Question

Осуществить цепочку превращений:
1) H2 -> H2S -> SO2 -> SO3 -> H2SO4
2) CuO -> H2O -> H2 -> HCL -> AgCl
3) N2 -> NH3 -> N2 -> NO -> NO2

Answer 1

H2+S=H2S
2H2S+3O2=2SO2+2H2O
2SO2+O2=2SO3
SO3+H2O=H2SO4

CuO+H2=Cu+H2O
2H2O=2H2+O2
H2+Cl2=2HCl
HCL+AgNO3=AgCl+HNO3

N2+3H2=2NH3
4NH3+3O2=2N2+6H2O
N2+O2=2NO
2NO+O2=2NO2
