Answer 2

They are as follows :-

. 2Fe + 3H2o ---> Fe2o3 +3H2

.CH4 +2O2 ---->Co2 +2H2O

.Zn +AgNo3 ---->ZnNO3 +Ag

.Pb +CuCl2 ----> PbCl2 +Cu

.Zn + 2AgNO3 ----> Zn(NO3)2 + 2Ag

.4Fe + 6H2o -----> 2Fe2O3 + 6H2

.2KMnO4 +3H2So4 ----->K2So4 + 2MnSo4 + 3H2O +5O

.2H2 +O2 ----> 2H2O

.2Mg +CO2 ------> 2MgO +C

.Cl2 + H2 ----->2HCl

.2Al + Fe2O3 ---> Al2O3 +Fe

.2Na + 2H2O -----> 2NaOH + H2

.CS2 +3O2 ------> CO2 + 2SO2

.2H2O ----------> 2H2 + O2

.2SO2 + O2 ------> 2SO3

.2Mg + O2 ------> 2MgO

.C + O2 --------> CO2

.N2 + 3H2 --------> 2NH3

.2H2S +SO2 -------> 2H2O + 3S

.2NaI + Cl2 --------> 2Nacl + I2
