Answer:
B) Socium chloride: Compound, Salt water: Mixture
Step-by-step explanation:
A compound is the result of a combination of elements, which will be added by bonds: ionic, covalent or metallic. Sodium chloride is the combination of ions Na⁺ and Cl⁻, and it's an ionic compound.
A mixture is a substance that is formed by mixing two or more compounds. The elements of the compounds do not react between them and do not form bonds. In a mixture, an ionic compound may be dissolved in its ions. There'll be a solvent (which can dissolve the other compounds and will be in more quantity), and solutes (which will be dissolved and will be in less quantity). So in salt water, the water is the solvent and sodium chloride the solute, and it's a mixture.
