Answer 1

[tex]2SO_2 + O_2 =2 SO_3 \\ 2NO + O_2= 2NO_2 \\ Na_2O + H_2O= 2NaOH \\ 2Al(OH)3 - Al_2O_3 + 3H_2O [/tex]
iar ex. 2
Zn +2 HCl = ZnCl2 + H2
1mol/2moli/1mol/1mol
Zn+ H2SO4 = ZnSo4 + H2
1mol/1mol/1mol/1mol
Fe+ CuSo4= FeSO4+ Cu
1mol/1mol/1mol/1mol
2Al+ 3Pb(NO3)2 = 2Al(NO3)3 + 3Pb
2moli/3moli/2moli/3moli
NaOH+ HCl = NaCl + H2O
1mol/1mol/1mol/1mol
2KOH+ H2SO4=K2SO4+2H2O
2moli/1mol/1mol/2moli
