Make up the formulas of the reaction products: a) CaO + HNO3 = Cu (OH) 2 + HCL = Fe2O3 + SO3 = P2O5 + KON = NaOH + H2SO4 = b) SO3 + H2O = SO3 + KON = Na2O + H2SO4 = Na2 + CO2 = Na2O + H2O =

А)

The reaction between calcium oxide and nitric acid produces calcium nitrate and water.

CaO + 2HNO3 = Ca (NO3) 2 + H2O.

As a result of the reaction between copper (II) hydroxide and hydrochloric acid, copper (II) chloride and water are formed.

Cu (OH) 2 + 2HCl = CuCl2 + 2H2O.

As a result of the reaction between iron (III) oxide and sulfur (IV) oxide, iron (III) sulfate is formed.

Fe2O3 + 3SO3 = Fe2 (SO4) 3. P2O5 + 6KOH = 2 K3PO4 + 3H2O (potassium phosphate and water).

2NaOH + H2SO4 = Na2SO4 + 2H2O (sodium sulfate and water).

B)

As a result of the reaction between water and sulfur (IV) oxide, sulfuric acid is formed /

SO3 + H2O = H2SO4.

SO3 + 2KOH = K2SO4 + H2O (potassium sulfate and water).

Na2O + H2SO4 = Na2SO4 + H2O (sodium sulfate and water).

As a result of the reaction between sodium and carbon oxides, sodium carbonate is formed.

Na2O + CO2 = Na2CO3.

Na2O + H2O = 2NaOH (sodium hydroxide).
