Answer 1

Solution :- (39 le. all of the above / Explanats:- oxidates state as o in H2oz is - -1 oxidats state Can Change to -2 (redicters) or o Copidalins) :- gf act both oxidad & redueel 2H202 > 2420+ 02 oxidisiy agent senice som ? ob proportionales also , H2oz due to its oxidesing property, j used as a bleaching agent Nitrogen comfound which is Paramagniteris (9) Nol The mala facter in Photo Chemical smag and and - dis proportionatin rain is 15. no

Non mital oxides react with water to produce Tc acid solutions Example sazth20 Hz son, no2f720 and HNO3 and u acid is formula for iodors Tb. H102 ] hyd oxidation State Can not be observed for is te. +7 7 do ni Can not expand its octet as it has no vacant erbital ) Sulfur is mined using I do the frasch proces to the process, named after its inventer Hermann frasch
