Answer 2

(a) Explain the terms 'valency' and 'variable valency'.

$\red{->}$Valency is defined as the combining capacity of an element. ..Some elements differ in their capacity to combine with other elements depending on the nature of the reaction; this property is called variable valency. For example, Iron (Fe) can have a valency of both 2 and 3.
