Write down the reaction equations according to the schemes: a) Potassium nitrate → Potassium nitrate

Write down the reaction equations according to the schemes: a) Potassium nitrate → Potassium nitrate → oxygen: b) Nitric oxide (V) + Water → Nitric acid: c) Sulfuric acid + iron hydroxide (lll) →? +? d) Molybdenum oxide + calcium →? +?

1. The decomposition of potassium nitrate takes place to produce potassium nitrite and oxygen.

2KNO3 = 2KNO2 + O2

2. The reaction of the compound between nitrogen oxide (V) and water is accompanied by the formation of nitric acid.

N2O5 + H2O = 2HNO3

3. The exchange reaction between sulfuric acid and iron (III) hydroxide proceeds with the formation of iron (III) sulfate and water.

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

4. The substitution reaction between molybdenum (VI) oxide and calcium proceeds with the formation of calcium oxide and molybdenum.

MoO3 + Ca = 3CaO + Mo
