ПОМОГИТЕ!!!!! на пункты не скуплюсь)
1)Fe + 2HCl --> FeCl2 + H2
FeCl2 + 2NaOH --> Fe(OH)2 + 2NaCl
Fe(OH)2+H2SO4=FeSO4+2H2O
2)Al2(SO4)3 + 6NaOH = 2Al(OH)3 + 3Na2SO4
Al(OH)3 + 3HCl = AlCl3 + 3H2O
AlCl3 + 3AgNO3 = Al(NO3)3 + 3AgCl3
3) FeCl3+3NaOH=Fe(OH)3+3NaCl
2Fe(OH)3 = Fe2O3 + 3H2O
Fe2O3+3H2SO4=Fe2(SO4)3+3H2O
