помогите!!! пожалуйста!!!​

Answer 1

а)

3Fe+2O2=Fe3O4

S+O2=SO2

CH4=C+2H2

2P+5Br2=2PBr5

б)

2Al+3F2=2AlF3

N2+3H2=2NH3

6FeO+O2=2Fe3O4

2Fe+3Cl2=2FeCl3

в)

2H2O2=2H2O+O2

2Ca+O2=2CaO

2Na+Cl2=2NaCl

2BaO+O2=2BaO2

г)

4CuO=2Cu2O+O2

2SO2+O2=2SO3

2FeBr3=2FeBr2+Br2

CuCl2+Na2S=CuS+2NaCl

д)

2H2S+2O2=2SO2+2H2O

2C4H10+13O2=8CO2+10H2O

4Ag+2H2S+O2=2Ag2S+2H2O

е)

Zn+ 2HCl = ZnCl2 + H2

H2SO4+2KOH=K2SO4+2H2O

2CuOH = Cu2O + H2O
