(a)
Interpretation:
The sodium metal is to be classified as an element, compound, or 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 chlorine gas is to be classified as an element, compound, or 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.
(c)
Interpretation:
The sodium chloride is to be classified as an element, compound, or 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.
(d)
Interpretation:
The salt water is to be classified as an element, compound, or 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.
