# Write down the reaction equations: A) barium nitrate + iron (III) sulfate = barium sulfate + iron (III) nitrate

Write down the reaction equations: A) barium nitrate + iron (III) sulfate = barium sulfate + iron (III) nitrate B) iron (III) hydroxide = iron (III) oxide + water C) sulfuric acid + aluminum = aluminum sulfate + hydrogen D ) phosphorus oxide (V) + water = phosphoric acid E) calcium oxide + phosphorus oxide (V) = calcium phosphate E) aluminum hydroxide = aluminum oxide + water G) potassium nitrate = potassium nitrite + oxygen C) sulfuric acid + iron hydroxide ( III) = water + ferrous sulfate (III)

A) Reaction of barium nitrate and ferric sulfate, resulting in the formation of barium sulfate and ferric nitrate:

3 Ba (NO3) 2 + Fe2 (SO4) 3 = 3 BaSO4 + 2 Fe (NO3) 3

B) The reaction of decomposition of ferric hydroxide into iron oxide and water:

2 Fe (OH) 3 = Fe2O3 + 3 H2O

C) The reaction of sulfuric acid and aluminum, as a result of the reaction, aluminum sulfate is formed and hydrogen is released:

3 H2SO4 + 2 Al = Al2 (SO4) 3 + 3 H2

D) The reaction of pentavalent phosphorus oxide and vydy, as a result of the reaction, phosphoric acid is formed:

P2O5 + 3 H2O = 2 H3PO4

E) The reaction of calcium oxide and pentavalent phosphorus oxide, as a result of the reaction, calcium phosphate is formed:

3 CaO + P2O5 = Ca3 (PO4) 2

E) Reaction of decomposition of aluminum hydroxide to aluminum oxide and water:

2 Al (OH) 3 = Al2O3 + 3 H2O

G) The reaction of decomposition of potassium nitrate to potassium nitrite and oxygen is released.

2 KNO3 = 2 KNO2 + O2

H) Reaction of sulfuric acid and ferric hydroxide to water and ferric sulfate:

3 H2SO4 + 2 Fe (OH) 3 = 6 H2O + Fe2 (SO4) 3.
