A bottle with a white crystalline substance is kept in the chemical laboratory. When heated, the substance completely decomposes with the formation of two gases and water. Under the action of potassium hydroxide, a light, colorless gas with a pungent odor is released, causing the litmus paper to turn blue. Write down the chemical formula and name of this substance. Make two equations of the reactions that were carried out in the process of its recognition.

One of the possible options is ammonium nitrate (some other ammonium salts, for example, carbonate, can be considered as an answer that satisfies the conditions).

NH4NO3 = N2 + O2 + H2O (temperature above 350 degrees Celsius)

NH4NO3 + KOH = KNO3 + H2O + NH3
