1. 3H2 + N2 = 2NH3
2. 2H2S + 3O2 = 2H2O + 2SO2
3. 3BaCl2 + Al2(SO4)3 = 2AlCl3 + 3BaSO4 (put a down arow)
4. 2K + 2H2O = 2KOH + H2 (put an up arrow)

My chem is really rusty, so this is all I can answer: Sorry about any mistakes or about any reactions that do not occur.
1) 3H2 + N2 = 2NH3
2) H2S + O2 = H2O + SO2
3) 3BaCl2 + Al2(SO4)3 = 2AlCl3 + 3BaSO4
4) 2K + 2H2O = 2KOH + H2

1) 3H2+N2--->2NH3
2)2H2S +3O2--->2 H2O+ 2SO2
3) 3BaCl2+ Al2 (SO4)3 ---> 2Al Cl3 +3 BaSO4
4) 2K +2H2O---> 2KOH + H2

1.H+N3=NH3
2.S+H2=H2S
3.BaCl+Al2(SO4)3·16H2O=AlCl3+BaSO4
4.K+H2O=KOH+H2
