Aluminium smelting

Anna McNamara - Year 11 Chemistry, Mr Thomson Chemistry Assessment: The Chemical Earth Gather information from secondary sources to distinguish the physical properties of metals and nonmetals. The key differences between metals and nonmetals are the physical properties which simply outlines the specific metal and nonmetal subdivision. In some cases semimetals or metalloids have a combination of properties which could classify them as being metals and nonmetals, hence the name semimetals. These properties

The bar scene was always the bomb in H-town, especially Carrington’s Sports Bar on South Main. It seemed that while some locations of other bars often changed, or closed down, the crowd inevitable remains the same from bar to bar. I would go out often after work to happy hour for a few drinks. One thing about me is I will jump on the highway in a hot minute for some excitement, if you know what I mean. I love the ladies and was fearless in my pursuit of them I especially loved the ones who

Introduction: In design and fabrication of metallic equipment and structures, often weight saving is often used to improve efficiency in in-service performance of the item. This paper will explore the interactive model of product development, which includes the important of: the uses of alternative materials on the design, fabrication and in- service behaviour of the item in order to provide awareness of how issue of the underlying principles of each of these weight saving alternatives and the

In this lab we recovered lead ions from a solution by creating a precipitate, lead(II) iodide that could be separated from the mixture. We create lead(II) iodide in this experiment by mixing a solution of lead(II) nitrate and a solution of potassium iodide. The reaction they create results in the bright yellow precipitate lead(II) iodide upon contact, Although this substance may be very interesting to look at, this and all other types of lead extremely dangerous to our health. Although contact to

Introduction: Bioavailability is used to describe when a substance is in a form that can cause a biological effect. The purpose of this experiment was to demonstrate a cycle of reactions involving copper. A specific quantity of copper will be transformed through a series of reactions and then recovered as solid copper. A percent yield will be calculated in order to determine the loss or gain of the solid copper product. Materials and Methods: In the first step of the copper cycle 0.2517 grams of

Analysis/conclusions In conclusion, the charge/roman numeral on copper in copper sulfate is 2+. The percent composition of copper in copper (I) sulfate was 40.58% and in copper (II) sulfate it was 25.46%. Later, I calculated that the percent of copper in the lab was 26.13%. This percent shows that copper (II) sulfate was used in this experiment because 26.13% was closer to 25.46% than 40.58%. If iron (II) sulfate and copper metal is the product of copper (?) sulfate and iron metal, then copper (

Andrew Peters Mineral/Rock Lab Report Introduction: In lab number 3, we learned how to identify some of the more common and important minerals. Using these identification methods helps us understand the environmental chemistry of an area to help us know what minerals are present in the soils, sediments and the rocks of an area, and how those are minerals are organized in the rock. In lab number 5, we looked at mineral interaction with water and acid. In this lab we were given 4 known minerals

1. Is primary aluminum production an attractive industry? Why or why not? I consider primary aluminum production is not an attractive industry because : a. The product is identical (ie, aluminum), all the companies procure the same resources to make production with same production line and process. The firms only differentiate in terms of controlling and lowering the variable cost in order to make a profit as a price-takers. Pricing is somehow fix in global level as aluminum is openly traded

LABORATORY REPORT 4 PREPARATION OF ALUM FROM ALUMINUM METAL Huy Nguyen October 2nd, 2012 The objective of the laboratory is to synthesize alum (KAl(SO4)2.xH2O) from aluminum powder and to determine the proportion of water in the alum crystals. Alum is a product from the reaction between potassium hydroxide and sulfuric acid. The reaction include several steps, as followed: Aluminum powder reacts with potassium hydroxide to generate Al(OH)4- ions and release hydrogen. 2 Al(s) + 2 KOH(aq)

Introduction Chelate means claw in Latin. Metal Chelation is a process when a polyvalent metal ion form covalent bonds with a drug and binds tightly to form a 5 or 6 membered ring. 5 and 6 membered ring structure are very stable because their bond angle has no ring strain. Thus, when a compound is chelated, it will not be able to pass through the biological membrane, in another words, it will not be metabolise by the body but to be pass through the renal without being absorbed and being excreted
