Copper Cycle Lab Report Ameerah Alajmi Abstract: A specific amount of Copper will undergo several chemical reactions and then recovered as a solid copper. A and percent recovery will be calculated and sources of loss or gain will be determined. The percent recovery for this experiment was 20.46%. Introduction: The purpose of this experiment is to demonstrate the different types of chemical reactions, those including Copper. There are different types of chemical reactions. A double displacement reaction

P1 Predict the products that form when solution of electrolysed and molten electrolytes are electrolysed Electrolysis Chemical change which is produced by passing an electric current through a conducting solution or molten salt Electrolyte A substance which is able to ionizes ad conduct electricity In order to predict the product of the electrolysis but before we do that we need to know what it is and how does it work. Electrolysis, it is a method to separate bonded elements and compounds by

Chromium is a transitional element, with three stable forms. It is a neutrally charged stable form, but naturally occurs in the environment. Trivalent chromium is a +3 charge stable form of chromium that can be naturally oxidized from its neutrally charged version, occurring in the environment (Mertz et al., 1974; Barrett et al., 1985; Alexander et al., 1990). Hexavalent chromium is a +6 charge stable form of chromium which is the product of industry, and it is very toxic to living things. Hexavalent

greenish. It is also used to dye ceramics and is used in forming many alloys. Inhaling this substance can cause lung cancer and other serious effects. - When Nickel metal reacts with Hydrochloric acid, it forms Nickel dichloride (NiCl2) which is for electroplating -Nickel tetracarbonyl (Ni(CO)4) was discovered by Luidwig Mond when he was trying to find a way to isolate nickel the metal. This substance is very toxic at room temperature but when it is heated, it turns back to nickel and carbon monoxide

(3000 characters) My goal is to conduct research in the exciting field of quantum information science, and especially in the area of quantum computing. First envisioned

Homo sapiens are organisms of miracle. Not only can we perform multiple tasks, but we are blessed with the ability to learn multifarious skills, improvise and make things we need. But the above are just so disposable a quality as compared to our human nature. Adam Smith gave us an insight to human nature – the nature which induces our predecessors to start forming the society we are in – “the propensity to truck barter, and exchange one thing for another” (The Wealth of Nation, Book I, Chapter II

bedrock and soil. Chromium weathered from the rocks is deposited on the soil and groundwater. Chromium is also generated anthropogenically from various industrial processes which includes electroplating, leather tanning, wood preservations, manufacturing of dye, paint, paper, petroleum refining processes, metal finishing, alloysteel manufacturing, and lasers(Owlad et al., 2010). According to BIS (Bureau of Indian Standards) and USEPA the maximum acceptable limit for Cr(VI) in drinking water is 0

Thomas Edison is an American inventor and businessman, who has been described as “America’s greatest inventor.” His tireless work efforts and dedication to science not only helped him to create inventions that have advanced technology , but also become an inspirational figure for Americans. His improvements and inventions on objects that were already invented helped the lives of over millions of Americans. He helped to build America’s economy during some of its more vulnerable years as a new nation

Erin Brockovich is a 130 minutes self-titled film impersonated by Julia Roberts, directed by Steven Soderbergh and written by Susannah Grant. This film narrated the true story of thrifty, sedulous and tough woman, Erin Brockovich and her route on becoming a well-known legal clerk and environmentalist. Erin is a jobless single mom that has a debt of 74 dollars and has 3 kids, Matthew, Katie and little Beth. In order provide for all the necessities of her children she start rummaging

additional 500 to 600 that was unsuccessful or that was abandoned. Also he executed his first patent for his electrographic vote-recorder on October 13,1865 at the age of 29.Also his last patent was for a apparatus for holding an object during the electroplating process.Also during the World War I the U.S government asked if Thomas edison to head to the NAval Consulting board which examined

Cadmium is very toxic heavy metal and have adverse effect on human body it disturb enzymatic activities of cell , tissues and metabolic processes of human body(Irfan et al., 2013).it was first discovered in 1817. It is noncorrosive so it is use in electroplating and galvanizing.it use

In the past, in order to listen to music, one had to physically be in the presence of a musician performing and as such it could be rather difficult to hear music on a regular basis. This was, however, before advancements in technology began to allow for music to become more accessible. Technology has and continues to augment and advance music for the betterment of its accessibility and economic viability. For a long time, music and sound in general couldn't be recorded let alone played back in

inorganic materials from non point sources such as sewage, food waste, farm effluent, through drainage ditches, including artificial fertilizer residues, insecticides, herbicides, pesticides and farmyard waste, in addition from point sources such as electroplating, pesticide, fertilizer and beverage industries. Addition to these, disposal of dead bodies, discharge of industrial and sewage wastes and agricultural runoff, which are major cause of ecological damage and pose serious health hazards (Meitei et

Over the centuries,activated carbon has been used as an adsorbent and purify in water. In India, during 450 B.C. charcoal filter is used to treat water. It can be produced through the use of raw carbon resources like coal and peat, and Waste-product materials such as shells of coconut and sawdust.Activated carbon also called as activated charcoal is a carbon that undergone to processes so it will have small and low-volume pores that increase the surface area for adsorption. Two way to produce activated

in the environment found at low levels but it can greatly increase to high concentration levels due to the human activity. Most cadmium has been used for manufacturing nickel-cadmium batteries. Paint pigments, stabilizers in many plastics and electroplating industry are also the example function of cadmium. The cadmium present in the atmosphere usually from human activities especially smelting of non-ferrous metal ores, fossil fuel combustion and municipal waste incineration (ATSDR,

Chlorides of group || cations contain (Cadmium chloride, Mercuric chloride, Copper chloride and Bismuth chloride). 1- Mercuric chloride HgCl2:- It's poisonous odorless white crystalline solid, very toxic compound, and it's slightly volatile at ordinary temperatures. Parent acid and base: Hydrochloric acid HCl + Hg(OH) 2 Uses:- *Antiseptic and disinfectant in insecticides, preservatives, and batteries. *Antibacterial. * Obsolete substance. Preparation: Mercuric chloride can be obtained

In the periodic table lithium’s atomic number is 3. The atomic number describes the number of protons in the nucleus and the number of electrons in the atom when it is not ionized. (An ion is an atom where the amount of protons and electrons is not equal.) Lithium has 3 protons; therefore it must have 3 electrons when it is not ionized. The protons and neutrons together form the nucleus. Lithium has 3 protons and usually 4 neutrons since its atomic weight is 6.9 according to the periodic table

Since then, cosmetics has been part of the routine body care of many people. These products have had an immense improvement and are also a tool for beautification to the human body. Women used cosmetics to make them feel beautiful and confident. But could it also make them sick? Human beings can be exposed to high level exposure to toxins because of the environmental pollutants that we are exposed in thus, humans can have a heavy metal toxicity. Besides the exposure to environmental pollutants,

never invented weapons to kill.” As the 1920s were coming to an end so was Thomas Edison. He was beginning to slow down in his 80s, but not before he applied for the last of 1,093 U.S. patents, for an apparatus for holding objects during the electroplating process. Eventually, Edison and his second wife, Mina, moved to their winter retreat in Fort Myers, Florida, where his friendship with the automobile tycoon Henry flourished and he continued to work on several projects, ranging from electric trains
