Complete the molecular equations of possible reactions, write down the corresponding ionic equations: a) P2o5 + NaOH b) Fe (OH) 2 + HNO3 (g) c) (NH4) 2SO4 + KON g) Ca (OH) 2 (g) + CO2

a) The reaction takes place between substances such as pentavalent phosphorus oxide. As a result of the reaction, substances are formed: water and sodium orthophosphate. The molecular equation of the reaction can be written as follows:

P2O5 + 6 NaOH = 2 Na3PO4 + 3 H2O

b) The reaction takes place between substances such as iron hydroxide and nitric acid. As a result of the reaction, substances are formed: iron nitrate salt and water. The molecular equation of the reaction can be written as follows:

Fe (OH) 2 + HNO3 = Fe (NO3) 2 + 2 H2O

c) The reaction takes place between substances such as ammonium sulfate and calcium hydroxide. As a result of the reaction, substances are formed: potassium sulfate salt, water and ammonia. The molecular equation of the reaction can be written as follows:

(NH4) 2SO4 + KOH = К2SO4 + 2 NH3 ↑ + 2 H2O

d) The reaction takes place between substances such as calcium hydroxide and carbon dioxide. As a result of the reaction, a substance is formed: calcium carbonate and water is released. The molecular equation of the reaction can be written as follows:

Ca (OH) 2 + CO2 = CaCO3 + H2O.
