I need to calculate the percent yields of the following unbalanced reactions, basically I need the stoichiometry:

1. Synthesis of [Co(NH3)6]Cl3 starting with CoCl2 hexahydrate and NH4Cl, 30% hydrogen peroxide and 'concentrated' HCl are used in the reaction.

2. Synthesis of [Co(NH3)5(NO2)]Cl2 starting with the o-bonded isomer and using ammonia, HCl, and heat.

3. Synthesis of [Co(NH3)5(ONO)]Cl2 starting with [Co(NH3)5(H2O)]Cl3, HCl, NaNO2, and ammonia.

4. Synthesis of [Co(NH3)5Cl]Cl2 starting with [Co(NH3)5(H2O)]Cl3 and heat.

5. Synthesis of [Co(NH3)x(CO3)]NO3 hemihydrate starting with Co(NO3)2 hexahydrate and using ammonia, ammonium carbonate, hydrogen peroxide, and water.

6. Synthesis of [Co(NH3)5(H2O)]Cl3 using Co(NO3)2 hexahydrate and ammonia, ammonium chloride, hydrogen peroxide, and HCl.
