Select incorrect reduction process

`2[Ag(CN)_(2)]^(-) + Zn rarr [Zn(CN)_(4)]^(2-) + 2Ag`

`CuO + H_(2) rarr Cu + H_(2)O`

`ZnO + H_(2) rarr Zn + H_(2)O`

`MgO + C rarr Mg + CO`

`2[Ag(CN)_(2)]^(-) +Zn to [Zn(CN)_(4)]^(2-)+2Ag `

`CuO+H_(2) to Cu+H_(2)O`

`ZnO+H_(2) to Zn +H_(2)O`

`MgO+C to Mg +CO`

`2[Ag(CN)_(2)]^(-) + Zn rarr [Zn(CN)_(4)]^(2-) + 2Ag`

`2FeO + C overset(Delta)rarr Fe + CO`

`8 AI + 3Mn_(3)O_(4) overset(Delta)rarr 4 Al_(2)O_(3) + 9 Mn`

`2ZnS + C overset(Delta)rarr 2ZnS + CS_(2)`
