What are 3 ways that compounds and mixtures differ

3 ways to understand the differences between compounds and mixtures are described below in explanation.

Explanation:

1. In a mixture, no new product is formed. It is a simple tacking of two molecules without any chemical reaction occurring. For example water and sand. Compound is a new substance formed by chemical reactions occurring between various molecules. For example, carbon and oxygen combine to form carbon dioxide.

2. A compound is always homogeneous whereas a mixture can be homogeneous or heterogeneous.

3. Compounds have a fixed boiling and melting temperature. Whereas, mixtures do not have a definite melting and boiling temperature.
