represents an emotion of sadness, which explains her depressed mood, and

Fire and Ice- Robert Frost In his poem Fire and IceRobert Frost compares and contrasts the two destructive forces: fire and ice. Frost presents the reader two options for the end of the world, either in hot fire or in icy cold. Although Frost chooses fire for the end of the world, he gives a fair comparison that ice could be the victor of the world's destruction. The theme presents itself with Frost taking the position of fire. Frosts describes his view toward fire in the third and fourth lines

In 1729, Jonathan Swift wrote possibly the world’s most ironic essay entitled, A Modest Proposal. Swift implies that poverty in Ireland can best be resolved by selling the children of the poor as food for the wealthy. Swift argues that children could be sold into a meat market as early as the age of one, which provides income to poor families because it saves them the costs of nurturing so many children. Throughout his entire essay, Jonathan Swift utilizes irony and satire to convey his sardonic

Jonathan Swift’s “A Modest Proposal” is a very interesting take on how the Irish government should cure the famine that the country was then facing. However, the entire proposal was completely bizarre, and the whole point of the essay was to bring attention to the idea that they needed a solution to the all the problems they were experiencing but the proposal was definitely not it. He even had a strongly developed plan as to how his proposal would work which makes the reader feel as if he is serious

Minority stress identifies chronically high levels of stress faced by members of stigmatized minority groups. It may possibly be caused by a number of factors, including poor social support and low socioeconomic position, however the most well understood causes of minority stress are interpersonal bias and discrimination. Indeed, several scientific studies have proven that minority individuals experience a high degree of prejudice, which causes stress responses (e.g., high blood pressure, anxiety)

When going down the road some diesel trucks go by blowing black smoke, well this is because it is tuned to use a fuel rich mixture. Also it does not use Diesel Exhaust Fluid. Diesel is a chemical product (“Diesel Exhaust Fluid Product Specification Sheet.” Graincofs, ). Diesel Exhaust Fluid (DEF) is an exhaust limiting fluid, one drawback of using it is having to pay for it, but the pros outway the cons. It has started to be used recently. Since it is new it has become very controversial. The fluid

LOSS, GRIEF AND HEALING As human beings, we suffer losses of many kinds and sizes in our life time. While some of these losses are small and do not hurt much, some are big and hurt deeply. Those that are accompanied by pains that are difficult to bear include the loss of a loved one through death or divorce, cheating or unfaithfulness in a trusted relationship or loss of good health when a diagnosis of a terminal illness is made. In all these instances of loss, pain and grief are experienced and
