Answer 1

Объяснение:

2KMnO4--> K2MnO4+MnO2+O2

2N2+5O2--> 2N2O5

4KClO3 --> 3KClO4 + KCl (400 °C);

KClO4 --> KCl + 2O2 (две последовательные реакции на третий пункт)

2CO+O2--> 2CO2

FeS+12HNO3--> Fe(NO3) 3+9NO2+ 5H2O

Н2О2 --> 2Н2О + O

2Fe+3Cl2--> 2FeCl3

2NaNO3--> 2NaNO2+O2

2PH3+4O2--> P2O5+3H2O

2C2H6+7O2--> 4CO2+ 6H2O

4Al+3O2--> 2Al2O3

2HI--> H2+I2

Chemical Reactions and Processes

1. Decomposition of potassium permanganate: The decomposition of potassium permanganate (KMnO4) can be achieved by heating it, resulting in the formation of manganese dioxide (MnO2) and oxygen gas (O2) [[1]].

2. Combination of nitrogen and oxygen to form nitrogen (V) oxide: When nitrogen gas (N2) and oxygen gas (O2) react, they can form nitrogen (V) oxide (NO2) [[2]].

3. Decomposition of potassium chlorate: Heating potassium chlorate (KClO3) can cause it to decompose into potassium chloride (KCl) and oxygen gas (O2) [[3]].

4. Oxidation of carbon (II) oxide: Carbon (II) oxide (CO) can be oxidized by reacting it with oxygen gas (O2), resulting in the formation of carbon dioxide (CO2) [[4]].

5. Oxidation of iron (II) sulfide: Iron (II) sulfide (FeS) can undergo oxidation when exposed to oxygen gas (O2), forming iron (III) oxide (Fe2O3) and sulfur dioxide (SO2) [[5]].

6. Decomposition of hydrogen peroxide: Hydrogen peroxide (H2O2) can decompose into water (H2O) and oxygen gas (O2) when heated or in the presence of a catalyst [[6]].

7. Oxidation of iron: Iron (Fe) can undergo oxidation when exposed to oxygen gas (O2), forming iron (III) oxide (Fe2O3), commonly known as rust [[7]].

8. Decomposition of sodium nitrate: Heating sodium nitrate (NaNO3) can cause it to decompose into sodium nitrite (NaNO2) and oxygen gas (O2) [[8]].

9. Oxidation of phosphorus hydride: Phosphorus hydride (PH3) can be oxidized by reacting it with oxygen gas (O2), resulting in the formation of phosphorus pentoxide (P2O5) and water (H2O) [[9]].

10. Combustion of ethane (C2H6): Ethane (C2H6) can undergo combustion when it reacts with oxygen gas (O2), producing carbon dioxide (CO2) and water vapor (H2O) as products [[10]].

11. Production of aluminum oxide from simple substances: Aluminum oxide (Al2O3) can be obtained by the reaction of aluminum metal (Al) with oxygen gas (O2), resulting in the formation of aluminum oxide [[11]].

12. Decomposition of hydrogen iodide into simple substances: Hydrogen iodide (HI) can be decomposed into hydrogen gas (H2) and iodine gas (I2) by heating or through the use of a suitable catalyst [[12]].
