Question

H2S→SO2→MgSO3→MgSO4→Mg(NO3)2​

Answer 1

Объяснение:

1 2H2S+3O=2SO2+2H2O

2 SO2+MgO=MgSO3

3 MgSO3 + H2SO4= MgSO4+ H2O +SO2

4 MgSO4 + 2HNO3 = Mg(No3)2 +H2SO4

Answer 2

H₂S + O₂   →   SO₂ + H₂O

MgO + SO₂   →   MgSO₃

2 MgSO₃ + O₂   →   2 MgSO₄

MgSO₄ + 2 NaNO₃   →   Mg(NO₃)₂ + Na₂SO₄

Answer 3

It looks like you've provided a series of chemical reactions involving various compounds. Let's break down each step of the reaction sequence:

1. H2S → SO2: This reaction represents the oxidation of hydrogen sulfide (H2S) gas to sulfur dioxide (SO2) gas.

2. SO2 → MgSO3: This reaction involves the reaction of sulfur dioxide (SO2) with magnesium oxide (MgO) to form magnesium sulfite (MgSO3).

3. MgSO3 → MgSO4: This reaction signifies the oxidation of magnesium sulfite (MgSO3) to magnesium sulfate (MgSO4), typically through exposure to air or an oxidizing agent.

4. MgSO4 → Mg(NO3)2: This step involves the reaction of magnesium sulfate (MgSO4) with nitric acid (HNO3) to produce magnesium nitrate (Mg(NO3)2) and other products.

Please note that the reactions you've provided involve several chemical transformations. If you have specific conditions or concentrations for these reactions, they might proceed differently. Additionally, chemical reactions are subject to certain physical and chemical constraints, so some reactions may require specific catalysts, temperatures, or other factors to proceed effectively. If you have any specific questions about these reactions or their applications, feel free to ask!
