Consider two chemical reactions (A) and (B) that take place during metallurgical process : (A) {ZnCO}_{3({s})} { ───▸}↖ {\\Delta} {ZnO}_{({s})}+{CO}_{2({g})} (B) 2 {ZnS}_{(s)}+3 {O}_{2({g})} { ───▸}↖ {\\Delta} 2 {ZnO}_{({s})}+2 {SO}_{2({g})} The correct option of names given to them respectively is : [20 Jul 2021 Shift 2]

Correct Answer is : (A) is calcination and (B) is roasting

(A) is calcination and (B) is roasting

Both (A) and (B) are producing same product so both are roasting

Both (A) and (B) are producing same product so both are calcination

(A) is roasting and (B) is calcination
