Concept explainers
a)
Interpretation:Whether orange juice is compound, homogenous mixture or heterogeneous mixture should be classified.
Concept introduction:In homogeneous mixture, compounds are uniformly distributed throughout mixture. Such mixtures are blood plasma, tap water, and air. On the other hand in heterogeneous mixture, compounds are not uniformly distributed and their concentration and ratio vary throughout mixture. Such mixtures are soil and sand.
b)
Interpretation:Whether Vegetable soup is compound, homogenous mixture or heterogeneous mixture should be classified.
Concept introduction:In homogeneous mixture, compounds are uniformly distributed throughout mixture. Such mixtures are blood plasma, tap water, and air. On other hand in heterogeneous mixture, compounds are not uniformly distributed and their concentration and ratio vary throughout mixture. Such mixtures are soil and sand.
c)
Interpretation:Whether cement is compound, homogenous mixture or heterogeneous mixture should be classified.
Concept introduction:In homogeneous mixture, compounds are uniformly distributed throughout mixture. Such mixtures are blood plasma, tap water, and air. On other hand in heterogeneous mixture, compounds are not uniformly distributed and their concentration and ratio vary throughout mixture. Such mixtures are soil and sand.
d)
Interpretation:Whether calcium sulfate is compound, homogenous mixture or heterogeneous mixture should be classified.
Concept introduction:In homogeneous mixture, compounds are uniformly distributed throughout mixture. Such mixtures are blood plasma, tap water, and air. On other hand in heterogeneous mixture, compounds are not uniformly distributed and their concentration and ratio vary throughout mixture. Such mixtures are soil and sand.
e)
Interpretation:Whether tea is compound, homogenous mixture or heterogeneous mixture should be classified.
Concept introduction:In homogeneous mixture, compounds are uniformly distributed throughout mixture. Such mixtures are blood plasma, tap water, and air.
