A balanced equation for the given reaction has to be written. “Ammonia is formed by the reaction of nitrogen and hydrogen” Concept Introduction: Balancing the equation: There is a Law for conversion of mass in a chemical reaction i.e., the mass of total amount of the product should be equal to the total mass of the reactants. First write the skeletal reaction from the given information. Then count the number of atoms of each element in reactants as well as products. Place suitable coefficients in front of reactants as well as products until the number of atoms on each side (reactants and products) becomes equal.
