Pb(NO3)2 + 2LiOH → Pb(OH)2 + 2LiNO3Cu(NO3)2 + 2Na2S → CuS + 4NaNO3Na2SiO3 + 2HCl → SiO2 + 2NaCl + H2OBa(OH)2 + 2HNO3 → Ba(NO3)2 + 2H2O2)
H2SO4 + Al(OH)3 → Al2(SO4)3 + 3H2O2Al + 6HCl → 2AlCl3 + 3H22FeCl3 + 6KOH → 2Fe(OH)3 + 6KCl3)
K3PO4 + FeS → no reaction, because K3PO4 and FeS do not react with each other
K2S + ZnSO4 → ZnS + K2SO4
Na2SO3 + Zn(OH)2 → no reaction, because Na2SO3 and Zn(OH)2 do not react with each other.
