The Effect of pH Level of a Liquid on the Rate of Corrosion of Copper wire In this experiment‚ I will be testing the corrosion rate of copper wire after leaving them in different liquids with different pH levels. By doing so I will be able to determine which pH level corrodes copper the fastest. I will conduct this experiment by pouring 250mL of different liquids with different pH levels in cups‚ followed by an iron strip placed into the cup. A stopwatch will be timing how long it takes the iron

There are four major factors that often contribute to the formation of hydrothermal copper porphyry: 1) readily available mineralizing fluid solutions that dissolve and transport metals‚ 2) openings in rocks which allow permeable flow of hydrothermal fluids and the metals that they transport in solution‚ 3) available sites within the fractured rocks which allow for deposition of the minerals from solution‚ and 4) the requisite chemical reactions that contribute to that deposition (Bateman‚ 1967)

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.

ABSTRACT Acid Mine Drainage (AMD) problems are the most important environmental problems in sulphide mines especially mines which contain pyrite. Oxidation of 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

Abstract With the increasing competition‚ it is imperative for organizations to bring about managerial innovation and focus on managerial effectiveness. Studies indicate that only 27% of success at work is contributed by an employee’s Intelligence Quotient‚ the rest of it being contributed by Emotional Intelligence. This paper attempts to study the role of Emotional Intelligence in Managerial Innovation and Effectiveness. The results of the study indicate a positive correlation between Emotional

Web 2.0 and public relations “The greatest craving of humans is to express and to be understood” Humans love and desire connection with others. The boom of internet age is the proof of this desire. Internet survived the dot com bubble and the world saw the rising of giants like Google and Yahoo who thrive on information sharing and “connecting” people through chat rooms and social networking. The desire to express finds its manifestation through newer channels like blogs and social networks which
