S sulfur
Na2SO3 + 2HCl -> 2NaCl + H2SO3
oxidation number of I is -1. oxidation number of F is +1.
The formula is Na2SO3 , because Na have 1 valence electrone and SO3 is a polyatomic with 2 valence electrons so u cross multiply Na1 * SO3(2) =Na2SO3
Zn has oxidation number +2; S has oxidation number -2
