Question

How do solutions differ from compounds? From other mixtures?

a) Solutions consist of a solute dissolved in a solvent, while compounds are chemically bonded substances.
b) Solutions involve the mixing of substances at the molecular level, while compounds are made of distinct elements.
c) Solutions have variable compositions and can be homogeneous or heterogeneous, while compounds have fixed compositions.
d) Solutions are formed through dissolution, while compounds are formed through chemical reactions.

Answer 1

Solutions differ from compounds and mixtures in terms of their composition, molecular mixing, variable compositions, and formation processes. Correct option is c.

Step-by-step explanation:

Solutions differ from compounds and other mixtures in several ways:

1. Solutions consist of a solute dissolved in a solvent, while compounds are chemically bonded substances. For example, salt dissolved in water is a solution, while sodium chloride (salt) is a compound.
2. Solutions involve the mixing of substances at the molecular level, while compounds are made of distinct elements. In a solution, the solute particles are dispersed and separated at the molecular level throughout the solvent. In a compound, the elements are chemically bonded together to form a new substance with unique properties.
3. Solutions have variable compositions and can be homogeneous or heterogeneous, while compounds have fixed compositions. A solution can have different amounts of solute dissolved in a solvent, resulting in different concentrations. Compounds, on the other hand, have a fixed ratio of elements and cannot be varied.
4. Solutions are formed through dissolution, while compounds are formed through chemical reactions. Dissolution is a physical process where a solute combines with a solvent to form a solution. Compounds are formed when two or more elements chemically react to form a new substance.
