WHAT IS FORMULA OF COPPER GLANCE AND ZINC BLEND

Answer 1

copper glance = Cu2S
zinc blend = ZnS

Answer 2

copper glance - a heavy grey mineral that is an ore of copper. chalcocite. atomic number 29, copper, Cu - a ductile malleable reddish-brown corrosion-resistant diamagnetic metallic element; occurs in various minerals but is the only metal that occurs abundantly in large masses; used as an electrical and thermaal.....................

Wurtzite has a hexagonal structure, while zincblende is cubic. It is characterized by single bonds between each atom and maintenance of a 1:1 zinc to sulfur ratio. Since the number of atoms in a single unit cell of Zn and S is the same, it is consistent with the formula ZnS.
