QuestionWhat is the name of the compound ?
Studdy Solution
STEP 1
Assumptions1. The compound is . . We are using the IUPAC naming convention for inorganic compounds.
STEP 2
The given compound is a binary compound, which means it is composed of two different elements. The first element is Cobalt (Co) and the second element is Oxygen ().
STEP 3
The subscript '2' after Cobalt (Co) in the formula indicates that there are two atoms of Cobalt in the compound.
STEP 4
The subscript '3' after Oxygen () in the formula indicates that there are three atoms of Oxygen in the compound.
STEP 5
In the IUPAC naming convention, the first element in the compound is named first, and the full element name is used. So, the first part of the name is 'Cobalt'.
STEP 6
The second element in the compound is named as if it were an anion. So, Oxygen becomes 'oxide'.
STEP 7
The prefixes 'di-', 'tri-', etc., are used to denote the number of atoms of each element in the compound. However, for transition metals like Cobalt, the oxidation state is used instead of prefixes. The oxidation state is equal to the charge that the atom would have if all bonds wereionic, and is indicated in roman numerals in parentheses.
STEP 8
In this compound, Cobalt has an oxidation state of +3 (since it is bonded with three Oxygens, each with a -2 charge). So, the name of the compound is 'Cobalt (III)'.
STEP 9
Putting it all together, the name of the compound is 'Cobalt (III) oxide'.
The name of the compound is 'Cobalt (III) oxide'.
