Preparation of an Ester Acetylsalicylic Acid (Aspirin) OBJECTIVE: To become familiar with the techniques and principle of esterification. DISCUSSION: Aspirin is a drug widely used as an antipyretic agent (to reduce fever)‚ as an analgesic agent (to reduce pain)‚ and/or as an anti-inflammatory agent (to reduce redness‚ heat or swelling in tissues). Chemically‚ aspirin is an ester. Esters are the products of reaction of acids with alcohols‚ as shown in the following equation using

Problem What effect does the different concentration of hydrochloric acid have to the rate of diffusion of agar that is dissolved with sodium carbonate and phenolphthalein? Introduction Diffusion is a process where the molecules intermingle as a result of their kinetic energy of random motion and is the net movement of like molecules down their concentration gradient‚ which is the energy inherent in their constant molecular motion makes them collide and careen outward from the region of higher

Discuss how separation has affected characters in this extract and how Samuels presents separation elsewhere in the play. Separation is a key theme in Kindertransport. This theme is explored in a variety of ways throughout the play‚ and even more thoroughly in Act 2 Scene 2. Kindertransport was a rescue mission‚ which took place nine months prior to the outbreak of the Second World War; being the title of the play‚ we get the impression that the play will include some sort of separation.

The overall experiment consisted of three smaller experiments as a result of the different properties chlorophylls possess and the need to test them individually to receive the most accurate results. Preparation for the lab began with selecting a medium to large spinach leaf and deveining it. Once the spinach was prepared‚ it was ground in 5 mL of 100% acetone‚ creating a green acetone extract. The extract was filtered through a funnel with a kimwipe and into a test tube. The volume of the filtered

The Need for a Separation Between Government and Religion As Benjamin Franklin (One of the founding fathers) once said‚ “When a religion is good‚ I conceive it will support itself; and when it does not support itself so that its professors are obliged to call for the help of the civil power‚ ‘tis a sign‚ I apprehend‚ of it’s being a bad one” (Nord 134). The separation between religion and government‚ also known as “the separation of church and state” has been a controversial topic‚ and has progressively

African Diaspora and the World After reading the short story “Diaspora” by Joanne Hyppolite‚ I got a vivid understanding of how diaspora can have an effect on one’s identity. Over the past month we have studied many theories and concepts concerning race‚ gender‚ and politics. There are three theories that capture the essence of Joanne Hyppolite’s worldview as a Haitian growing up in America: intersectionality‚ identity‚ and diaspora. Individuals oftentimes experience the theory of Intersectionality

The three conditions tested were the effect of peroxidase concentration on the rate of the experiment‚ the effect of pH of the rate of peroxidase activity‚ and the effect of temperature on the rate of peroxidase activity. During the lab‚ the lab group tested 7 test tubes‚ including 1 blank‚ with different amounts of pH 5 buffer‚ H2O2‚ Peroxidase‚ and Guaiacol. After the certain amount of mL per substance was mixed‚ the absorbance readings for the effect of peroxidase concentration were

“There should be a wall of separation between church and state” I believe in the wall of separation as originally intended‚ as a reference describing our First Amendment right of freedoms not prescribed by government. The term “wall of separation” first came about with Jefferson’s response letter to the Danbury Association in 1802. The letter was in regards to why he would not declare national days of fasting and thanksgiving as done by Washington and Adams before him. In the letter Jefferson brings

By close analysis of the extract‚ taking account of narrative methods‚ show how effective you think McCabe is in presenting the outsider Francie Brady’s alienation and separation from society. In ‘The Butcher Boy’ Patrick McCabe transforms‚ according to John O’Mahony‚ “the microcosm of the small town‚ a neglected and disparaged corner of Irish experience into an arena for burlesque humour and biting satire.” “McCabe is a true original‚” says critic and novelist John Banville. “Like Roddy Doyle
