Water gas contains `CO and H_(2)` in mole ratio, 1:1. A nickel ore containing `Ni_(2)O_(3)` may be reduced into `Ni` as
`Ni_(2)O_(3)(s)+3H_(2)(g)rarr2Ni(s)+3H_(2)O(g)` But due to presence of CO(g), the nickel formed get converted into `Ni(CO)_(x)(g).` Both the reaction occurs `100%` If 240 gm water gas is needed to convert one mole of `Ni_(2)O_(3)(s)` into `Ni(CO)_(x)(g),` the value of x is:
