Iron ore

Task-5 a) • Metals Metal structure is made up of crystals of metals which are made up of positive metal ions and these ions are surrounded by a sea of delocalized electrons. To separate these substances from this crystal lattice a lot of energy is needed. In between the positive and negative ions is present a strong electrostatic force of attraction. That is the reason why metals have strong melting and boiling points. In order to slide one layer of the metal ions over the other layer very less…

In this experiment, I tested the effect of saltwater on the formation of rust on an iron nail. To test this, The first step was to fill each labeled cup with the correct ratio of salt to water. The ratios varied between groups which created different concentrations of salt for the different groups thereby constructing different levels of my independent variable. The next step was to record the initial mass of each nail and then place them in the cups. Then, the nails were left to soak in their…

Iron is an essential mineral that is needed for oxygen transport in the body’s blood and muscles. It is a major component in making hemoglobin in red blood cells and myoglobin in muscles. Hemoglobin and myoglobin are two proteins that transport oxygen from the lungs to the body’s muscles via blood. Iron also plays a role in energy metabolism. During exercise, iron aids the body by converting carbohydrates into energy and supplying the muscles with fresh oxygen. There are two forms of iron, heme…

“From the dawn of mankind, metals have fascinated man in many ways. From simple items found in the fire to advances in forming metals into trinkets, jewels, to weapons.” (A History of Welding). Welding is a profession that has been around since the dawn of the use of metals. The art of welding has changed the way we make things, and how we are able to build massive structures that stand taller than mountains. Well, this art form is called welding, and I believe it would suit me very well as a…

Iron is popularly known for its role in helping the body make hemoglobin, where it facilitates the active transport of oxygen throughout the body. However, the function of this micro nutrient is not limited to its function in the red blood cell; it is also an important part of different enzymes as well and initiates various essential biological processes in our body. Iron plays an important role in changing blood sugar into a form of energy for the body. Iron aids in immune system health and…

One of the challenges chemical engineers face with ethane cracking in a tubular reactor is the formation of a detrimental coke layer on the inner tube wall. According to the article [1], the mechanism is mainly induced by degradation of hydrocarbons to an aromatic structure by condensation and dehydrogenation. This brings about a bunch of various effects described in the article. In my model built during the term project, I decided to introduce a new effect of reducing the diameter, consider…

know what you will need to get started. You will need shampoo, a rubber band or a hair clip, a plastic bag or a hairdryer, a heat protectant conditioner, a silk scarf, a wide tooth comb, a blow dryer (optional), a light grease (optional), and flat irons. The conditioner does not have to be heat protected but you run the risk of causing split ends or burning your hair. Now that you have all the materials you will need you can start the process to straightening your hair. The first thing you need…

rust is seen every day and affects one 's life every day. This is due to the fact that “Iron doesn’t hold onto its electrons very tightly, says Scully, making it the perfect anode for an electrochemical reaction to take place” (Brownlee 2). Skully is a corrosion expert at the university of Virginia (Brownlee 1-2). When metal rusts, the metal atoms lose their electrons to oxygen, which forms a bond between the iron and oxygen creating the compound that is seen in the form of rust (Brownlee…

Metal plays a key role in development and it is the backbone for the manufacturing industry. For years, various metal have been extracted from the mineral ore found in nature, but with the time high grade ore have is getting depleted and the option at left with us is to processing low grade ore which makes recovery process expensive. In such scenario recycling metals seems a lucrative option as it helps environment by reducing the amount of scrap or waste material getting disposed into…

Notes from You-tube Plantopia Videos In this paper I will write some points about the videos I watched. The first video about The Carbon Cycle, I learned from this video the Carbon is the basic building block of life, and there are these atoms are unique in every place on earth. Carbons forms the flora and fauna the earth, and are also stored in the ocean and the atmosphere, and the planet 's crust. Carbon atom can spend millions of years moving through the ground in a complex cycle. This…
