Which statement best explains how matter forms different types of mixtures?
A
Mixtures are formed when elements lose their identity and become a single pure substance.
B
Matter forms mixtures only when substances react chemically to produce new compounds.
C
Mixtures can only be formed from gases and cannot involve solids or liquids.
D
Matter forms mixtures when two or more substances are physically combined without undergoing chemical changes, resulting in either homogeneous or heterogeneous mixtures.
Verified step by step guidance1
Understand that mixtures are combinations of two or more substances where each substance retains its own chemical identity.
Recognize that in mixtures, the substances are physically combined, meaning no chemical bonds are formed or broken during the mixing process.
Identify that mixtures can be classified as homogeneous (uniform composition throughout) or heterogeneous (non-uniform composition).
Note that mixtures can involve any state of matter: solids, liquids, or gases, and are not limited to any particular phase.
Conclude that matter forms mixtures by physically combining substances without chemical reactions, which distinguishes mixtures from pure compounds or elements.
