Which type of mixture is mixture b?

Heterogeneous mixture.

Explanation:

Hello,

In this case, one must remember that homogeneous mixtures are substances that do not present a distinguishable difference among its constituents so it looks like one single substances while heterogeneous mixtures are substances that actually present a distinguishable difference among its constituents so one could differentiate them.

In such a way, since mixture B has ammonium chloride which is highly soluble in water and sand which is poorly soluble in water, the resulting mixture is heterogeneous.

Best regards.
