Balancing Chemical Equations

In chemical reactions, sets of compounds interact with each other to form new compounds. Chemists use equations to describe these interactions. Like mathematical equations, chemical equations conform to a set of rules. This allows equations to provide detailed information about a reaction.

Covalent Bond Energy

Eating, putting gas in a car and throwing a log on a campfire all involve adding energy to a system. In each case, the energy is added in the form of covalent bond*s that hold atoms together in molecules.

Charles' Law

This illustration explores the relationship between the temperature and volume* of an ideal gas

Boyle's Law

On Earth, matter exists in one of three states: solid, liquid, or gas. Matter in each state exhibits distinct characteristics. Gases, for example, do not have a fixed volume* or shape.
