Question

uzupełnij współczynniki stechiometryczne w rownaniach reakcji:
PbO+H2- PbO+H2O
PbO2+C- Pb+CO2
PbO2+H2- Pb+H2O
CO+O2- CO2
N2+O2- 2NO
ZnO+ Al- Al2O3+Zn
Na+HCL- NaCL+H2
H2+O2- H2O
N2+O2- N2O3

Answer 1

PbO+H2--->Pb+H2O

PbO2+C--->Pb+CO2

PbO2+2H2--->Pb+2H2O

2CO+O2--->2CO2

N2+O2--->2NO

3ZnO+ 2Al--->Al2O3+3Zn

2Na+2HCl--->2NaCl+H2

2H2+O2--->2H2O

2N2+3O2--->2N2O3
