• a)

  2 NaCl + Pb(NO3)2 → PbCl2 + 2 NaNO3

  b)

  2 NaCl + Pb(NO3)2 → PbCl2 + 2 NaNO3

  c)

  Cu(NO3)2 + Na2S → CuS + 2 NaNO3

• a) 2NaCl (aq) + Pb(NO3)2(aq) —> 2NaNO3 (aq) + PbCl2(s)

  Since a precipitate is formed, the chemical reaction occurs

  b) Li2SO4 (aq) + Pb(C2H3O2)2 (aq) —-> 2LiC2H3O2 (aq) + PbSO4 (s)

  Since a precipitate is formed, the chemical reaction occurs.

  c) Cu(NO3)2 (aq) + Na2S (aq) —> CuS (s) + 2NaNO3 (aq)

  Since a precipitate is formed, the chemical reaction occurs.
