Complete the followings equations

1.  $\mathrm{PbS}\left(\mathrm{s}\right)+{\mathrm{H}}_{2}{\mathrm{O}}_{2}\left(\mathrm{aq}\right)\to$

2.  $\mathrm{CO}\left(\mathrm{g}\right)+2{\mathrm{H}}_{2}\left(\mathrm{g}\right)\underset{\mathrm{Catalyst}}{\overset{\mathrm{Cobalt}}{\to }}$

(i) When PbS react with hydrogen peroxide, then PbSO4 and water are formed.
$\mathrm{PbS}\left(\mathrm{s}\right)+{\mathrm{H}}_{2}{\mathrm{O}}_{2}\left(\mathrm{aq}\right)\to {\mathrm{PbSO}}_{4}+4{\mathrm{H}}_{2}\mathrm{O}$
(ii) When carbon mono-oxide reacts with hydrogen in the presence of cobalt catalyst, then methanol is formed.
$\mathrm{CO}\left(\mathrm{g}\right)+2{\mathrm{H}}_{2}\left(\mathrm{g}\right)\underset{\mathrm{Catalyst}}{\overset{\mathrm{Cobalt}}{\to }}{\mathrm{CH}}_{3}\mathrm{OH}\left(\mathrm{l}\right)$
