In the scheme, write down the equations Mg – MgO – MgSO4 – Mg (OH) 2 – MgCL2

1) 2Mg + O2 = 2MgO, – to convert magnesium to magnesium oxide, you need to react with oxygen.

2) MgO + FeSO4 = MgSO4 + FeO, – in order to convert magnesium oxide into magnesium sulfate, you need to react with iron sulfate or other active / inactive metal, which occupies a position in the row of metal activity to the right than magnesium itself. Then magnesium, as a more active metal, will be able to displace the less active metal from the salt.

3) MgSO4 + 2NaOH = Na2SO4 + Mg (OH) 2, – in order to convert magnesium sulfate into magnesium hydroxide, it is necessary to react with an alkali so that the metal underlying the alkali can displace magnesium from the salt.

4) Mg (OH) 2 + CuCl2 = MgCl2 + Cu (OH) 2, – in order to convert magnesium hydroxide into magnesium chloride, you need to react with copper chloride or other active / inactive metal, which occupies a position in the row of metal activity to the right than itself magnesium. Then magnesium, as a more active metal, will be able to displace the less active metal from the salt.



One of the components of a person's success in our time is receiving modern high-quality education, mastering the knowledge, skills and abilities necessary for life in society. A person today needs to study almost all his life, mastering everything new and new, acquiring the necessary professional qualities.
