(B) `KClO_(3) overset(Delta)underset(MnO_(2)) to KCl + 3/2 O_(2)`
`Pb(NO_(3))_(2) overset(Delta) to PbO + 2NO_(2) + 1/2 O_(2)`
`NaNO_(3) overset(Delta) to NaNO_(2) + 1/2O_(2)`
(C ) 2-ethylanthraquinol `overset(O_(2)(air))underset(H_(2)//Pd) to "2-ethylanthraquinone" + H_(2)O_(2)`
( D) `2H_(3)BO_(3) + 2NaOH + 2H_(2)O to Na_(2)[B_(2)(O_(2))(OH)_(4)] + 4H_(2)O`
