Question

Осуществите превращения по следующей цепи MgSO4® Mg(OH)2 ® Mg(NO3)2 ® Mg Составьте уравнения химических реакций, выберите реакцию обмена в ионном виде.

Answer 1

MgSO4 + Ba(OH)2 = Mg(OH)2 + BaSO4

Mg(+2) + SO4(-2) + Ba(+2) + 2OH(-) = Mg(OH)2 + BaSO4.

Mg(OH)2 + 2AgNO3 = 2AgOH + Mg(NO3)2

Mg(NO3)2 + 2K = 2KNO3 + Mg

Answer 2

Chemical Reactions Transformation and Ion Exchange

To transform the given chemical compounds according to the provided chain, we'll start with the transformation of MgSO4 to Mg(OH)2, then to Mg(NO3)2, and finally to Mg.

1. MgSO4 to Mg(OH)2: - The chemical reaction for the transformation of MgSO4 to Mg(OH)2 involves a double displacement reaction. - The balanced chemical equation for this reaction is: ``` MgSO4 + 2NaOH → Mg(OH)2 + Na2SO4 ``` - This reaction results in the formation of Mg(OH)2 from MgSO4.

2. Mg(OH)2 to Mg(NO3)2: - The transformation of Mg(OH)2 to Mg(NO3)2 involves a reaction with nitric acid (HNO3). - The balanced chemical equation for this reaction is: ``` Mg(OH)2 + 2HNO3 → Mg(NO3)2 + 2H2O ``` - This reaction results in the formation of Mg(NO3)2 from Mg(OH)2.

3. Mg(NO3)2 to Mg: - The transformation of Mg(NO3)2 to Mg involves a decomposition reaction. - The balanced chemical equation for this reaction is: ``` 2Mg(NO3)2 → 2MgO + 4NO2 + O2 ``` - This reaction results in the formation of Mg from Mg(NO3)2 [[3]](https://ntpk2.ru/sites/default/files/documents/kim_estestvoznanie.pdf).

4. Ion Exchange Reaction: - An example of an ion exchange reaction involving the compounds provided is: ``` Ba(NO3)2 + Na2SO4 → BaSO4 + 2NaNO3 ``` - This reaction demonstrates the exchange of ions between the reactants, resulting in the formation of new compounds.

These chemical reactions illustrate the transformation of the given compounds according to the provided chain and an example of an ion exchange reaction involving similar compounds.
