Question

Осуществить превращения: Магний → карбонат магния → оксид магния → нитрат магния → гидроксид магния

Answer 1

Mg + H2O + CO2 =MgCO3 + H2
MgCO3 = (t) MgO + CO2
MgO + 2HNO3 = Mg(NO3)2 + H2O
Mg(NO3)2 + 2NaOH = Mg(OH)2 + 2NaNO3

Answer 2

Chemical Transformations:

To carry out the series of transformations from magnesium to magnesium hydroxide, the following steps need to be followed:

1. Magnesium to Magnesium Carbonate: - The reaction to convert magnesium to magnesium carbonate involves the reaction of magnesium with carbonic acid or a carbonate salt. - The chemical equation for this reaction is: ``` Mg + H2CO3 -> MgCO3 + H2 ``` - Source:

2. Magnesium Carbonate to Magnesium Oxide: - The transformation from magnesium carbonate to magnesium oxide can be achieved through thermal decomposition. - The chemical equation for this reaction is: ``` MgCO3 -> MgO + CO2 ``` - Source: 3. Magnesium Oxide to Magnesium Nitrate: - To obtain magnesium nitrate from magnesium oxide, magnesium oxide needs to be reacted with nitric acid. - The chemical equation for this reaction is: ``` MgO + 2HNO3 -> Mg(NO3)2 + H2O ``` - Source: 4. Magnesium Nitrate to Magnesium Hydroxide: - The final step involves the reaction of magnesium nitrate with a base, such as sodium hydroxide, to yield magnesium hydroxide. - The chemical equation for this reaction is: ``` Mg(NO3)2 + 2NaOH -> Mg(OH)2 + 2NaNO3 ``` - Source: By following these steps, it is possible to achieve the transformation from magnesium to magnesium hydroxide.
