Interpretation: Table salt must be classified as an element, compound, or mixture.
Concept Introduction: A compound that is made up of two or more chemical components that are not chemically linked with each other is said to be a mixture.
The simplest form of matter consisting unique set of properties is said to be elements. They are pure substances made up of only one type of atom.
The chemical combination of two or more elements in a fixed proportion results in the formation of a compound.

Answer to Problem 53A
Compound.
Explanation of Solution
Table salt is made up of the chemical combination of two atoms, sodium and chlorine. The chemical combination of these atoms makes up table salt and thus, it is classified as a compound.
Interpretation: Salt water must be classified as an element, compound, or mixture.

Answer to Problem 53A
Mixture.
Explanation of Solution
In salt water, the salt is dissolved in water and the mixture obtained has a uniform composition throughout. Saltwater is a homogenous mixture of water and salt. Thus, it is classified as a mixture as the constituents are not
Interpretation: Sodium must be classified as an element, compound, or mixture.
