Question

number of elements on the reactants side and product side by step by step
Na+cl2 ----- Nacl

N2+H2 ----NH3

Answer 1

Answer:

on the reactant side Na will be two and on the product side it will be two again hence it gets balanced as the no. of atoms become equal.

in the next question the product side becomes 2 and the reactant side H2 will become 3H2

Answer 2

Answer:

Explanation:

N2+H2 ----NH3

Element       No. of atoms in LHS     No. of atoms in RHS

N                               2                                            1

H                               2                                            3

Na+cl2 ----- Nacl

Element       No. of atoms in LHS     No. of atoms in RHS

Na                         1                                        1

Cl                           2                                        1
