Scandinavian Black Metal Specific Purpose: To inform the audience about the origins and history of Black Metal in scandinavia. Introduction: A.Good morning everyone, I would like to start off by asking some questions. Does anyone here listen to Metal music regularly? Okay, and now, does anyone here listen to Black Metal music regularly? Alright, does anyone here have any idea of what Black Metal is? No? B.That is perfectly fine because that is what I’m going to talk to you guys about today
The Metal Controversy Over the past few decades, there has been a rapid increase of interest in the music genres of rap, hip hop, and pop. There are also, however, misconceptions of a particular genre, that many overlook; metal music. The most underrated types of metal bands (Black Metal, Deathcore, and Progressive bands) are categories that lead to the controversies surrounding this genre. When approaching a topic for my essay I wanted to find one that was unique, metal music in itself is something
I awoke in the forest. It was evening, the sun had long set. The smell of the woods surrounded me, almost suffocating me with the musk. I gazed before me as I stood, no lights, no way to see the path. I was lost, the thick trees blocking any light that might guide me. I began to walk slowly, watching each step carefully. The silence pressed against my ears, it was deafening. My eyes began to adjust to the pressing darkness with each step, and I noticed I was in a large clearing. Fear gripped me,
which makes the metal more reactive. I gathered together four different metals and acid compounds which all reacted with one of the elements in the past, for example, Iron Sulphate (FeSO4) contain iron. I prepared equipment I would use for the experiment, such as a pipette to carry the acid in, tweezers to lift the metals in, trays to pour the acids in, etc. I took an appropriate amount of acid and added in and the tray using the pipette. I then used the tweezers to pick up the metal with and add
2.3 Cogne grade 329HT Cogne grade 329HT (steel grade: 1.4462) is a type of duplex stainless steel. It contain higher content in molybdenum than other steel. The advantages of 1.4462 is high yield and tensile stress. It is able to endure corrosion and stress corrosion cracking. The cost is also higher than other as grade1.4436 and 1.4301. Due to its outstanding properties, it is always used in many construction and industrial aspects that location in seawater. For example, the offshore drilling
A metal is deemed “precious” because of its rare quality and high economic value. Precious metals are naturally occurring metallic elements characterized by their impressive resistance to both corrosion and oxidation. Precious metals known today include the coinage metals; gold and silver, and the platinum group metals; platinum, palladium, rhodium, iridium, ruthenium, and osmium. In general, precious metals are less reactive than most elements. They are also ductile and have a high luster. Some
When two dissimilar metals (e.g. Steel and Brass) are physically connected and exposed to an electrolyte, the metal higher in Electrochemical undergoes corrosion .This type of corrosion, is called “Bimetallic or Galvanic Corrosion.” Symptoms of Bimetallic Corrosions The first sign of galvanic corrosion is paint blistering (starting on sharp edges) below the water line—a white powdery substance forms on the exposed metal areas. As the corrosion continues, the exposed metal areas will become deeply
find a retort. Two people caught my attention in the room. They were a girl and a boy sharply dressed in pickle-green uniforms. Their chests were decorated with numerous shiny metals that reflected their accomplishments. The girl's dark brown hair was neatly tied in a bun off of her shoulders, and the boy's was shaven. Their black shoes were so shiny you could see your own reflection in them if you looked. They walked over to me and introduced themselves as Commanding Officer Cadet Lieutenant Colonel
When choosing a wedding band, you want to be sure that the metal will be durable, last for a very long time, and make you incredibly happy. While tungsten is a newer material to the wedding band market, it's one that can last a lifetime. As a symbol of your new marriage, you want a metal that will last. There are plenty of options for stylish rings, but we should talk about the Tungsten carbide wedding band pros and cons of choosing this material for your wedding ring. Pros 1. They're Less Expensive
Investigating the Thermal Decomposition Of Metal Carbonates Aim: To investigate a range of metal carbonates and see if they thermally decompose. Thermal Decomposition INVESTIGATION [IMAGE] ------- Written By Tauqir Sharif ------------------------ Research: When a metal is thermally decomposed the bond between the metal and its carbonate (carbon and oxygen) is removed and the carbonate is released as carbon dioxide. Metal Carbonate = Metal Oxide + Carbon Dioxide Malachite
rust on steel and other metals. A coating of tin also gives a great look to plain old steel. Tin cans for food prevents weak acids from damaging the inside of the can. Not many cans are made of tin since aluminum started to be used for cans tins use dropped sharply. Tin is also used to coat staples, pins, bronze bell, pewter pitchers and many others things. Another popular tin mixture is tin and lead. Tin and lead make solder for electric work. Battery contacts in the Black and Decker snake lights
The Rate of Reaction Of Metals with Acids Introduction In this investigation I will be looking at the rate of reaction between a metal, which will be magnesium ribbon, and an acid. The acids will either be hydrochloric, ethanoic, sulphuric or phosphoric acid. I will be finding out if the activation energy changes depending on whether a strong or weak acid is used. I will also be investigating whether or not there is a change in the order of reaction if a dibasic acid is used instead of a monobasic
Alchemy The science by aid of which the chemical philosophers of medieval times attempted to transmute the baser metals into gold or silver. There is considerable divergence of opinion as to the etymology of the word, but it would seem to be derived from the Arabic al=the, and kimya=chemistry, which in turn derives from the late Greek chemica=chemistry, from chumeia=a mingling, or cheein, 'to pour out' or 'mix', Aryan root ghu, to pour, whence the word 'gush'. Mr. A. Wallis Budge in his "Egyptian
table. Its atomic mass is 88.9059 and the complete electron configuration is 2-8-18-9-2. Although it is a transition metal, located in group 3 on the periodic table, it forms only one ion, with a +3 charge. Yttrium was discovered by Johan Gadolin in 1789 and is an iron gray color. In 1787, Carl Axel Arrhenius, who was an army lieutenant as well as a part-time chemist, found a heavy black rock near Ytterby, which is located in Sweden. He thought it had tungsten in it, and sent it to other chemists for
the waste product of copper ore smelting and refining process while spent copper slag is the waste product from the process of abrasive blasting of metal surfaces. It is widely used in ship building, ship repair, other steel fabrication industries, building and industrial fields. According to copper industry report in the year 2010, for every ton of metal production about 2.2 tonne of slag is generated. Improper disposal and dumping of copper slag will cause
Deville, in France, obtained the metal by reducing aluminum chloride with sodium. Aided by the financial backing of Napoleon III, Deville established a large-scale experimental plant and displayed pure aluminum at the Paris Exposition of 1855. Aluminum is a lightweight, silvery metal. The atomic weight of aluminum is 26.9815; the element melts at 660° C (1220° F), boils at 2467° C (4473° F), and has a specific gravity of 2.7. Aluminum is a strongly electropositive metal and extremely reactive. In contact
Ceramics - Incredible Refractory Materials Introduction First we will start with the definition of refractories and ceramics. Refractories and ceramics are non-metallic materials capable of maintaining physical and chemical stability at high temperatures. Refractories in modern practice are usually ceramic in nature, and are used in a wide variety of primary, secondary and tertiary industries. Wherever an industrial process involves heat in excess of 700 to 800 degrees Fahrenheit (roughly), one
its alloys is brazing. Many different types of pure metals and alloys of brazing filler materials are developed, they are available in a variety of forms, they are foil, paste, sheet, powder, wire, rod etc. This to reduce the difficulties of the process putting them between the base metals as various metals have different physical shapes and properties. The process requires a lot of attention and care in order to minimize the gaps in the metals that are being joined which could lead to failure of
precious metal. A symbol of wealth and prosperity, it has been a value for explorers and adventurers and a lure for conquerors. Today it is vital to commerce and finance; popular in ornamentation, and increasing importance in technology. The nature of gold is diverse. The chemical element gold is a heavy, soft metal. It weighs nearly twice as much as lead. Shiny and deep yellow in color, gold is one of two metals, which are not gray or white when pure. Gold is the most ductile of metals. Properties
Investigating Factors that Affect the Rate of Reaction Between a Metal and an Acid Factors that may affect the experiment + fair test The variables that could affect the rate of reaction are the temperature, amount of magnesium, concentration of acid, surface area of magnesium and volume of acid. The variable I am going to change is the concentration of acid. I am going to measure how long it takes a piece of magnesium(no more than 20m in length) to react in different concentrations of
