Mass copper oxide = 1.76 g Mass copper = 1.43 g So mass oxygen = 0.33 g. Number moles Cu = 1.43/63.5 = 0.02251 Number moles O = 0.33/16 = 0.020625. Lv 4. Copper(III) oxide Chemical compound. Relevance. 3 Answers. The chlorine-containing complex is formed if copper(I) oxide is dissolved in concentrated hydrochloric acid. The chemical formula for Copper (I) Oxide is determined using the rules for nomenclature for compounds made from metals and nonmetals. The ratio should be close to 1:1 as the formula of copper oxide is CuO. Copper(II) oxide, a black solid, and colourless dilute sulfuric acid react to produce copper(II) sulfate, giving a characteristic blue colour to the solution. No it is Cu2S3. Sulfide is a 2- ion. Forming copper(I) complexes (other than the one with water as a ligand) also stabalises the copper(I) oxidation state. Jack L. 1 decade ago. Favorite Answer.

Copper(III) oxides are constituents of cuprate superconductors. Source(s): https://owly.im/a73fD. 1 Cu: 1 O. Copper(I) complexes. Login to reply the answers Post; stgelais.
Copper 3 Sulfide. Divide by the smallest to give the ratio approx. Copper(III) oxide Categories This reference contains the names of substances and descriptions of the chemical formulas (including the structural formula and the skeletal formula). Desc: Copper(III) oxide is a hypothetical inorganic compound with the formula Cu₂O₃.It has not been isolated as a pure solid. Because copper is a transition metal, it can form ions with different charges (usually either +1 or +2). What is the formula for Copper(III) Sulfide? This would suggest a formula of CuO, which is the correct formula. 4 years ago. From this solution, blue copper(II) sulfate pentahydrate crystals may be obtained if desired. Copper(I)) oxide Cu2O Copper(II) oxide CuO Copper(III) oxide Cu2O3 Copper peroxide CuO2 There are also several copper(II) superoxide complexes, e.g. Cheviot ewes (mean live weight 50 kg) were given single doses of 0, 2.5, 5, 10, or 20 g cupric oxide particles in gelatin capsules while receiving a diet of marginal copper content based on pelleted oats. Lesson organisation. For example, both [Cu(NH 3) 2] + and [CuCl 2]-are copper(I) complexes which don't disproportionate.

This is a well-tried standard class experiment. 1 decade ago. Answer Save. Copper (III) is a 3+ ion . Example calculation. 0 0 0. Login to reply the answers Post; Angee A . is it Cu3S? There are several copper oxides.
