The direct reaction between iron metal and iodine can be used to prepare iron (II) iodide, FeI 2. Fe(s) + I 2 (s) → FeI 2 (s) (grey) Reaction of iron with acids. Iron metal dissolves readily in dilute sulphuric acid in the absence of oxygen to form solutions containing the …
How Aluminum is Produced rocksandmineralsm
The immense amounts of power required to produce aluminum is the reason why aluminum plants are almost always located in areas where affordable electrical power is readily available. Some experts maintain that one percent of all the energy used in the United States is used in the making of aluminum.
Lanthanum Element information, properties and uses
A horizontal row in the periodic table. The atomic number of each element increases by one, reading from left to right. Block Elements are organised into blocks by the orbital type in which the outer electrons are found. These blocks are named for the characteristic spectra they produce: sharp (s), principal (p), diffuse (d), and fundamental (f).
Krypton | Encyclopediam
Krypton is only one of many valuable elements produced by the fractional distillation of liquid air. More than threequarters of air is made up of nitrogen. Nitrogen is used to produce a wide variety of chemical compounds, particularly ammonia. Because it is much less reactive than oxygen, nitrogen is used to protect many substances from oxidation.
