K + O2 =

Ag + O2 =

K + H2 =

Ag + H2 =

K + N2 =

Ag + N2 =

K + Br2 =

Ag + F2 =

K + S =

Ag + S =

K + HCL =

Ag + H2S =

K + FeCO3 =

Ag + HgSO3 =

Answer 1

К+О2=КО2

Ag+O2=AgO2

KH2

AgH2

 

Answer 2

 4K+ O2 =K2O 

4Ag + O2 =Ag2O 

2K + H2 =2KH

2Ag + H2 =2AgH

2K + N2 = 2KN

2Ag + N2 =2AgN

2K + Br2 =2KBr

2Ag + F2 =2AgF

2K + S = K2S

2Ag + S = Ag2S

2K + 2HCL = 2KCL+ H2

2Ag + H2S = Ag2S+ H2

2K + FeCO3 =KC2O3+ Fe

2Ag + HgSO3 =Ag2SO3+ Hg
