Corrosion of Iron - Flinn Sci

When iron metal is exposed to oxygen and water, a familiar result is observed—rust. The rusting process consists of sev-eral steps. In the first step, iron is oxidized to iron(II) ions, Fe2+, and oxygen from the air is reduced to hydroxide ions, OH–. This oxidation–reduction reaction takes place via two separate half-reactions (Equations ...

Impurity: Pure iron tends to rust more slowly when compared to iron containing a mixture of metals. The size of the iron object can also affect the speed of the rusting process. For example, a large iron object is likely to have small deficiencies as a result of the smelting process.

These diagrams demonstrate two operating conditions which influence the x-ray production process. Please note that the number of electrons that are released will directly influence the number of x-rays that are generated and therefore the dose of radiation also. While these diagrams show just a few electrons, the reality is that


The process of photosynthesis involves the absorption of CO 2 by plants to produce carbohydrates. The equation is as follows: CO 2 + H 2 O + energy → → (CH 2 O) n +O 2. Carbon compounds are passed along the food chain from the producers to consumers. The majority of the carbon exists in the body in the form of carbon dioxide through ...


As with all large-scale manufacturing processes, the production or iron and steel generates by-products. On average the production of 1 tonne of steel results in 200 kg (EAF) to 400 kg (BF/BOF) of by-products. The main by-products produced during iron and crude steel production are slags (90%), dusts and sludges.

Iron from the blast furnace contains about ~96% iron with ~4% of impurities including carbon, silica and phosphorus. In this state the cast iron is too hard and too brittle for most purposes. Cast iron is hard and can be used directly for some purposes eg manhole covers, ornamental railings because of its strength in compression and is very ...


Biochemistry and physiology. In contrast to zinc, iron is an abundant element on earth[2,9] and is a biologically essential component of every living organism.[10,11] However, despite its geologic abundance, iron is often a growth limiting factor in the environment.[] This apparent paradox is due to the fact that in contact with oxygen iron forms oxides, which are highly insoluble, and …

Steel - Wikipedia

Steel is an alloy made up of iron with typically a few tenths of a percent of carbon to improve its strength and fracture resistance compared to other forms of iron. Many other elements may be present or added. Stainless steels that are corrosion- and oxidation-resistant need typically an additional 11% chromium.Because of its high tensile strength and low cost, steel is used in …
