Na + O2 = CaO + H2 = FeO + H2 = Zn + HCl = Na + HCl = Al2O3 + H2 = Fe2O3 + H2 =

Question

Na + O2 =

CaO + H2 =

FeO + H2 =

Zn + HCl =

Na + HCl =

Al2O3 + H2 =

Fe2O3 + H2 =

Answer 1

2Na+O2=Na2O2 пероксид натрия
CaO+H2=Ca+H2O
FeO+H2=Fe+H2O
Zn+2HCl=ZnCl2+H2
2Na+2HCl=2NaCl+H2
Al2O3+3H2=2Al+3H2O
Fe2O3+3H2=2Fe+3H2O
