If a solid `A^(o+)B^(ɵ)` having `ZnS` Structure is heated so that the ions along two of the axis passing throgh the face centre particles are lost and bivalent ion `(Z)` enters herre to maintain the electrical neutrality, so that the new formula unit becomes `A_(x)B_(y)C_(c)`, report the value of `x + y + c`.

If solid A^(+)B^(-) having ZnS Structure is heated so that the ions along two of the axis passing through the face center particles are lost and bivalent ion (Z) enters here to maintain the electrical neutrality,so that new formula unit becomes A_(x)B_(y)Z_(c) Report the value of x+y+c

In a compound, atom A form ccp arrangement, atom B present in 12.5% of the tetrahedral voids and atom C present in 25% of the octahedral voids and rational formula is expressed as A_(x)B_(y)C_(z) then value of (x+y+z) is:

A compound AB has zinc blende structure with Aatoms at corners and face centre of the unit cell.If all the atoms present in one body diagonal are removed,the formula of the compound becomes A_(x)B_(y) .The sum (x+y) is

A spinal is an important class of oxides consisting of two types of metal ions with oxides ions arranged in CCP layer. The normal spinal has one-eighth of the tetrahedral holes occupied by one type of metal ion and one-half of the octahedral holes occupied by another type of metal ion. such a spinal is formed by Zn^(2+), Al^(3+) and O^(2-) in the tetrahedral holes. if formula of the compound is Zn_(x)Al_(y) O_(z) , then find the value of (x + y + z) ?
