Making an Activity Series of Metals using different Solutions Purpose/ Hypothesis: The purpose of this lab was to clearly identify the reactivity of magnesium‚ zinc and copper. The metals reactivity will be exemplified as it will be tested with different solutions such as zinc sulfate (ZnSO4)‚ copper sulfate (CuSO4)‚ hydrochloric acid (HCL)‚ magnesium sulfate (Mg2SO4)‚ iron (II) sulfate (FeSO4) and tin (II) chloride (SnCl2). This will allow us in creating an activity series to visually see the reactivity

too brittle to use for structural materials. 2. A) Describe the uses of brass‚ steel and solder and 2 other alloys of your choice‚ and explain how these uses relate to their properties. Brass: The two major metals in brass are copper and zinc. The proportion of the copper to zinc affects the colour of the alloy‚ ranging from a rose coloured alloy to a yellow alloy. The higher the proportion of zinc‚ the greater the hardness and tensile strength of the alloy. Brass can be highly polished and is lustrous

when the solute atoms take up positions of solvent atoms in the crystal lattice. If the two metal atoms are about the same size and have the same crystallographic structure‚ then the two metals may form a solid solution. Brass‚ an alloy composed of copper and zinc‚ is an example of a substitutional alloy. Alloys have different applications depending on their properties. The various types of steel and iron are all alloys classifiable by their content of other materials. For instance‚ wrought iron has

You can not manufacture the containers from glass due to possible breakage. Nor will plastic containers do because plastic tends to harden over time and also may shatter. This leaves metal. Unfortunately‚ many metals get eaten away (corrode)‚ when they come in contact with aqueous nitrates. Company documents indicate that copper‚ lead‚ zinc‚ and magnesium metals

The World Copper Factbook 2013 About ICSG The current members of ICSG are: Australia The International Copper Study Group (ICSG) was formally established as an autonomous inter-governmental organization on 23 January 1992‚ following a series of Ad Hoc meetings sponsored by the United Nations (UNCTAD) in 1986 and 1987 to review the world situation of copper and discuss the need for such a body. ICSG serves to increase copper market transparency and promote international discussions

Lab Chapter 4 4.1.1 Exercise: Standards are important for NIC‚ Connectors and Media‚ because of the Stability‚ Consistency‚ and Minimization of packet errors. 4.1.2 Exercise: Why is it so low when the capacity for transmission electricity on the copper wire is so high? Because‚ due to truncation on the transmission of voltage with an electric current. 4‚1‚3 Exercise: It’s used in the Healthcare facilities‚ because it’s more fire resistance. 4.1.4 Exercise: Category | Maximum Speed | Application

(measured in amperes) is what is meant by electric current. In most materials‚ the direct current is proportional to the voltage (as determined by Ohm’s law)‚ provided the temperature remains constant and the material remains in the same shape and state. Copper is the most common material used for electrical.Silver is the best conductor‚ but it is expensive. It has a resistivity of 1.6×10−8 Ω⋅m. Because gold does not corrode‚ it is used for high-quality surface-to-surface contacts. However‚ there are also

Electroplating shop: Electroplating is primarily used for depositing a layer of material to bestow a desired property to a surface that otherwise lacks that property. Mainly electroplating is used for the following purposes: * Abrasion * Wear resistance * Corrosion protection * lubricity and * Aesthetic qualities The electroplating shop of Energypac Engineering Limited consists of three sections. i) Seven color section ii) Nickel section iii) Silver section Seven color section:
