Document Summary

A carbon monoxide molecule contains a carbon atom and an oxygen atom held together by a chemical bond. Atoms are the submicroscopic particles that constitute the fundamental building blocks of ordinary matter. Molecules are two or more atoms joined in a specific geometrical arrangement. To understand substances around us, we must understand the atoms and molecules that compose them. Chemistry is the science that seeks to understand the behaviour of matter by studying the behaviour of atoms and molecules. Scientific knowledge is based on observation and experiment. A hypothesis is a tentative interpretation or explanation of the observations. Experiments are highly controlled procedures designed to generate observations. Scientific law is a brief statement that summarizes past observations and predicts future ones. The law of conservation of mass states, in a chemical reaction, matter is neither created nor destroyed. A law summarizes a series of related observations, while a theory gives the underlying reasons for them.
