What is the chemical Formula for Cobalt iii oxide?
Co2(CO3)3The chemical formula of cobalt(III) carbonate [not cobalt(111)] is Co2(CO3)3.
What is the chemical name of cobalt oxide using the stock system?
Cobalt oxides are: cobalt(I) oxide, cobalt(II) oxide and cobalt(II,III) oxide.
What is cobalt iii oxide?
Cobalt(III) oxide is a chemical compound with the formula Co2O3. It is a dark brown solid that is insoluble in water. It is used as a catalyst in chemical reactions and as a pigment in ceramics.
What does the roman number III indicate in cobalt III oxide indicate?
The roman number III indicates that the ion of cobalt present in this form of cobalt in the cobalt oxide is Co3+. Since cobalt also exists as a Co2+ form, these must be distinguished in some way. The standard is to use roman numerals to denote the charge. Both Cobalt (III) oxide and Cobalt (II) oxide still have the chemical formula of Co3O4.
How many atoms of cobalt are present in a 56.7 mg sample of rock that contains 56.7 percent of cobaltic oxide?
Assuming that cobaltic oxide is the only cobalt-containing constituent of the rock, the mass of cobaltic oxide in the rock is 56.7(0.567) or 32.149 mg. The formula of cobaltic oxide is Co2O3 and its gram formula mass is 165.86. The formula shows that each formula unit contains 2 atoms of cobalt. The amount of 32.149 mg corresponds to (32.149 X 10-3)/165.86 or 1.938 X 10-4 formul units of cobaltic oxide. The number of atoms in this mass is therefore Avogadro's Number X 2 X 1.9438 X 10-4 or 2.34 X 1020 atoms of cobalt, to the justified number of significant digits.
Cobalt II Oxide formula?
The formula for cobalt II oxide is CoO. It contains one cobalt ion with a +2 charge and one oxide ion with a -2 charge, resulting in a neutral compound.
What is the chemical Formula for Cobalt iii oxide?
Co2(CO3)3The chemical formula of cobalt(III) carbonate [not cobalt(111)] is Co2(CO3)3.
What is the formula for cobalt(III) oxide?
Co2O3
