Chemical bonds refer to the interaction that atoms have between other atoms. This is either covalent/(dative), ionic or metalic.
A chemical equation can refer to either full or half (ionic level) which will show the movement of electrons. Full equations show the whole process of a reaction.
Chemical reactions are when reagents are added together, they give products.
The relationship between bonds, EQ and reactions is that equations show the process of the reactions, and bonding is how the reactants are bonding.
