correct mole ration for the following

silver to copper(II) nitrate in the reaction: Cu + AgNO3 ==> Cu(NO3)2 + Ag 

 oxygen to potassium chlorate in the reaction: KClO3 ==> KCl + O2 

ammonia to hydrogen in the reaction: N2 + H2 ==> NH3

The first step to these problems would be to balance the reaction:

Cu + 2AgNO3 ---> Cu(NO3)2 + 2Ag

2KClO3 ---> 2KCl + 3O2

3N2 + 3H2 ---> 2NH3

the mole ratios would be:

silver to copper (II) nitrate- 2:1

oxygen to potassium chlorate- 3:2

ammonia to hydrogen- 2:3
