Copper + Oxygen ( Copper Oxide Cu (I) + O ( CuO Rust is very similar to corrosion but only occurs in iron and steel (an iron alloy). Rust is formally known as oxidation‚ which occurs when Oxygen (O) comes into contact with iron (Fe). Overtime‚ the oxygen reacts and combines chemically with the iron‚ forming a substance named Iron Oxide (Fe2O3)‚ which weakens the physical bond of the iron.[2] Chemical Equation of Rust: 4Fe + 3O2 --> Fe2O3[3] To maximize rust‚ a certain level of moisture is

The Geritol Solution What is the basis for Martin’s premise that seeding the ocean with iron would help combat global warming? The idea of stimulating plankton growth with iron grew out of the fertile mind of the late John H. Martin‚ an oceanographer at Moss Landing. Martin sought originally to explain a long-standing mystery concerning barren waters in the Antarctic‚ subarctic‚ and equatorial Pacific Oceans. With the abundant concentrations of nutritious nitrate and phosphorus in

the crystal structures of iron. Substitutional alloyIt is formed when the solute atoms take up positions of solvent atoms in the crystal lattice. If the two metal atoms are about the same size and have the same crystallographic structure‚ then the two metals may form a solid solution. Brass‚ an alloy composed of copper and zinc‚ is an example of a substitutional alloy. Alloys have different applications depending on their properties. The various types of steel and iron are all alloys classifiable
