the substance. Oxidation: Also known commonly as rusting‚ this process combines oxygen molecules with the mineral ions such as iron‚ calcium or magnesium. Oxygen is normally taken from the moisture in soil or air. Subsequently‚ it results in reduction of the mineral to a less stable compound. A typical example is conversion of iron (Fe) radicals into rust or iron oxide (Fe2O3) which is weaker. Reference:

from. Bangladesh has a lot of floodplains and it is very hot. For my house roof the first layer on the frame would be 15mm of triplex nailed on to the frame of the house. The design will have corrugated galvanised iron on the frame. If the water went through the corrugated galvanised iron‚ it is able to slide the water down outside. There will be big pipes on the end bottom of the roof bringing the water beside the house and using it to take showers and etc. As the floor of the attic‚ I will put a

Blast Furnace Hot Metal is one of the most critical problems in today’s Iron Making. With deterioration in quality of iron ore day by day‚ silica load in the burden material has a steady increase. The same story is with the Coke ash‚ which passes good amount of silicon in the hot metal. Every 0.1% reduction in silicon in the hot metal gives rise to 1.5 % increase in hot metal production. In the competitive scenario of today’s Iron Making hence it is necessary to reduce every bit of Silicon in hot metal

Manganese would be a solid. It would be classified as a metal. The color would be silver/grey. When armies were at war their helmet was made out of steel and 12% Manganese. In 1942 nickels were made out of 9% Manganese. Manganese can rust in water like iron. Manganese is also an important part of our body. Manganese can help our bodies in many ways and ruin our bodies to. Scientist shows that without Manganese we wouldn’t be able to heal from surgery faster‚ helps from bone loss‚ and is an antioxidant

Hypothesis: I think that the chemical change is an irreversible process. The wet iron filings by the next day it will turn into rusting material because it is exposed to the atmosphere. While the dry iron filings is not III Materials: The setup in the previous activity‚ small plate‚ dry iron filings. IV Procedure: 1. Place the iron filings on a dry plate. 2. Compare the physical properties of the dry and wet iron filings. 3. Take note of the differences in their physical properties if any.

Port Kembla Steelworks has spent $18 million on upgraded sinter machines that reduce the amount of coke need for the sintering process. The sintering process being getting the small particle of iron that were too small to go through processing and putting them through 1100-1300oC heat they will coalesce and form larger particles which improves resource efficiency. The upgrade involve using natural gas rather than coke to generate the heat in the

Iron Man: The Real Hero In today’s society‚ the concern of people and laws are not about doing good but rather having the appearance of good. People no longer care about what they need to stand for‚ only that they look like they aren’t sitting down. In fact‚ men today are treated as outcasts when sticking up for a good thing when it doesn’t have a pleasant appearance. Men such as Thomas Jefferson‚ Leonidas‚ Joshua and Jesus‚ men that represent something greater than what meets the eye‚ are scarce

Hypothesis: Rust is a reddish or yellowish-brown flaky coating of iron oxide that is formed on iron or steel by oxidation‚ especially in the presence of moisture. The rusting process is electrochemical‚ meaning it forms from a chemical reaction which takes place in a solution where there is an electron transfer between the electrode and the electrolyte or species in solution. In the case of rusting‚ the transfer of electrons from iron to oxygen begins the electrochemical process. Electrolytes accelerate
