Solution

The correct option is A I,II, III and IV
Decomposition of H2O2:2H2O2(l)O2(g)+2H2O(l)

Industrially, H2O2 is prepared by the auto-oxidation of 2-alklylanthraquinols. 2KClO3150300 C−−−−−−2KCl+3O2

2Pb(NO3)2200470 C−−−−−−2PbO+4NO2+O2

2NaNO32NaNO2+O2

Synthesis of sodium perborate:
Na2B4O7+2NaOH+4H2O22NaBO3+5H2O
