CHEMICAL REACTION

1. A chemical reaction is a chemical change which forms new substances. A chemical reaction may be represented by a chemical equation, which indicates the number and type of each atom, as well as their organization into molecules or ions. A chemical equation uses the element symbols as shorthand notation for the elements, with arrows to indicate the direction of the reaction.

2. A conventional reaction is written with reactants on the left side of the equation and products on the right side. The state of matter of the substances may be indicated in parenthesis (s for solid, l for liquid, g for gas, aq for aqueous solution). The reaction arrow may go from left to right or there may be a double arrow, indicating reactants turn to products and some product undergoes the reverse reaction to reform reactants.

3. While chemical reactions involve atoms, typically only the electrons are involved in the breaking and formation of chemical bonds. Processes involving the atomic nucleus are called nuclear reactions.

4. The substances that participate in a chemical reaction are called reactants. The substances that are formed are called products. The products have different properties from the reactants...
