Answer:
In summary, a polar bond results when different atoms share electrons. One atom will attract the bonding electrons more strongly than the other atom and will acquire more than a half share of these electrons. This leaves the other atom with less than a half share and makes the electron distribution unsymmetrical. On a time-average basis the electrons spending more time with one atom and cause it to have a partial negative charge. The other atom, deficient in electrons, acquires a partial positive charge.

Strontium sulfide react with aqueus copper(ii) nitrate to form strontium (ii)nitrate and copper sulfide. the chemical equation is represented as follows
SrSO4(S) plus CU(NO3)2(aq) -->Sr(NO3)2(aq) PLUS CUSO4(s
the equation is balanced since both cupper and strontium have a valence of two.
