I. Abstract This paper will provide a detailed discussion about iron metal. The chemical, physical and mechanical properties of iron metal will be discussed. Additionally, the occurrence and major applications of the metal will also be provided. This is intended to provide an understanding of the iron metal and the chemistry around it. The geometry of coordination together with the different oxidation states will be included in the discussion. It should be noted that iron is one of the few metals that is considered to have wide range of applications. There are many devices, accessories and equipment that are made out of iron metal. Its abundance on earth is also something that is considered to be of great importance. Just like other metals, iron is extracted from the earth’s crust through mining process. Iron is extracted from the earth in form of iron ore. …show more content…
As such, the metal is known to have capability of being drawn into thin wires. Additionally, iron can be hammered into tiny sheets. The tensile strength of iron are considered to be very high. Iron can be stretched to a great extent without breaking. in addition to that, iron has the ability to bend, hammer, roll, shape, form and cut (Romney, Thacker & Leibold, 2007). Chemical properties of iron constitute the manner in which it reacts with other chemical compounds. As a matter of fact, iron is known to be a very active element. Iron is known to combine with oxygen in moist environment to form rust. The product of the combination of iron and oxygen is iron oxide (Fe 2 O 3 ). Iron dissolves in acids and reacts to form a salt and water. There are also many other elements that iron is known to react with. Iron reacts with hot water and steam to produce rust and hydrogen gas (Romney, Thacker & Leibold, 2007). III.
Iron is naturally iron oxide and purified iron rapidly returns to a similar state when exposed to air and water. This whole process can be seen below in figure 3 – ‘The corrosion
Iron is a trace element, which is a group of minerals present in small quantities in the body. Other trace elements include copper, zinc, selenium, manganese and iodine. These minerals cannot be synthesized by the body and must therefore be supplied in the diet. Iron is the most common trace element in the human body; adult males have approximately 3.5 g iron in total, or 50 mg per kg body weight while females have about 2g total iron or 35 mg per kg bodyweight. Iron can exist in oxidation states from -2 to +6, but mainly exists in the ferrous (+2) and ferric (+3) states in biological systems. As iron has the ability to accept and donate electrons readily, it can interconvert between these two forms with ease. Thus, iron can participate in
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 with air, aluminum rapidly becomes covered with a tough, transparent layer of aluminum oxide that resists further corrosive action. For this reason, materials made of aluminum do not tarnish or rust. The metal reduces many other metallic compounds to their base metals. For example, when thermite (a mixture of powdered iron oxide and aluminum) is heated, the aluminum rapidly removes the oxygen from the iron; the heat of the reaction is sufficient to melt the iron. This phenomenon is used in the thermite process for welding iron .
Many elements, like lead, are very important to the structure and formation of many of the products we use. Throughout history, lead has been developed, mined, extracted, and used. Lead, since its finding thousands of years ago, has proven to be a tricky element with many diverse health effects. Scientists have developed products, and processes that still continue to used lead. Lead is an extremely important and influential element in our daily lives.
Iron is called a trace mineral, but its effects are mighty. We need it to produce hemoglobin, the oxygen carrier in red blood cells that brings oxygen to the rest of the body. Iron is also needed to produce myoglobin, the oxygen reservoir in the muscle cells.
Pounding metal and fabricating metal in thin sheets and sections that humans need or want has a long history. The discovery of how to make and control fire made extracting metals form or more efficient instead of having to find almost pure nuggets of metal. In many civilizations copper was the metal they used but that was succeeded by bronze eventually it is made of copper and tin.
Ironclad is a 2011 film that is an exciting undertaking with memorable scenes all around the film. It was basically English and Erick Kastel that put the entire story line of the film into writing and it was then Jonathan English who directed the film. Jonathan’s work is well reflected in the entire film where it conveys the story line to the best order. At the beginning of the film we are introduced to a description of the wealthy businessmen of England who then rebelled against King John, Paul Giamatti in real situation. They had the support of the Knights and this even gave them morale and encouraged them in their rebellion that prompted King John to sing the ‘Magna Charta’ which was an agreement laid down in form of a document to push for equality of all freemen in England and it also aimed at reducing the powers of the monarch.

Pure iron has a hardness that ranges from 4 to 5. It is soft and ductile. Iron can be easily magnetized at ordinary temperatures and at 790°C the magnetic property disappears. Pure iron melts at about 1535°C, boils at 2750°C, and has a specific gravity of 7.86. Chemically, iron is an active metal. When exposed to humid air, iron forms a reddish-brown, flaky, decay known as rust.
The inefficiencies and the problems involved in making steels in the traditional form of ingots are alleviated by the continuous-casting process, which produces higher quality steels at reduced costs. Conceived in the 1860s, continuous or strand casting was first developed for casting nonferrous metal strips. The process now is used widely for steel production, with major productivity improvements and cost reductions.
This book was given to me by a good friend who knew that I had an interest in Asia. I chose to read it because it was a true story and was told that it was a good read.
By adding up to 2%,of carbon it makes the steel tough and strong. Although it’s tough and strong, it is able to bend. To make sure that the metal doesn’t rust, it has a zinc coating on it. Iron is 26 on the periodic table,and considered an “transition metal,” meaning that it is ductile and malleable, and conduct electricity and heat. ... “Some other elements that are similar to iron are cobalt and nickel. They are the only elements known to produce a magnetic field.” Zinc is 30 on the periodic table and it is also a transition metal like iron. “The first iron used by humans is likely to have come from meteorites.” A meteorite is a meteor that survives its passage through the earth's atmosphere such that part of it strikes the ground. More than 90 percent of meteorites are of rock, while the remainder consist wholly or partly of iron and nickel. Meteors are believed to have been from the asteroid belt of Mars and
Extractive metallurgy is the practice of removing metals from their ores or from the naturally occurring aggregates of minerals and refining the extracted raw metals into a purer form. The art of extracting metals from their ores dates back thousands of years3 with gold and copper being the first metals used by man. Although the techniques for the recovery of metals have developed steadily over the years, there is an ever increasing need for the further development of new and innovative techniques. This can largely be attributed to the rapidly increasing demand for metals in all aspects of the modern world, the decreasing supply of high-grade ores and the need for recycling. Separation is the essence of metal extraction
Rust is a coating of iron oxide that is formed by oxidation on an iron alloy. When a person sees rusting, it is a form of corrosion. Rust is found more often when there is lots of moisture around the iron or iron alloy. Iron oxide is formed when the iron alloy is mixed with oxygen. According to howstuffworks.com, ‘when a drop of water hits an iron object, two things begin to happen almost immediately. First, the water, a good electrolyte, combines with carbon dioxide in the air to form a weak carbonic acid, an even better electrolyte. As the acid is formed and the iron dissolved, some of the water will begin to break down into its component pieces -- hydrogen and oxygen. The free oxygen and dissolved iron bond into iron oxide, in the process
