Chemical Reactions and Balancing

Sure, let's identify the reactions of decomposition and balance the chemical equations.

1. Fe + HCl -> H2 + FeCl2 - Reaction: FeCl2 - Balanced Equation: ``` Fe + 2HCl -> H2 + FeCl2 ```

2. CO2 + Mg -> MgO + C - Reaction: CO2, MgO - Balanced Equation: ``` CO2 + 2Mg -> 2MgO + C ```

3. Fe(OH)3 -> Fe2O3 + H2O - Reaction: Fe2O3, H2O - Balanced Equation: ``` 2Fe(OH)3 -> Fe2O3 + 3H2O ```

4. KMnO4 -> K2MnO2 + MnO2 + O2 - Reaction: K2MnO2, MnO2, O2 - Balanced Equation: ``` 2KMnO4 -> K2MnO2 + MnO2 + O2 ```

5. KClO3 -> KCl + O2 - Reaction: KCl, O2 - Balanced Equation: ``` 2KClO3 -> 2KCl + 3O2 ```

6. Al2S3 + H2O -> Al(OH)3 + H2S - Reaction: Al(OH)3, H2S - Balanced Equation: ``` Al2S3 + 6H2O -> 2Al(OH)3 + 3H2S ```

7. Na2O + H2O -> NaOH - Reaction: NaOH - Balanced Equation: ``` Na2O + H2O -> 2NaOH ```

8. AgNO3 -> Ag + NO2 + O2 - Reaction: Ag, NO2, O2 - Balanced Equation: ``` 2AgNO3 -> 2Ag + 2NO2 + O2 ```

9. Li + H2O -> LiOH + H2 - Reaction: LiOH, H2 - Balanced Equation: ``` 2Li + 2H2O -> 2LiOH + H2 ```

10. HgO -> Hg + O2 - Reaction: Hg, O2 - Balanced Equation: ``` 2HgO -> 2Hg + O2 ```
