(a)
Interpretation:
The chemical formula for the oxide in the highest oxidation states of each of the given elements is to be determined.
Concept introduction:
A chemical formula can be defined as the way of presenting the information regarding the chemical proportions of the atoms which are present in the given molecule or the chemical compound by making use of
(b)
Interpretation:
The oxide which is most ionic and most covalent in nature is to be determined.
Concept introduction:
An oxide can be defined as a chemical compound which consists of at least one atom of oxygen and a metal element in its chemical formula.
(c)
Interpretation:
The oxide which is most acidic and most basic in nature is to be determined.
Concept introduction:
An oxide can be defined as a chemical compound which consists of at least one atom of oxygen and a metal element in its chemical formula. Acidic oxides are those which when made to react with water forms acid and when made toreact with base forms the corresponding salt. Basic oxides are those which when made to react with water forms base and when made to react with acid forms the corresponding salt.
(d)
Interpretation:
The oxide that can react with both hydroxide and H+ ions is to be determined.
Concept introduction:
A binary hydride is a chemical compound in which a given element is bonded to hydrogen and hydrogen atom acts as a more electronegative atom.
