Explanation A chemical species is given by A M B N ,where A , B are the symbols of the elements and M , N are the number of atoms of the same element that are present in the same molecule (atomicity). In the question diagram,purple spheres represent iodine atoms while white spheres represent hydrogen atoms. In the reactant picture, A = H , B = I and M = 1 , N = 1. So, formula of reactants = H I . In given product picture, there are 2 molecules of iodine and 2 molecules of hydrogen. So, A = H , M = 2 . So, formula of product is H 2 . Similarly, for iodine, A = I and M = 2 . So, formula of product is I 2 . So, formula of products = H 2 , I 2 . b. General rule for a balanced equation is that the number of individual atoms in the reactant (left hand side) side must be equal to the number of individual atoms in the product side (right hand side)
