Answer:
Two equivalent resonance forms can be drawn
Explanation:
In Lewis structure, total valence electrons of constituting atoms are used to draw structure by obeying octet of all atoms and duet of hydrogen atoms.
Least electronegative atom (except hydrogen atom) are considered as central atom.
In , S is the least electronegative atom. Hence it is the central atom.
Number of valence electron of S is 6 and valence electron of O is 6.
So, total number of valence electrons in is 18.
By using this 18 electrons and obeying octet for S and O, two equivalent resonance forms can be drawn.
Structure of resonance forms has been given below.

Answer: a)
b) 1 mole of is produced.
Explanation:
According to the law of conservation of mass, mass can neither be created nor be destroyed. Thus the mass of products has to be equal to the mass of reactants. The number of atoms of each element has to be same on reactant and product side. Thus chemical equations are balanced.
The skeletal equation is:
The balanced equation will be:
Thus the coefficients are 2, 3 , 10 , 4 , 3 , 2 and 5.
b) Oxidation:
Reduction:
Net reaction:
When 1 mole of is produced, 1 mole of
is produced.
