Copper sulphate

4. Describe the procedure for extracting copper from one of its ores. Include relevant chemical reactions, equations and energy considerations involved. Extraction of copper from chalcopyrite (CuFe2) occurs using processes such as: mining & crushing, froth flotation, roasting & smelting and electrolytic refining. Mining the ore Copper ore contains approximately 0.5% copper and 99.5% unwanted rock. To help separate the mineral copper from the gangue (sand, rock and other impurities), the ore

The explicit journey through the history of Patera The Patera found in Greek South of Italy during the Archaic period c. 500 BC. Was a shallow pan made from bronze with a Kourous figure as it handle. This research essay will work to prove how the form of the Patera served a greater purpose to it functions through its significance journey through the craftsmanship of bronze, superior status of the Kouros and multipurpose usage it served. The bronze material which the Patera was crafted from is a valuable

Alchemy is used to change one element into another and make material from existing elements. Most of the original alchemists in Egypt tried to change common metal such as iron and lead into gold. It is a quest that has been interesting for people for thousands of years. Although most alchemists want to produce gold, many other alchemist use alchemy for medical purposes. They make medicine by using alchemy and some of the alchemists want to create a panacea which can cure any disease. ("Magic"). Because

Conservation of mass: How is copper transformed in chemical reaction? There were 3 objectives for this lab they were demonstrate that mass is conserved in chemical transformations, practice balancing out chemical equations for reactions observed in the lab and practice the skill of recognizing chemical reactions and making detailed observations. Part A of lab (preparation of copper (II) nitrate from copper metal). Weigh out ~ 0.2 g of copper foil pieces (record to the nearest .001 g) into a weigh

     Weil 1      Copper is one of the earliest elements known to man. Because of its distinct red color, Copper is very easily identified. In the ancient times, copper could be found lying in the ground in its unattached state without interaction to other substances. Copper and its compounds have many uses in today’s society. Copper has many chemical properties that make it unique. The Atomic number of copper is 29. An Atomic number is a measure of the amount of

Copper in Silver Nitrate Lab: Making Silver Sabrina Kate S. Carranza – Chemistry Hour 6 I. Purpose: The purpose of this experiment is to distinguish the relationships between reactants and products, in addition to expanding on concepts such as single displacement reactions, mole ratio values, moles to mass, theoretical yields, limiting reactants, excess, stoichiometric relationships and percentage errors. II. Hypothesis: /3 -If the copper metal is submerged in the silver nitrate solution

Teaghan Hignett March 15, 2015 Mr. Cho SCH3U Metal Reactivity Series Lab 2015 Question: What is the relative reactivity of aluminum, potassium, copper, iron and hydrogen? Introduction: This lab will introduce several key concepts surrounding metal reactivity as well as electronegativity and periodic trends on the periodic table. Electronegativity by definition is a measure of the tendency of an atom to attract a bonding pair of electrons. In a bond between atoms in a molecule, the atom that

experiment gather a lime, an orange, an apple, a zinc nail and a copper nail to model the essential parts of a battery. The zinc nail represents the negative charge while the copper nail imitates a positive charge. To measure this energy created in the fruit an analog multimeter was used. The procedure used is below. Collect the materials required for the experiment. Lay out a lime, a zinc nail, and a copper nail. Push the

Conductive polymers are a specific section under the broad range of polymers, that have the ability to effectively conduct electricity. They were discovered by accident in a lab by Hideki Shirakawa in 1974, yet their potential applications were not understood until early 2000s. They are made by doping with n-type and p-type which forces electrons to move throughout the material which normally would not happen because of a polymer molecular structure. They provide many advantages over metals because

Agriculture commodities include wheat, rice, pulses, cereals, edible oils, ground nut etc. Non- agriculture commodities includes crude oil, non ferrous metals like gold, silver, nickel, copper etc. My basic study of bullion and specifically of gold & silver led me to the fact that though India is the largest consumer of gold & silver. India largely has unorganized gold market. The government policies regarding the same have also
