Question

Arrange the following sequence in order to derive the formula of zine oxide.
(a) The valencies of ions formed by zine and oxygen are written below without positive and negative sign.
(b) The positive ion that is `Zn^(+2)` followed by the negative ion , that is oxide `(O^(-2)` ion are written with ther charges.
(c ) The valencies of zinc and oxide ion have common factors and hence they are divided by their highest common factor.
(d) The magnitude of valencies of the ions should be interchanged and written as subscripts on right side of the respective ions.
A. badc
B. abcd
C. bacd
D. cabd

Answer 1

Correct Answer - 3
(i) The posiitive ion that is `Zn^(+2)` followed by the negative ion that is `O^(-2)` are written with their charges.
(ii) The valencies of ions formed by zine and oxygen and are written below without positive and negative sign. (iii) The valencies of zinc and oixde have common factors and hence they are divided by the highest common factor.
(iv) The magnitude of the valencies of the ions should be interchanged and written as subscripts on right side of the respective ions.
