WebFeb 10, 2024 · The results show that microwave roasting with 20% Na2O2 at 600 °C for 15 min adequately transforms ZnS, ZnCO3 and Zn2SiO4 into ZnO and avoids the generation of Zn2SiO4. Further, 0.5 mol/L NTA3− (nitrilotriacetic acid) is especially effective as a complex additive for complexes with Zn2+ as Zn (NTA)24−. WebCoordination number of Zn in ZnS (zinc blende) is A 6 B 4 C 8 D 12 Medium Solution Verified by Toppr Correct option is B) In zinc blende structure (ZnS), sulphide ions are face-centred and zinc is present in alternate tetrahedral voids. Formula is ZnS. Coordination number of Zn is 4 and that of sulphide is 4.
