Coursework 4 Copper Name of student: Alfiya Ospanova Tutorial group: G Copper is one of the earliest elements explored by humanity. Due to the special red shade it was easy to find in ancient times. The metal was named according to place where it was found‚ the Cyprus islands. Copper produced in massive stars and spread in the world as minerals like chalcocite and chalcopyrite (sulfide of copper)‚ azurite and malachite (carbonate of copper)‚ cuprite (oxide of copper).

1.Rinsing Raw Meat and Poultry. Dean Cliver‚ PhD‚ an Institute of Food Technologists spokesperson on food and kitchen safety‚ says the USDA has backed off the idea that meat and poultry should be washed or rinsed—in fact‚ the organization’s website says there’s no need to do so. “Sometimes you may buy a chicken‚ and it has salmonella. If you cook it thoroughly‚ it would kill it‚” Cliver says. “Washing it might spread the salmonella around.” 2. A Greasy Range Hood and Filter. Captain Peggy Harrell

A Sequence of Chemical Reactions: Transforming Copper Briefly describe. a) Why must you carry out the oxidation of Cu with HNO3 in a fume hood? Concentrated nitric acid is a toxic oxidant. Avoiding skin contact or inhalation is highly important. The reaction between Cu and HNO3 produces NO2‚ a toxic brown gas; therefore working under the fume is necessary in order to prevent inhaling the toxic gas. b) Why you should be particularly careful when you work with 3 M H2SO4 solution?

sulphides in contact with air and water produces sulphuric acid which reduces the pH of water. The result of these reactions is increase in the solubility of heavy metals and consequently pollution of water resources. The Sarcheshmeh copper mine is one of the largest porphyry copper mines in the world which is located in south-eastern Iran. Chemical analysis of over than 600 water samples taken from streams and springs in the mining region and surrounding area of pit showed extensive changes in water quality

HEAT TREATMENT OF COPPER AND COPPER ALLOYS COPPER AND COPPER ALLOYS: Copper and its alloys are widely used in many products that are used in our everyday life. They have excellent properties such as electrical and thermal conductivity good strength. They have high corrosion resistance and fatigue resistance. Copper is a non-magnetic material. Pure Copper is soft and used widely in wires and cables and is extensively used for passage of electricity. Copper is used in the building construction.

6: The Copper Cycle CHEM 101 Lab-M/630 As an investigation of the copper cycle lab group 6 conducted an experiment on 6 October 2014 at Arizona State University laboratory that would demonstrate the cycle of reactions that copper (Cu) can produce when introduced to with other substances/reactant. The purpose of the investigation was to notice the transformation of a specific quantity of copper wire (g) as it undergoes its coordination reactions until a reduction method would yield copper (Cu) again
