Complete the following reactions.
(i) H2(g)+MmOo(s)→Δ\mathrm{H}_{2(g)} + \mathrm{M}_m\mathrm{O}_{o(s)} \xrightarrow{\Delta}
(ii) CO(g)+H2(g)→Δ\mathrm{CO}_{(g)} + \mathrm{H}_{2(g)} \xrightarrow{\Delta}
(iii) C3H8(g)+3H2O(g)→catalystΔ\mathrm{C}_3\mathrm{H}_{8(g)} + 3\mathrm{H}_2\mathrm{O}_{(g)} \xrightarrow[\text{catalyst}]{\Delta}
(iv) Z_(s)+NaOH_(aq)→↖{\heat} $
Solution:  
(i) H2(g)+MmOo(s)→Δ\mathrm{H}_{2(g)} + \mathrm{M}_m\mathrm{O}_{o(s)} \xrightarrow{\Delta} mM(s)+oH2O(l)m\mathrm{M}_{(s)} + o\mathrm{H}_2\mathrm{O}_{(l)}
(ii) CO(g)+H2(g)→Δ\mathrm{CO}_{(g)} + \mathrm{H}_{2(g)} \xrightarrow{\Delta} CH3OH(l)Methyl alcohol\underset{\text{Methyl alcohol}}{\mathrm{CH}_3\mathrm{OH}_{(l)}}
(iii) C3H8(g)+3H2O(g)→Ni catalyst, 1270 KΔ\mathrm{C}_3\mathrm{H}_{8(g)} + 3\mathrm{H}_2\mathrm{O}_{(g)} \xrightarrow[\text{Ni catalyst, 1270 K}]{\Delta} 3CO(g)+7H2(g)3\mathrm{CO}_{(g)} + 7\mathrm{H}_{2(g)}
(iv) Z(s)+NaOH(aq)→heat\mathrm{Z}_{(s)}+\mathrm{NaOH}_{(aq)} \xrightarrow{\text{heat}} Na2ZnO2(aq)Sod. zincate+H2(g)\underset{\text{Sod. zincate}}{\mathrm{Na}_2\mathrm{ZnO}_{2(aq)}} + \mathrm{H}_{2(g)}
