Question

Which phrase best describes a rock? A. a chemical arranged in a lattice B. a gabbro of minerals C. a mixture of crystals D. a fire-formed crystal PLZ AWNSER

Answer 1

The answer is B because :
A=The oppositely-charged ions are arranged in a regular way to form a giant ionic lattice. It is a 'lattice' because the arrangement is a regular one and 'giant' because the arrangement is repeated many times with large numbers of ions. Ionic compounds often form crystals as a result.
B=Gabbro is a dark, medium- to coarse-grained intrusive igneous rock composed of calcium plagioclase, pyroxene, and minor olivine, but no quartz. It is the intrusive equivalent of a basalt.
C=The crystallization of an organic compound can produce a mixture of crystalline solids with different solid-state structures (polymorphs).[1] No convenient method now exists to separate crystals of a single polymorph from a mixture of crystals of different polymorphs.
D= a fire formed crystal and that is not a rock.

Answer 2

Hi there :)


I would go with B. a gabbro of minerals.
