Question

mg+H2SO4=

Hg+hcl= k+h2o=

sn+h2o= Ag+h2o=

FeSO4+Sn=

AgNo3+Cu=

Hg(No3)2+fe=

Al2O3+ Zn=

Fe2o3+al=

Mno2+Zn=

Al+h2o=

Answer 1

Mg+H2SO4=MgSO4 + H2 ↑ 
Hg + HCl =  \\\\ 

2K + 2H2O = 2KOH + H2 ↑
Sn + 2H2O = SnO2 + 2H2  ↑

Ag + H2O = \\\\
FeSO4+Sn= \\\
2AgNo3 + Cu= Cu(NO3)2 + Ag
Hg(No3)2 + Fe= Fe(NO3)2 + Hg
Al2O3 + Zn= \\\
Fe2o3 + 2Al  = Al2O3 + 2Fe
Mno2 + Zn = \\\ 
2Al + 3H2O = 2Al(OH)3 + 3H2 ↑
