Question

Mg-MgO-MgCl²-Mg(OH) ²-MgOC-CO²-Na²CO³-Na²SO⁴-BaSO⁴​

Answer 1

Ответ:

Объяснение:

1) 2Mg + O2 = 2MgO

MgO + 2HCl = MgCl2 + H2O

MgCl2 + 2NaOH = Mg(OH)2 + 2NaCl

Mg(OH)2 = MgO+ H2O

2) C + O2 = CO2

CO2 + 2NaOH = Na2CO3 + H2O

Na2CO3 + H2SO4 = Na2SO4 + CO2 + H2O

Na2SO4 + BaCl2 = BaSO4 + 2NaCl

Answer 2

The sequence you provided appears to be a list of chemical compounds and their possible reactions. Let's analyze each component:

1. Mg (Magnesium): This is a chemical element, a metal with the symbol Mg.

2. MgO (Magnesium Oxide): This is a compound formed by the combination of magnesium and oxygen, represented as MgO. It is commonly known as magnesium oxide.

3. MgCl² (Magnesium Chloride): This is a compound formed by the combination of magnesium and chlorine, represented as MgCl². It is commonly known as magnesium chloride.

4. Mg(OH)² (Magnesium Hydroxide): This is a compound formed by the combination of magnesium and hydroxide ions, represented as Mg(OH)². It is commonly known as magnesium hydroxide.

5. MgOC (Magnesium Oxycarbide): This compound does not appear to be a well-known or common compound. It might be a hypothetical or less-studied compound.

6. CO² (Carbon Dioxide): This is a compound formed by the combination of one carbon atom and two oxygen atoms, represented as CO². It is commonly known as carbon dioxide.

7. Na²CO³ (Sodium Carbonate): This is a compound formed by the combination of sodium and carbonate ions, represented as Na²CO³. It is commonly known as sodium carbonate or soda ash.

8. Na²SO⁴ (Sodium Sulfate): This is a compound formed by the combination of sodium and sulfate ions, represented as Na²SO⁴. It is commonly known as sodium sulfate.

9. BaSO⁴​ (Barium Sulfate): This is a compound formed by the combination of barium and sulfate ions, represented as BaSO⁴​. It is commonly known as barium sulfate.

It seems like you have listed a mix of elements, oxides, chlorides, hydroxides, and carbonates, along with some common inorganic compounds. There is also one compound (MgOC) that is not widely recognized or known.

If you have any specific questions or need further information about any of these compounds or their reactions, feel free to ask!
