<span>The balanced chemical ionic equarion of MgS(aq)+CuCl2(aq) = CuS(s)+MgCl2(aq) would be as follows:
</span><span>Mg2+ + S2- + Cu 2+ + 2 Cl- ==> CuS + Mg2+ + 2 Cl-
Therefore, the net equation would be:
</span><span>Cu 2+ + S 2- ===> CuS
</span><span>
Hope this helps.

Answer:
m = 8.1 kg
Explanation:
Density of metal ball, d = 8.96 g/cm³
Diameter of ball, d = 12 cm
Radius of ball, r = 6 cm
Density of an object=mass/volume
The metal ball is in the shape of sphere whose volume is given by :
Now using formula,
or
m = 8.1 kg
So, the mass of the metal ball is 8.1 kg.
