Answer 1

2KOH + N2O5 -> 2KNO3 + H2O
2 KOH + ZnO + Н2О-> K2[Zn(OH)4]
2KOH + H2SO4 -> K2SO4 + 2H2O
2 KOH + Mg(NO3)2 -> 2KNO3 + Mg(OH)2

Answer 2

Reactivity of Potassium Hydroxide with Listed Substances

Potassium hydroxide (KOH) is a strong base and will react with various substances. Let's examine its reactivity with the listed substances:

1. Oxide of Magnesium (MgO): - Potassium hydroxide will react with magnesium oxide to form magnesium hydroxide. - The balanced chemical equation for the reaction is: ``` MgO + 2KOH → Mg(OH)2 + K2O ```

2. Nitric Oxide (V) (NO): - Potassium hydroxide will react with nitric oxide to form potassium nitrate and water. - The balanced chemical equation for the reaction is: ``` 3NO + 6KOH → 2KNO3 + 3H2O ```

3. Zinc Oxide (ZnO): - Potassium hydroxide will react with zinc oxide to form zincate ion and water. - The balanced chemical equation for the reaction is: ``` ZnO + 2KOH → K2ZnO2 + H2O ```

4. Sulfuric Acid (H2SO4): - Potassium hydroxide will react with sulfuric acid to form potassium sulfate and water. - The balanced chemical equation for the reaction is: ``` H2SO4 + 2KOH → K2SO4 + 2H2O ```

5. Barium Carbonate (BaCO3): - Potassium hydroxide will react with barium carbonate to form barium hydroxide and potassium carbonate. - The balanced chemical equation for the reaction is: ``` BaCO3 + 2KOH → Ba(OH)2 + K2CO3 ```

6. Magnesium Nitrate (Mg(NO3)2): - Potassium hydroxide will react with magnesium nitrate to form magnesium hydroxide and potassium nitrate. - The balanced chemical equation for the reaction is: ``` Mg(NO3)2 + 2KOH → Mg(OH)2 + 2KNO3 ```

Conclusion

Potassium hydroxide exhibits various reactions with the listed substances, forming different products based on the specific chemical properties of each substance.
