1.	In the reaction H₂(g) + Br₂(g) --> 2HBr(g) which substance undergoes oxidation? (A) H₂ (B) Br₂ (C) HBr (D) H₂ and Br₂
Answer» NATION:elemental form have oxidation state zeroBoth h2 and Br2 have zero oxidation state. In HBr or H+ BR-, oxidation number of hydrogen is +1 and BROMINE -1.thus hydrogen change its oxidation state from 0 to +1 LOSS of one electron (oxidation)
