A) The units of surface tension are dynes\[c{{m}^{-1}}\]
B) The units of viscosity coefficient of a liquid are "poise"
C) \[CsCl\]crystallizes in body centred cubic type of lattice
D) The co-ordination number of\[{{S}^{2-}}\]in\[ZnS\]is 6
Correct Answer: D
Solution :
Zinc blende\[(ZnS)\]has CCP arrangement of\[{{S}^{2-}}\] and \[Z{{n}^{2+}}\]in alternative tetrahedral sites. The co-ordination number of\[Z{{n}^{2+}}=4\]and\[{{S}^{2-}}=4\] in\[ZnS\].You need to login to perform this action.
