Question

ХИМИЯ 7 8 СУРАК КОМЕК КЕРЕК

Answer 1

7)

2SO2+O2-->2SO3

2Fe+3CL2-->2FeCL3

N2+3H2-->2NH3

Zn+2HCL-->ZnCL2+H2

8)

2Mg+O2-->2MgO

2Na+2H2O-->2NaOH+H2

Answer 2

7.
2 SO2 + O2 (kat. V2O5) = 2 SO3 ↑
2 Fe + 3 Cl2 = 2 FeCl3
N2 + 3 H2 = 2 NH3 ↑
Zn + 2 HCl = ZnCl2 + H2↑
8.
2 Mg + O2 = 2 MgO
2 Na + 2 H2O = 2 NaOH + H2↑
