Solution

(1)
A double displacement reaction will occur, with lead sulphate precipitating out of solution, it being almost insoluble in water
Pb(NO3)2 (aq) + Na2SO4 (aq) → PbSO4 (s) + 2NaNO3 (aq)

(2)

It is a single replacement reaction where zinc metal displaces the hydrogen to form hydrogen gas and zinc chloride, a salt
Zn+HCl=H2+ZnCl2
