(a)
Interpretation:
The gas in the given illustration is to be classified as an element, a compound, or a mixture of gases.
Concept introduction:
The substance which is pure and cannot be broken down into simpler forms is known as an element. A compound is a substance that contains two or more elements and can be broken down into elements during a
(b)
Interpretation:
The gas in the given illustration is to be classified as an element, a compound, or a mixture of gases.
Concept introduction:
The substance which is pure and cannot be broken down into simpler forms is known as an element. A compound is a substance that contains two or more elements and can be broken down into elements during a chemical reaction. When two or more substances are mixed together, it is termed as a mixture.
