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)

of CuSO4•H2O. It was strong enough to oxidize iodide ions to Iodine. The analyte was needed to be isolated‚ and we did this by precipitating it out of the solution. To precipitate out Cu (II) ions‚ NH3 was added dropwise – this is to avoid having an excess amount of NH3 in the solution which would form [Cu(NH3)4]2+that could interfere with the reduction of Cu2+and could change the pH of the solution that could also interfere‚ this time‚ the reaction – a basic environment would make the reaction

CHAPTER 1 The concept of ‘Postmodernism’- A Theoretical Approach It is a cliché by now to say that we live in a postmodern world‚ and it is true that the word ’postmodern’ has become one of the most used‚ and abused‚ words in the language. Still‚ it is striking that not many people can say with assurance what this term actually means and involves. Some theorists suggest that ‘postmodernism’ refers to a mood or an attitude of mind‚ others define it as a literary‚ cultural

CHEMICAL REACTION (SYNTHESIS REACTION‚ DECOMPOSITION AND SINGLE REAPLACEMENT REACTION) Purpose : 1. To identify the chemical changes 2. To observe the effect of temperature of a chemical reaction. Theoritical basic : A chemical reaction is a process that leads to the transformation of one set of chemical substances to another. Classically‚ chemical reactions encompass changes that strictly involve the motion of electrons in the forming and breaking of chemical bonds between

and a salt bridge. In a galvanic cell one metal can undergo reduction and the other oxidation. A typical galvanic cell is based on the spontaneous redox reaction: Net Ionic Equation Zn(s) + Cu2+(aq) → Zn2+(aq) + Cu(s) Half Equations Zn(s) → Zn2+(aq) + 2e– Cu2+(aq) + 2e– → Cu(s) The anode will undergo reduction (Zinc) and the cathode will undergo oxidation (Copper) The two half cells must be physically separated so that the solutions do not mix together. A salt bridge is used to separate
