Please select the word from the list that best fits the definition Composed of one type of compound molecule compound mixture chemical formula molecular formula pure substance

Answer 1

Answer:

Pure substance

Explanation:

Molecule: contains more atoms of different elements. An example is CO2 molecule. So this option is wrong.

Compound: All compounds are molecules so this option is also wrong.

Mixture: Refers to the union of more than one substances that can be separated.

Chemical and Molecular formular: Represents the constituents of a molecule. This is wrong.

Pure substance: This is the correct option. For an object to be considered pure, it must be composed entirely of one compound.
