Chemistry Task 2 Portfolio Outline and examine some uses of different metals through history, including contemporary uses, as uncombined metals or as alloys. Metal/Metal Alloy Uses Throughout History Copper - Used to make ornaments and domestic utensils in historical times (not as tools as it is a soft metal) - In modern times used in electrical wiring, pipes and plumbing fittings, jewellery, decoration, - This is due to its malleability, ductility and good electrical conductivity. Bronze…
The rivets and grommets are made of copper and come from a company in Missouri, that acquires it's raw materials from U.S. mines. In 2014 the United States produced 1.37 million metric tons of copper, worth $9.7 billion, making it the world's fourth largest copper producer. Arizona, Utah, New Mexico, Nevada, and Montana are the top five copper producing states. The process of extracting copper from copper ore varies according to the type of ore and the desired purity of the final product. The…
Steven Joseph Chem 111 Eli Munoz 3 October 2016 Chemistry Technical Abstract: The Copper Cycle Steven Joseph*, Christian Contreras Introduction: This experiment consisted of studying the copper cycle. Along with its overall significance to biological systems, reactions were done in order to test the types of reaction types associated with copper. In addition, vacuum filtration methods and detailed observations were taken on how copper reacts with different chemicals as it is constantly heated…
A leather jacket, is just a leather jacket, until a punk makes it their own. Leather is a symbol in punk subculture that showcases their beliefs and opinions to the rest of the world. While many abhor the fashion trend, the punks find enjoyment in shocking the masses with their radical and unconventional apparel adorned in spikes, studs, chains, and intentional rips. They look for cast-off garments often from thrift stores, Good Will, and Salvation Army, especially black clothing and…
trying to capture and promote a design that not only targeted young adults but also teenagers. In my dusk jacket I wanted to display the racial and stereotypical profiling of minorities. I also wanted to incorporate Chinese culture. Contemplating an idea for book jacket cover was very difficult. I did not know what I wanted my cover to look like. So, I did some research. Looked at book jackets and decided how I wanted mine to be original but still appeal to the same demographic. Advertising…
In the lesson Cindy and I had planned for the Week 6 Tutorial for the Unit LAN1260, the specific learning goal was to present and justify a point of view relating to a prediction about the content of a text and to clarify the understand of content as it unfolds in formal and informal situations allowing student’s to connect ideas of their own experiences presenting and justifying a point of view. Students were introduced to the key learning goal and were given an example of the task to be…
pushed her through the air my hands over my head. Kimberly was very slim but was still tall and could hold her weight that high in the air. One thing I can say I could never do. As I held her foot over my head as she hit her famous scorpion and kick full down into our arms. We have this in the bag I know we do. As we walked into the building I can feel my heart racing in my blood pumping. I always get so anxious every time we come in the competition. As we walk through the sea of girls I…
The 1950’s was a period were being rebellious and outspoken was popular for young adults. The “Greaser” was the most popular and rebellious title a young adult could have during the those times. A “Greaser” is well known by wearing a leather jacket, plain white t-shirt, tight blue jeans, and a greased up hairstyle. In Tom Coraghessan Boyle’s story “Greasy Lake”, he tells us the story of three 19 year olds trying to spend a summer night living a “Greaser” lifestyle and getting into any trouble…
During the sheet metal operations, e.g. bending, stamping, drawing and stretching, among the various possible modes of failure, such as wrinkling, scoring, the tearing of a polycrystalline sheet metal is the most common, resulting from an uneven or exorbitant amount of plastic deformation forming a localized neck and therefore limiting the formability of the polycrystalline sheet metal. In the sheet-metal forming industry, it is therefore, of high importance that the failure of metal sheets due…
Based on Physical and Chemical Properties, Determination of Identities of Zinc, Sodium, Beryllium, Copper and Boron By: Shreya Uppala, Lizzy Jolly, and Kyrie Harrell Results: The first element we tested was zinc. Since zinc was already known, the density was stated to be 7.13g/mL and the hardness was a 2.5 based on the Mohs Hardness Scale. No magnetic attraction was observed when in contact with a magnet. Zinc had a shiny appearance with a light gray color and the strips of zinc added to…
