Metals Essay Examples

Objects having magnetic field is called as magnets. Normally magnets are of two types- Permanent magnets and Electro magnets. Permanent magnets are those magnets which occur in nature and do not depend upon external source for their magnetic field. On the other hand electromagnets are those magnets which use electric current to generate magnetic field. […]

Diamond-coated Tungsten Carbide tools have demonstrated improved machining characteristics over coated tool steels commonly used today.With the increased use of composites, ceramics, and other ultra-hard / lightweight materials in numerous industries, diamond-coated machine tools are becoming more common since their performance improvements generally out weigh their increased cost. This paper is an empirical summary of […]

In the periodic table, 80% of the elements are metals. Of the metals, aluminum is the most abundant in the earth’s crust. Aluminum is concentrated in the outer 10 miles (16 km) of the Earth’s crust, of which it constitutes about 8% by weight; it is exceeded in amount only by oxygen and silicon. 1 […]

Ferrocene was acetylated in acetic anhydride and phosphoric acid. It proceeded via a Friedel-Crafts reaction without the use of organic solvents or strong Lewis acid. Operations and Observations A mixture of ferrocene (1. 5 g, 0. 008 mol), acetic anhydride (5 mL) and phosphoric acid (1 mL 85%) was heated over a steam bath until […]

The rates of reaction of Alkali metals and Alkaline Earth meatals are compared in this lab. The pH of each of the ensuing metal solutions are tested and the merchandises of the reaction between Ca and H2O is discovered. The tried elements are sodium. Li. K and Ca and each of them were placed in […]

In the geosphere, the content of aluminum is substantial and varies between 7.5% to 8.1% among metallic elements. Deviation from its intended trajectory is rare as the element has a strong attraction to oxygen owing to its high reactivity, leading to a powerful connection with O. This makes separation challenging. Hence, it must undergo the […]

Planning: * There are many ways in which to find out what ions are contained in different compounds. When substance is mixed to make solution, precipitation reactions and reactions with gas specifically are very useful to help us out with identifying which ions are contains in the substances. This test is for negative ions. * […]

Hi. I am Gold. I have been around since the beginning of time, but humans started to use me only 4000 years ago. Now, don’t think that you can throw me out into the garbage; there are millions of people who will come looking for me. Firstly, I am one of the most expensive and […]

In the preparation of alum from scrap aluminium experiment various techniques and apparatus was used to obtain pure alum crystals. During the procedure various potential hazardous chemicals was used and care had to be taken at all times when handling it. Protective clothing and eyewear had to be worn during the whole experiment. Initially a […]

The experiment was repeated in order to increase precision. Variables: Controlled: quantity of Magnesium and Taffies used, the volume of cold water used Manipulated: Magnesium, Taffies (metals used) Responding: Products formed due to reaction with each metal with cold water Data to be collected: Table showing the products formed and inference due to the reaction […]

Ductile and malleable are terms used to describe different properties of materials. Ductile means that a material can be easily formed into thin wires, while malleable means that it can be easily hammered into thin sheets. For example, a 20-gram piece of gold can be hammered into a sheet that will cover more than 6 […]

People are born with the insatiable desire to find somebody perfect. We spend our whole lives ransacking the world for the immaculate human being who deserves our boundless reverence and whom we should emulate. We are on an unceasing quest to find our own paragon of virtue. But what a treacherous thing it is to […]

The earliest operation of mining of bog iron in Maine began in Newfield but was a small scale operation but it continued for a long period of time. During the mid 1880’s the other enterprises were near Lubac, that was a lead mine and Katahdin Iron Works. There was a mining boom from 1879 to […]

Engineers and scientists use scientific knowledge to design and build machines that make our lives easier. The machines they build today started off with the basics, which are known as Simple Machines. Simple Machines are defined as the simplest mechanisms that use mechanical advantage to multiply force. These machines have either few or no moving […]

There had been an iron industry in Britain for about 2,000 years. It was on a small scale and located near the source of fuel i.e. charcoal, made mainly from oak trees. The main centres of production were the “Weald” in Sussex, the Forest of Dean and the “Wrekin” in Shropshire. During the 18th Century […]
