3. Cycle the image is on the model
The sulfur cycle is the collection of processes by which sulfur moves to and from
minerals (including the waterways) and living systems. Such biogeochemical
cycles are important in geology because they affect many minerals. Biochemical
cycles are also important for life because sulfur is an essential element, being a
constituent of many proteins and cofactors.[1]
steps of the sulfur cycle are:
Mineralization of organic sulfur into inorganic forms, such as hydrogen
sulfide (H2S), elemental sulfur, as well as sulfide minerals.
Oxidation of hydrogen sulfide, sulfide, and elemental sulfur (S) to sulfate (SO4
2−).
Reduction of sulfate to sulfide.
Incorporation of sulfide into organic compounds (including metal-containing
derivatives)
4. DESCRIPTION and uses of the sulphur
Sulphur is also used in batteries,detergentes,fungicides,manufacture or
fertilizer,gun power,matches and Fireworks.Other applictions are making
corrosion-resistant concrete wich has great strength and is forst resistant, for
solvents and in a host of other products of the chemical and pharmaceutical
industries
5. Importance of the sulphure
Life on earth may have been posible because sulpure.Conditions in the early
seas were such that simple chemical reactions could have generate the range
of aminoacids that are the building blocks of life
