option 2 - the sample is a compound. Compound sample: A compound contains a bond formed by a chemical reaction between two or more atoms. For instance, 2H2(g) + O2(g) = 2H2O.

Compound homogeneous mixture: A material in which more than one element is produced but both remain in the same phase. There will be consistency in the mixture. As an example, gas with gas, liquid with liquid, and so on. As an example, consider air, which is a gaseous mixture of oxygen, nitrogen, and carbon dioxide. Compound Heterogeneous mixture: A mixture in which the compound or elements used to make the mixture are in different phases. As an example, consider chalk (CaCO3 (solid) in water (H2O (liquid), which is a heterogeneous mixture.
