Solution

(a)

The physical states of the reactants &products are shown by putting the"state symbol" just after their symbols or formulae in an equation.

Eg.,
$Z n (s) + H_{2} S O_{4} (a q) ⟶ Z n S O_{4} (a q) + H_{2} (g)$

Here, s = Solid state & aq=aueous state

(b)

(c)

The balanced equation is given below:

$F e S O 4 (a q) + 2 N a O H (a q) ⟶ F e (O H)_{2} (s) + N a_{2} S O_{4} (a q)$
