Question

Mg → MgSO4 → MgO - Mg(NO3)2.​

Answer 1

Объяснение:

Mg→MgSO₄ →Mg(NO₃)₂ → MgO → MgCl₂ → Mg(OH)₂

Mg+H₂SO₄=MgSO₄+H₂↑

MgSO₄+Ba(NO₃)₂=Mg(NO₃)₂+BaSO₄↓

2Mg(NO₃)₂=2MgO+4NO₂↑+O₂↑

MgO +2HCI= MgCl₂+H₂O

MgCl₂+2NaOH= Mg(OH)₂↓+2NaCI

Answer 2

It looks like you're describing a series of chemical reactions involving magnesium (Mg) and various compounds. Let me break down the reactions step by step:

1. Mg → MgSO4: In this reaction, magnesium (Mg) reacts with sulfuric acid (H2SO4) to produce magnesium sulfate (MgSO4) and hydrogen gas (H2) as a byproduct. The balanced chemical equation for this reaction is:

   Mg + H2SO4 → MgSO4 + H2

2. MgSO4 → MgO: Here, magnesium sulfate (MgSO4) is subjected to a decomposition reaction, often by heating. This reaction breaks down magnesium sulfate into magnesium oxide (MgO), sulfur dioxide (SO2), and oxygen (O2). The balanced chemical equation is:

   2MgSO4 → 2MgO + 2SO2 + O2

3. MgO - Mg(NO3)2: This appears to be an incomplete or unclear reaction. It's not clear how magnesium oxide (MgO) would directly react with magnesium nitrate (Mg(NO3)2) without the presence of other reactants or conditions specified.

If you have a specific reaction or scenario in mind for the interaction between magnesium oxide (MgO) and magnesium nitrate (Mg(NO3)2), please provide more information, and I'd be happy to assist further.
