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)

Polaroid in 1996 is a popular topic of discussion amongst finance specialists due to the complex issues involved. Specifically‚ after a long period of unsuccessful moves to discover a sales vehicle that will enable the company to resume its success of the early 1970’s‚ in the mid-1990’s the company is found on the verge of bankruptcy. Its new CEO Di Camillo is facing a very large debt‚ which is due to mature in six years. Furthermore‚although the company does not perform well in the US market‚ there

Zinc and Hydrochloric-Acid Written By Kahlil Zione Date:02/02/05 Abstract: We observed the reaction between zinc and hydrochloric acid and recorded it in a table and learned wether the percentage of zinc is effected by the amounts of both substances added to the solution. Introduction The purpose of this experiment is to determine if the amount of zinc and hydrochloric acid will effect the percentage of the zinc in the out coming solution. We are reacting zinc metal with hydrochloric

Introduction of Lab 5: Analysis of a Zinc: Aluminum Alloy The analysis of a metal alloy was designed to learn how to use the Ideal Gas Law (formulas listed below) in a laboratory setting in relevance to acquiring moles of gas created‚ thus giving us one step closer to finding the molar mass. The importance of the Ideal Gas Law‚ as well as the other gas laws‚ is that it signifies the relationship between the properties of an ideal gas. These properties assist in the explanation of the Kinetic Molecular
