Final answer:

Elements and compounds can be distinguished based on their chemical composition, with compounds being combinations of elements in fixed ratios.


Explanation:

Elements are substances that cannot be broken down into simpler substances by chemical means, such as oxygen and hydrogen. Compounds are substances composed of two or more elements that are chemically combined in a fixed ratio, like water (H2O).

Salt: compound, pure water: compound, soil: heterogeneous mixture, salt water: homogeneous mixture, pure air: homogeneous mixture, carbon dioxide: compound, gold: element, bronze: heterogeneous mixture.
