A sub-discipline of chemistry, that is, stereochemistry includes the study of the comparative spatial alignment of atoms, which produce the composition of the molecules and their manipulation. The examination of stereochemistry aims at stereoisomers that by definition exhibits the similar sequence of bonded atoms and molecular formula, however, vary in the three-dimensional orientations of their atoms in space.
The products. Without a balanced chemical equation, there is no reaction that can take place. The products is the final reation and the reactants help the final reaction take place.
