What is a chemical equation?

Unlike mathematical equations, the two sides are separated by an arrow, that indicates that the reactants form the products and not the other way round.

A large number of chemical equations are more complicated than the simple ones you will see in this section. They are reversible, which means that the reactants react together to form the products, but as soon as the products are formed, they start to react together to reform the reactants!

Reversible equations proceed in both directions at once, with reactants forming products and products forming reactants simultaneously. Eventually, the system settles down and a balance (an equilibrium) is reached, with the reactants and products present in stable concentrations. This does not mean that the reaction stops, merely that it proceeds in both directions at the same rate, so that the concentrations do not change.

Reversible reactions are indicated with a double arrow as shown in the example below:

How chemical reactions happen

Chemical reactions are processes of transforming one substance to another through changing chemical bonds. The study of chemical reactions is at the core of chemistry. This activity is a series of virtual experiments for studying how chemical reactions happen. We will focus on organic chemical reactions and will not address issues related to biochemical reactions that are mostly mediated by the aqueous environment. Throughout this activity, when we say bonds, we only mean covalent bonds.
