Compound W, also called 3,5-bis(4-Nitrophenoxy) benzoic acid or salicylic acid topical, is an over the counter wart removal medication. Compound W is a keratolytic (peeling agent). It is used to shed the outer layer of skin; because of this, Compound W is often used to remove corns, calluses and warts. Furthermore, it is also used in the treatment of acne, dandruff, seborrhea and psoriasis. Compound W works by increasing the amount of moisture in the skin and helps dissolve the substances that cause the skin cells to stick together which helps make the skin cells shed off. Compound W increases the moisture in the skin by using the hydrogen and oxygen in the molecule to create water. It also helps lower the level of secreted Ab42 and Nb25. Compound W is accessible to everything because it is an over the counter medication. The main manufacturer …show more content…
All the bond types in this molecule are covalent bonds because all the elements involved are non-metals. There are three carbon rings in the molecule and each carbon ring is connected with an oxygen. The inactive ingredients alcohol, camphor, castor oil, collodion, ether, ethylcellulose, hypophosphorous acid, menthol, and polysorbate 80. The active ingredient in Compound W is salicylic acid. Salicylic acid, also called ortho-hydroxybenzoic acid, is mainly used for pharmaceutical products such as aspirin and Compound W. The chemical formula for salicylic acid is C7H6O3. In 1838, an Italian chemist Raffaele Piria created salicylic acid from salicylaldehyde. This was the first time salicylic acid was ever prepared. Later on in 1860, two German chemists discovered an synthesis based on phenol and carbon dioxide. However, today salicylic acid is not made either of these ways. It is made from dry sodium phenoxide and carbon dioxide which is then followed by treatment with acid. Even though salicylic acid is prepared, it can be found in small quantities in plants of the genus
In the first section, the Synthesis of Aspirin, salicylic acid was weight to be 3.029 grams using mass by difference since it was weighed on a 150 milliliter beaker. 9.23 milliliters of the acetic anhydride and 14 drops of 85 percent phosphoric acid were added to this beaker. A Bunsen burner provided by the laboratory was then used to boil the just mixed combination by producing a flame underneath the positioned beaker on top, and then allowed to cool for several minutes after the Bunsen burner flame was terminated. Two quantities of distilled water were then added to this mixture to make it cool even further, which were 41 drops and 30 milliliters. After cooling for some time, this beaker was placed into an ice bath in order to start the crystallization process. A glass rod was used to scratch around the bottom and the sides to catch all of the crystallized Aspirin that was being formed during this whole process. Then, by using a Buchner funnel and filter paper, which was placed on top of the flask connected to a water aspirator with rubber tubing, the excess liquid was removed from the just scraped Aspirin crystals when the Aspirin was placed on the filter paper. Using a medicine dropper, the Aspirin crystals on the filter paper were washed with distilled water just so that any non-pure substances were removed from the crude product. When these crystals were then ultimately dry, they were placed on a watch glass and put into an oven for 30 minutes. Then they were weighed by mass by difference to yield 2.4667 grams of crude s...
Esterification was used to synthesize aspirin which was by reacting salicylic acid with acetic anhydride. To speed up the reaction, dehydrating agent and conc. sulphuric acid was present. The purity of a substance, which is the aspirin in this particular experiment, can be determined by the identification of its melting point.
Aspirin contains the substance acetylsalicylic acid (ASA), which can relieve inflammation, fever, pain, and known as a “blood thinner”. Aspirin was not officially trademarked until March 6, 1899 when the Imperial Office of Berlin made it official. It has been used for the last 110 years, but its natural form, salicylic acid has been around for thousands by Egyptians, Greeks, and Romans. Aspirin is available in over 80 countries and known as the best non-prescription drug. The most common use of aspirin is to cure headaches and use it as a pain reliever, but aspirin is known to prevent heart attack and strokes. It was first proposed in 1940, but wasn’t confirmed until 1970 when doctors would recommend taking aspirin daily [1].
A boy who likes to cause trouble and to run turned into an olympic runner. Just as he was about to break the record mile time and get a gold medal, suddenly a historic day turned his life into a day to day survival story at sea. It then changes forever when a Japanese plane brings him into a Japanese POW camp. The amazing man's name was Louie Zamperini and his amazing story is written and told by Laura Hillenbrand in the nonfiction novel Unbroken.
The Scarlet Letter and The Crucible both provide similarities about the characters within the Puritan community. Both books reveal similarities between Hester Prynne in The Scarlet Letter and John Proctor in The Crucible. Hester Prynne and John Proctor are not physically similar, but they are alike in some ways because their beliefs and emotions towards the Puritan law affect their reputation and determine the outcome of their future. Hester Prynne and John Proctor are not physically similar but both characters feel guilty for committing adultery, show integrity, they are courageous, and their deaths have left behind a legacy.
Growing up is a natural part of life. Everyone grows up. The loss of childish innocence and blind faith in what is said is one chief mark of growing up. Loss of innocence, however, presents itself in many forms, even to adults, and with it brings a greater understanding of the world at large. In literature, authors use the process to explore society and humanity. Through the characters’ loss of innocence, the authors of both To Kill A Mockingbird and Of Mice & Men discuss ideas of prejudice, family, and courage.
There he stands atop the stairs of the Lincoln Memorial, in the nations’ capital, at a podium, speaking to the world. The crowds faces full of hope. Ears opened wide and clear, for the Dr. is speaking today. He is speaking from the heart and telling the nation that he has a “DREAM.” Dr. King had a dream and as most people think that it is geared towards blacks and whites, it’s not. Dr. King wanted equality between everybody. He wanted freedom from racism and prejudice throughout the nation. He was very good in getting the emotional perspective of persuasion across to his audience. King was a very inspirational man; his words were so true and full of meaning. He spoke to everyone and got everybody involved. This is why people followed him and why I think this is the most persuasive piece we have read. He not only implies his wants but he carries along with him the wants and needs of every man or woman ever treated poorly because of the color of their skin or their beliefs. There is a certain unexplainable meaning and feeling when a man like King steps up in front of the world and says, “I have a Dream.”
Unbroken is the tale of Louis Silvie "Louie" Zamperini a former American war prisoner survivor. Unbroken shows how Zamperini survived and stayed strong in his darkest hours in the Japanese concentration camps of World War II. Unbroken is a very spiritual book that proves that not giving up, staying strong, and being motivated will help you in life. Louie Zamperini was able to overcome a lot of horrible experiences by keeping a positive spirit and mind (set). The point of my essay is that hanging onto bravery and remaining strong all the while being in the belly of the beast will help you survive.
One main idea of this book was that with the right mindset anything is possible. This is proven in the book when Louie is in the concentration camp and has to hold up a large piece of wood while having the Japanese guards stare at him. This shows that he had the mindset that he could outlast the guards and that he could overcome any obstacles in life.
Curriculum and instruction is impacted by assessment, and whether in the design, delivery or data interpretation processes, aligning these apparatuses is most challenging part of being a teacher. Teachers are called to exercise an alignment between assessment and curriculum, use assessment to guide instruction, and deliver assessment that truly evaluates achievement. Two forms of assessment used in the classroom, formative and summative possess important components, that track them into purposeful, designated uses. Even more so challenging as a teacher in using these two assessments is understanding how they work separately, together, and exploring how they might be used with and for each other.
Unbroken by Lauren Hillenbrand is written about the perspective of a young Olympic runner named Louis Zamperini. He is from Torrance, California. Life for him was normal until the he was called into service for his country. It was then when one of his most unforgettable experiences developed.
Background Information Aspirin is an analgesic (pain relieving) and an antipyretic drug (a drug that lowers body temperature). The main constituent of aspirin is 2 - ethanoythydroxybenzoic acid, also known as acetylsalicyclic acid (shown below right). It was originally made from just salicylic acid (which is found in the bark of a willow tree) when used by the Ancient Greeks to counter fever and pain, but its bitterness and tendency to irritate the stomach caused problems. These were resolved by the German chemist Felix Hoffman, who made the acetyl derivative of salicylic acid in the
·Aspirin (salicylic acid acetate) is an anti-inflammatory (decreases swelling and inflammation), anti-pyretic (fever reducing), and anti-platelet (decreases platelets in the body to thin blood). Many heart treatment patients take an aspirin a day to prevent blood clotting. However, if aspirin is taken in large quantities over long periods of time, it may cause gastric ulcers or other internal damage. The molecular formula of aspirin is C9H8O4. Some examples of Aspirin are Bayer, Ecotrin, and Aspergum.
Divergent is all about identity and finding where you belong and where to fit in. Divergent takes place in a dystopian future society in which there are 5 factions that one must choose from or end up becoming ‘factionless’. ‘Factionless’ people are people who didn’t fit in the system, they have no identity, no places to live and the lowest social status. The protagonist had a sense of bravery ever since she was a child which I believe makes here a great character.
