умоляю 2 и 3 нада зделать​

1) S+O2=SO2

SO2+H2O=H2SO3

H2SO3+2NaOH=Na2SO3+2H2O

Na2SO3+2HCl=2NaCl+SO2+H2O

2) Fe+2HCl=FeCl2+H2

FeCl2+2NaOH=Fe(OH)2+2NaCl

Fe(OH)2=(t) FeO+H2O

3) 4Al+3O2=2Al2O3

Al203+3H2SO4=Al2(SO4)3+3H2O

Al2(SO4)3 +6NaOH=Al(OH)3 +3Na2SO4

Al(OH)3+NaOH=Na[Al2(OH)4]

Al203+6HCl=2AlCl3+3H2O3

AlCl3+3Na=3NaCl+Al
