Question

C⇒CO⇒CO2⇒Na2CO3⇒Na2SO4; Mg⇒MgO⇒Mg(OH)2⇒MgSO4⇒Mg(NO3)2.

Answer 1

Ответ:

C→CO→CO2→Na2CO3→Na2SO4

2 C+O2 → 2 CO

2 CO → CO2+C

Na2O+CO2 → Na2CO3

Na2CO3+H2SO4 → Na2SO4+CO2+H2O

Mg→MgO→Mg(OH)2→MgSO4→Mg(NO3)2

2 Mg+O2 → 2 MgO

MgO+H2O → Mg(OH)2

Mg(OH)2+H2SO4 → MgSO4+2 H2O

MgSO4+2 NaNO3 → Mg(NO3)2+Na2SO4

Answer 2

It seems like you've provided a series of chemical reactions involving different compounds and elements. Let me break down these reactions step by step:

1. C → CO: This reaction represents the conversion of carbon (C) into carbon monoxide (CO).

2. CO → CO2: This reaction represents the oxidation of carbon monoxide (CO) into carbon dioxide (CO2).

3. CO2 → Na2CO3: This reaction indicates the reaction of carbon dioxide (CO2) with a source of sodium (Na) to form sodium carbonate (Na2CO3).

4. Na2CO3 → Na2SO4: This reaction shows the conversion of sodium carbonate (Na2CO3) into sodium sulfate (Na2SO4). This might involve the reaction with sulfuric acid or another sulfate source.

5. Mg → MgO: This reaction represents the conversion of magnesium (Mg) into magnesium oxide (MgO), typically through oxidation.

6. MgO → Mg(OH)2: This reaction indicates the reaction of magnesium oxide (MgO) with water (H2O) to form magnesium hydroxide (Mg(OH)2).

7. Mg(OH)2 → MgSO4: This reaction represents the conversion of magnesium hydroxide (Mg(OH)2) into magnesium sulfate (MgSO4), typically through a reaction with sulfuric acid or another sulfate source.

8. MgSO4 → Mg(NO3)2: This reaction shows the conversion of magnesium sulfate (MgSO4) into magnesium nitrate (Mg(NO3)2), typically through a reaction with nitric acid or another nitrate source.

These reactions involve various chemical transformations of elements and compounds. If you have specific questions or need more details about any of these reactions, please feel free to ask.
