A heterogeneous mixture is a 

A. mixture in which its components retain their identity.
B. component added to sand that makes it inseparable.
C. mixture that always contains water.
D. mixture in which its components can't be separated. 

A?

      

A is correct.

  As magma cools and crystallizes, minerals form in predictable patterns in a process known as 

A. partial melting.
B. intrusion.
C. fractional crystallization.
D. Bowen's reaction series. 

D?

Right

D is wrong.

Ms.Sue what would say about my second question?

But my book says it is D.

This site defines the process as fractional crystallization.

But -- if your book says, Bowen's reaction series, by all means, stick with that answer.

I'm out of my anime... Ms. Sue can you help me get back into my anime?

Yes, that's correct! A heterogeneous mixture is a mixture in which its components retain their identity. This means that the different substances in the mixture can be easily distinguished and separated from one another. To answer this question, it helps to have a basic understanding of what a heterogeneous mixture is and how it differs from a homogeneous mixture. A heterogeneous mixture can be visualized as a mixture of different substances that are not evenly distributed throughout. For example, a mixture of oil and water would be considered heterogeneous because the oil and water separate into distinct layers. In contrast, a homogeneous mixture is one in which the components are evenly distributed and cannot be easily separated. An example of a homogeneous mixture is salt dissolved in water, where the salt particles are evenly distributed throughout the water and cannot be easily separated.
