Complete the reaction equations and indicate their type Mg (OH) ₂⇒CaCO₃ + HCl⇒Ba + H₂O⇒P₂O₅ + H₂O⇒FeCl₂ + K₂CO₃⇒

Dissociation reaction of magnesium hydroxide to magnesium oxide and water. The molecular equation of the reaction is as follows:
Mg (OH) 2 = MgO + H2O

Chemical reaction and equation As a result of the reaction, a salt of calcium chloride and carbonic acid is formed, but since it is not stable, it decomposes in air into water and carbon dioxide. The molecular equation of the reaction is as follows:
CaCO3 + 2 HCl = CaCl2 + H2O + CO2

Chemical reaction and equation As a result of the reaction, barium hydroxide is formed and hydrogen is released. The molecular equation of the reaction is as follows:
Ba + 2 H2O = Ba (OH) 2 + H2

Chemical reaction and equation As a result of the reaction, phosphoric acid is formed. The molecular equation of the reaction is as follows:
P2O5 + 3 H2O = 2H3PO4

Chemical reaction and equation As a result of the reaction, a potassium chloride salt and an iron carbonate salt are formed. The molecular equation of the reaction is as follows:
FeCl2 + K2CO3 = 2KCl + FeCO3.
