उत्तर
Fundamental laws which are involved in every equation:
A chemical equation consists of formulae of reactants connected by a plus sign (+) and arrow (→) followed by the formulae of products connected by the plus sign (+).
The sign of an arrow (→) is to read 'to form'. It also shows the direction in which the reaction is predominant.
The fundamental law followed by every equation is 'Law of Conservation of Mass'.
