Question

С какими из веществ будет реагировать соляная кислота NA2O H2CO3 FE H2O O2 MG(OH)2 SO3

Answer 1

1. 2HCl+Na2O=2NaCl=H2O
2. 2HCl+Fe=FeCl2+H2
3. 2HCl+Mg(OH)2=MgCl2+2H20
Кислоты не взаимодействуют с другими кислотами, водой и кислотными оксидами.

Answer 2

Reactions of Sulfuric Acid (H2SO4) with the Given Substances

Sulfuric acid (H2SO4) can react with various substances. Here are the reactions of sulfuric acid with the given substances:

1. Na2O (Sodium Oxide): - Sulfuric acid reacts with sodium oxide to form sodium sulfate. - The balanced chemical equation for the reaction is: ``` Na2O + H2SO4 -> Na2SO4 + H2O ```

2. H2CO3 (Carbonic Acid): - Sulfuric acid reacts with carbonic acid to form water and carbon dioxide. - The balanced chemical equation for the reaction is: ``` H2CO3 + H2SO4 -> CO2 + 2H2O + H2SO4 ```

3. Fe (Iron): - Sulfuric acid reacts with iron to form iron sulfate and hydrogen gas. - The balanced chemical equation for the reaction is: ``` Fe + H2SO4 -> FeSO4 + H2 ```

4. H2O (Water): - Sulfuric acid does not react with water under normal conditions.

5. O2 (Oxygen): - Sulfuric acid does not react with oxygen gas under normal conditions.

6. Mg(OH)2 (Magnesium Hydroxide): - Sulfuric acid reacts with magnesium hydroxide to form magnesium sulfate and water. - The balanced chemical equation for the reaction is: ``` Mg(OH)2 + H2SO4 -> MgSO4 + 2H2O ```

7. SO3 (Sulfur Trioxide): - Sulfuric acid reacts with sulfur trioxide to form oleum (a solution of sulfuric acid and sulfur trioxide). - The balanced chemical equation for the reaction is: ``` SO3 + H2SO4 -> H2S2O7 ```

Conclusion

Sulfuric acid can react with sodium oxide, carbonic acid, iron, magnesium hydroxide, and sulfur trioxide to form various products as described above.
