Carry out transformations: Mg – MgO – Mg (OH) ² – MgC1² – MgSO⁴

1) 2Mg + O2 = 2MgO (when magnesium interacts with oxygen, magnesium oxide is formed);

2) MgO + H2O = Mg (OH) 2 (when magnesium oxide interacts with water, magnesium hydroxide is formed);

3) Mg (OH) 2 + 2NH4Cl = MgCl2 + 2NH3 + 2H2O (when magnesium hydroxide interacts with ammonium chloride, magnesium chloride, ammonia and water are formed);

4) MgCl2 + H2SO4 = MgSO4 + 2HCl (when magnesium chloride reacts with sulfuric acid, magnesium sulfate and hydrochloric acid are formed).

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.
