That is, in grams, the atomic weight of the element divided by the usual valence. [2] For example, the equivalent weight of oxygen is 16.0/2 = 8.0 grams. For acid–base reactions, the equivalent weight of an acid or base is the mass which supplies or reacts with one mole of hydrogen cations (H +).
2, Zn 3 P 2, Zn 3 As 2 and Zn 3 Sb 2), [65] [66] the peroxide (ZnO 2), the hydride (ZnH 2), and the carbide (ZnC 2) are also known. [67] Of the four halides, ZnF 2 has the most ionic character, while the others (ZnCl 2, ZnBr 2, and ZnI 2) have relatively low melting points and are considered to have more covalent character.

Zinc acetate is a salt with the formula Zn(CH 3 CO 2) 2, which commonly occurs as the dihydrate Zn(CH 3 CO 2) 2 ·2H 2 O. Both the hydrate and the anhydrous forms are colorless solids that are used as dietary supplements. When used as a food additive, it has the E number E650.
[2] The name zamak is an acronym of the German names for the metals of which the alloys are composed: Zink (zinc), Aluminium , Magnesium and Kupfer (copper). [ 2 ] The New Jersey Zinc Company developed zamak alloys in 1929.

Zinc gluconate dietary supplements. Zinc gluconate is the zinc salt of gluconic acid.It is an ionic compound consisting of two anions of gluconate for each zinc(II) cation.Zinc gluconate is a popular form for the delivery of zinc as a dietary supplement providing 14.35% elemental zinc by weight.
An equivalent (symbol: officially equiv; [1] unofficially but often Eq [2]) is the amount of a substance that reacts with (or is equivalent to) an arbitrary amount (typically one mole) of another substance in a given chemical reaction. It is an archaic quantity that was used in chemistry and the biological sciences (see Equivalent weight § In ...
