In the classification of matter, how many distinct layers can a heterogeneous mixture have?
A
Exactly three layers
B
Two or more layers
C
No layers at all
D
Only one layer
Verified step by step guidance1
Understand that a heterogeneous mixture is a mixture where the components are not uniformly distributed, meaning you can see different parts or phases within the mixture.
Recall that in a heterogeneous mixture, the different substances often separate into distinct regions or layers because they have different physical properties like density or solubility.
Recognize that the number of layers in a heterogeneous mixture is not fixed; it can be two or more depending on how many different substances or phases are present and how they separate.
Contrast this with homogeneous mixtures, which have only one uniform layer because the components are evenly distributed at the molecular level.
Conclude that the correct classification for the number of layers in a heterogeneous mixture is 'two or more layers' since it must have at least two distinct parts but can have more.
