Zn+O2=?
.....+O2=CaO
Mg+HCl=MgCl2+?
KNO3=KNO2+.....
Fe+.....=FeCl3
......+NaOH=Mg(OH)2+NaCl
H2SO4+NaOH=....+...
MgCO=MgO+.......+......
ZnS+HCL=.....+H2S
NH3+.....=NH4Cl
Al+S=.......
AgNO+CaCl2=........+.........

Answer 1

2Zn + O2 =2ZnO

2Ca + O2= 2 CaO

Mg + 2HCl =Mg C l2 + H2

2KNO3 =2KNO2 + O2

2Fe +3 Cl2 =2 FeCl3

Mg Cl2 + 2NaOH= Mg( OH ) 2 +2 NaCl

H2SO4 +2NaOH=Na2 SO4 +2H2O

MgCO3 = Mg O + CO2

Zn S +2 HCl = ZnCl2 +H2S

NH3 + HCl = NH4 Cl

2Al +3 S = A l 2 S3

2Ag NO3 + CaCl2 =2Ag Cl + Ca( NO3 )2
