Concept explainers
(a)
Interpretation : The potting soil should be classified as homogeneous or heterogeneous mixtures.
Concept Introduction : Mixtures are classified depending on their physical and chemical nature. If they exist in single phase, they can be considered as homogeneous mixtures. But if more than one phase is formed, they are known as heterogeneous mixtures.
(b)
Interpretation : The white wine should be classified as homogeneous or heterogeneous mixtures.
Concept Introduction : Mixtures are classified depending on their physical and chemical nature. If they exist in single phase, they can be considered as homogeneous mixtures. But if more than one phase is formed, they are known as heterogeneous mixtures.
(c)
Interpretation : The sock drawer should be classified as homogeneous or heterogeneous mixtures.
Concept Introduction : Mixtures are classified depending on their physical and chemical nature. If they exist in single phase, they can be considered as homogeneous mixtures. But if more than one phase is formed, they are known as heterogeneous mixtures.
(d)
Interpretation : The window glass should be classified as homogeneous or heterogeneous mixtures.
Concept Introduction : Mixtures are classified depending on their physical and chemical nature. If they exist in single phase, they can be considered as homogeneous mixtures. But if more than one phase is formed, they are known as heterogeneous mixtures.
(e)
Interpretation : The granite should be classified as homogeneous or heterogeneous mixtures.
