Balancing Chemical Equations
... Scientists use chemical equations as a shorthand way to represent the reactions that occur between substances. Because of the law of conservation of matter, these equations must be balanced. In other words, the number of atoms of each element must be conserved. For example, look at the reaction of h ...

Chemical equilibrium
In a chemical reaction, chemical equilibrium is the state in which both reactants and products are present in concentrations which have no further tendency to change with time. Usually, this state results when the forward reaction proceeds at the same rate as the reverse reaction. The reaction rates of the forward and backward reactions are generally not zero, but equal. Thus, there are no net changes in the concentrations of the reactant(s) and product(s). Such a state is known as dynamic equilibrium.
