(a)

Interpretation Introduction

Interpretation: The oxidation state of iron and its electronic configuration in ${\text{FeO}}_{\text{4}}{}^{\text{2-}}$ is to be stated. Volume of nitrogen gas that can be formed at $25\text{°C}$ and $\text{1}\text{.50}\text{atm}$ if $\text{25}\text{ml}$ of a $0.243M$ ${\text{FeO}}_{\text{4}}{}^{\text{2-}}$ solution is allowed to react with $\text{55}\text{ml}$ of $1.45\text{M}$ aqueous ammonia is to be determined.

Concept introduction: Electronic configuration is used to describe the distribution of the electrons in the orbitals of an atom. Structure of an atom can be defined by its electronic configuration. It can also be used to denote an atom which is ionized to a cation or anion formed by the loss or gain of electrons in their respective orbitals.

To determine: The oxidation state of iron and its electronic configuration in ${\text{FeO}}_{\text{4}}{}^{\text{2-}}$.
