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.
Zinc acetylacetonate is an acetylacetonate complex of zinc, with the chemical formula of Zn (C5H7O2)2. The compound is in fact a trimer, Zn 3 (acac) 6, in which each Zn ion is coordinated by five oxygen atoms in a distorted trigonal bipyramidal structure. [5]
Metal acetylacetonates are coordination complexes derived from the acetylacetonate anion (CH. 3COCHCOCH−. 3) and metal ions, usually transition metals. The bidentate ligand acetylacetonate is often abbreviated acac. Typically both oxygen atoms bind to the metal to form a six-membered chelate ring. The simplest complexes have the formula M ...
The molar mass of atoms of an element is given by the relative atomic mass of the element multiplied by the molar mass constant, M u ≈ 1 × 10 −3 kg/mol = 1 g/mol. For normal samples from earth with typical isotope composition, the atomic weight can be approximated by the standard atomic weight [2] or the conventional atomic weight.
Zinc bromide (Zn Br 2) is an inorganic compound with the chemical formula Zn Br 2. It is a colourless salt that shares many properties with zinc chloride (ZnCl 2), namely a high solubility in water forming acidic solutions, and good solubility in organic solvents. It is hygroscopic and forms a dihydrate ZnBr 2 ·2H 2 O. [2]
Zn (18.45%), and 70 Zn (0.61%). [44] Several dozen radioisotopes have been characterized. 65 Zn, which has a half-life of 243.66 days, is the least active radioisotope, followed by 72 Zn with a half-life of 46.5 hours. [43] Zinc has 10 nuclear isomers, of which 69m Zn has the longest half-life, 13.76 h. [43] The superscript m indicates a ...
Acetylacetone is an organic compound with the chemical formula CH3−C (=O)−CH2−C (=O)−CH3. It is classified as a 1,3- diketone. It exists in equilibrium with a tautomer CH3−C (=O)−CH=C (−OH)−CH3. The mixture is a colorless liquid. These tautomers interconvert so rapidly under most conditions that they are treated as a single ...
The equivalent weight of an element is the mass which combines with or displaces 1.008 gram of hydrogen or 8.0 grams of oxygen or 35.5 grams of chlorine. The equivalent weight of an element is the mass of a mole of the element divided by the element's usual valence. That is, in grams, the atomic weight of the element divided by the usual ...
