(a)
Interpretation:
The silver bar is to be classified as an element, compound, homogeneous mixture, or heterogeneous mixture.
Concept introduction:
An element is the basic unit of a substance that cannot be broken down into any smaller units. A compound is made up of elements through the formation of
(b)
Interpretation:
The silver ore is to be classified as an element, compound, homogeneous mixture, or heterogeneous mixture.
Concept introduction:
An element is the basic unit of a substance that cannot be broken down into any smaller units. A compound is made up of elements through the formation of chemical bonds, and it can be broken down into the constituent elements. A mixture is made up of elements but without the formation of chemical bonds between them. The mixture exhibits the properties of its constituent elements. Two types of mixtures are there: homogenous and heterogeneous. Homogeneous mixtures are uniform and have fixed compositions. On the other hand, heterogeneous mixtures are non-uniform, and their composition is not fixed.
(c)
Interpretation:
The silver oxide is to be classified as an element, compound, homogeneous mixture, or heterogeneous mixture.
