Galena (an ore ) is partially oxidised by passingare throughit at hightemperature. Aftersome time,the passageof air isstopped,but theheating is continued in a closed furance such thatthe contents undergoself - reduction. Theweight (in kg )of Pbproduced perkg of O_(2)consumed is- (O = 16, s = 32, Pb = 207)

Answer»


SOLUTION :`PBS+ O_(2) to Pb + SO_(2)`
mol of `O_(2)` = mol of Pb
`(1000 (g))/(32) = ("Wt. of Pb (g)")/(207) 1 `
