Question

1. NaOH+HCl --> Na Cl + H2O
2. Zn+ H2SO4 --> ZnSO4 + H2
3.Cu(OH)2 -> CuO + H2O
4.Fe+H2O -> Fe3O4 + H2
5.P+O2-->P2O5
6.NO2 + O2 + H2O ->HNO3
Egaleaza ecuatiile. Indica oxizii si tipul lor

Answer 1

1)2NaOH+2HCl=>2NaCl+2H2O
2)Zn+H2SO4=>H2gaz+ZnCl2
3)Cu(OH)2=>2Cuo+2H2O
4)3Fe+4H2O=>Fe3O4+4H2gaz
5)4P+5O2=>2P2O5
6)2NO2+O2+H2O=>2HNO3
