Answer 2

Răspuns:

Explicație:

2H2 + O2 =2H2O

H2 + S=H2S

H2 + Cl2 =2HCl

H2 + F2= 2 HF

2Mg + O2=2MgO

Mg + S=MgS

Mg +Cl2=MgCl2

Mg + F2= MgF2

2Ca +O2 =2CaO

Ca + S=CaS

Ca +Cl2 =CaCl2

Ca +F2 =CaF2

4K + O2=2K2O

2K + S=K2S

2K + Cl2=2KCl

2K + F2=2KF

4Al +3O2 =2Al2O3

2Al +3 S=Al2S3

2Al + 3Cl2 =2AlCl3

2Al +3F2=2AlF3

4Li + O2=2Li2O

2Li +S= Li2S

2Li + Cl2=2LiCl

2Li + F2=2Li F

2Zn +O2=2ZnO

Zn +S=ZnS

Zn +Cl2=ZnCl2

Zn + F2=ZnF2
