Answer 1

Substances and their reactions with diluted and concentrated sulfuric acid

Here is a breakdown of the substances you mentioned and their reactions with diluted and concentrated sulfuric acid:

1. Na2O (Sodium Oxide): - Reaction with diluted sulfuric acid: Sodium oxide reacts with diluted sulfuric acid to form sodium sulfate (Na2SO4). - Reaction with concentrated sulfuric acid: Sodium oxide reacts with concentrated sulfuric acid to form sodium hydrogen sulfate (NaHSO4).

2. Mg (Magnesium): - Reaction with diluted sulfuric acid: Magnesium reacts with diluted sulfuric acid to form magnesium sulfate (MgSO4) and hydrogen gas (H2). - Reaction with concentrated sulfuric acid: Magnesium reacts with concentrated sulfuric acid to form magnesium sulfate (MgSO4) and sulfur dioxide gas (SO2).

3. Hg (Mercury): - Reaction with diluted sulfuric acid: Mercury does not react with diluted sulfuric acid. - Reaction with concentrated sulfuric acid: Mercury does not react with concentrated sulfuric acid.

4. Cu(OH)2 (Copper Hydroxide): - Reaction with diluted sulfuric acid: Copper hydroxide reacts with diluted sulfuric acid to form copper sulfate (CuSO4) and water (H2O). - Reaction with concentrated sulfuric acid: Copper hydroxide reacts with concentrated sulfuric acid to form copper sulfate (CuSO4) and water (H2O).

5. FeCl2 (Iron(II) Chloride): - Reaction with diluted sulfuric acid: Iron(II) chloride reacts with diluted sulfuric acid to form iron(II) sulfate (FeSO4) and hydrogen chloride gas (HCl). - Reaction with concentrated sulfuric acid: Iron(II) chloride reacts with concentrated sulfuric acid to form iron(II) sulfate (FeSO4) and hydrogen chloride gas (HCl).

6. KCl (Potassium Chloride, in solid state): - Reaction with diluted sulfuric acid: Potassium chloride does not react with diluted sulfuric acid. - Reaction with concentrated sulfuric acid: Potassium chloride does not react with concentrated sulfuric acid.

7. S (Sulfur): - Reaction with diluted sulfuric acid: Sulfur does not react with diluted sulfuric acid. - Reaction with concentrated sulfuric acid: Sulfur reacts with concentrated sulfuric acid to form sulfur dioxide gas (SO2) and water (H2O).

8. P (Phosphorus): - Reaction with diluted sulfuric acid: Phosphorus does not react with diluted sulfuric acid. - Reaction with concentrated sulfuric acid: Phosphorus reacts with concentrated sulfuric acid to form phosphoric acid (H3PO4) and sulfur dioxide gas (SO2).

9. CO2 (Carbon Dioxide): - Reaction with diluted sulfuric acid: Carbon dioxide does not react with diluted sulfuric acid. - Reaction with concentrated sulfuric acid: Carbon dioxide does not react with concentrated sulfuric acid.

Please note that the reactions mentioned above are general representations and may vary depending on the specific conditions and concentrations of the substances involved.
