СРОЧНО!!!!!20 баллов!!!!Расставьте коэффициенты в схемах и укажите типы химических реакций:

1) Fe2O3 + HCl -FeCl3 + H2O
2) NO + O2 -NO2

3) N2 + O2 = NO
4) CaCO3 = CaO + CO2

5) Al2O3 + H2SO4 -Al2(SO4)3 + H2O
6) H2 + Cl2 -HCl

7) Li + O2 -Li2O
8) Fe2O3 + Al -Al2O3 + Fe

9) CuO + HCl = CuCl2 + H2O

10) NH3 = N2 + H2

11) Fe2O3 + H2= Fe + H2O

12) Zn + HCl = ZnCl2 + H2
