Zinc sulfide (or zinc sulphide) is an inorganic compound with the chemical formula of ZnS. This is the main form of zinc found in nature, where it mainly occurs as the mineral sphalerite.
The Zambia National Service (ZNS) plays a crucial role in various military operations, working in conjunction with other branches of the defence forces. Its functions and objectives are guided by four key pillars, serving as the foundation for its ongoing transformation.
Zinc compounds are chemical compounds containing the element zinc which is a member of the group 12 of the periodic table. The oxidation state of zinc in most compounds is the group oxidation state of +2. Zinc may be classified as a post-transition main group element with zinc (II).

Zinc sulfate is produced by treating virtually any zinc-containing material (metal, minerals, oxides) with sulfuric acid. [4] Specific reactions include the reaction of the metal with aqueous sulfuric acid : Zn + H2SO4 + 7 H2O → ZnSO4·7H2O + H2. Pharmaceutical-grade zinc sulfate is produced by treating high-purity zinc oxide with sulfuric acid:
Sphalerite is a sulfide mineral with the chemical formula ( Zn, Fe) S. [5] It is the most important ore of zinc. Sphalerite is found in a variety of deposit types, but it is primarily in sedimentary exhalative, Mississippi-Valley type, and volcanogenic massive sulfide deposits.
Zinc cadmium sulfide is a mixture of zinc sulfide (ZnS) and cadmium sulfide (CdS). It is used for its fluorescent properties. Bioaccumulation of this chemical may occur along the food chain, for example in plants and in seafood.
Zinc is a chemical element; it has symbol Zn and atomic number 30. It is a soft, but slightly brittle metal at room temperature and has a shiny-greyish appearance when oxidation is removed. It is the first element in group 12 (IIB) of the periodic table.
Zinc nitride ( Zn 3 N 2) is an inorganic compound of zinc and nitrogen, usually obtained as (blue)grey crystals. It is a semiconductor. In pure form, it has the anti- bixbyite structure.
Diethylzinc (C 2 H 5) 2 Zn, or DEZ, is a highly pyrophoric and reactive organozinc compound consisting of a zinc center bound to two ethyl groups. This colourless liquid is an important reagent in organic chemistry. It is available commercially as a solution in hexanes, heptane, or toluene, or as a pure liquid.
