Concept explainers
(a)
Interpretation:
The systematic name of
Concept introduction:
The chemical formula is used to indicate the structure of a chemical substance. The formula contains the element with the number of the atoms denoted as subscripts. The naming is done by using the method of the IUPAC system that has certain rules to be followed.
(b)
Interpretation:
The systematic name of
Concept introduction:
The compounds are indicated by using chemical structures, that are denoted by using the element with the
(c)
Interpretation:
The systematic name of
Concept introduction:
Compounds are named by using the chemical formula and the naming of the compound is by using the IUPAC method. The elements are denoted by using the elemental formula and the number of atoms is indicated as subscripts. They are brackets and parentheses to indicate the repetition of molecules.
(d)
Interpretation:
The systematic name of
Concept introduction:
The chemical structure denotes chemical compounds wherein the elements denote each atom. The number of atoms is denoted as subscripts. The atoms are denoted within brackets and parentheses. Roman numerals are used to indicate the oxidation state.

Why does the reaction not occur as: 4Ag(s) + 8CN−(aq) ⟶ 4[Ag(CN)2−(aq)?arrow_forward
- The photographs below (a) show what occurs when a solution of iron(III) nitrate istreated with a few drops of aqueous potassium thiocyanate. The nearly colorlessiron(III) ion is converted to a red [Fe(H2O)5SCN)2+ion. (This is a classic test for thepresence of iron(III) ions in solution.)[Fe(H2O)6]3+(aq) + SCN−(aq) ⇄ [Fe(H2O)5SCN]2+(aq) + H2O(ℓ)(a) As more KSCN is added to the solution, the color becomes even more red.Explain this observation.(b) Silver ions form a white precipitate with SCN−ions.
