Nitrogen reacted with hydrogen when heated on the catalyst. The resulting gas was absorbed with a nitric acid solution, evaporated to dryness, and the resulting crystalline substance was divided into two parts. The first was decomposed at a temperature of 190-240C, while only one gas and water vapor was formed. The second part was heated with concentrated sodium hydroxide solution. Write the equations for the described reactions.
N2 + 3H2 → 2NH3
NH3 + HNO3 → NH4NO3
NH4NO3 → N2O + 2H2O
NH4NO3 + NaOH → NaNO3 + NH3↑ + H2O
Remember: The process of learning a person lasts a lifetime. The value of the same knowledge for different people may be different, it is determined by their individual characteristics and needs. Therefore, knowledge is always needed at any age and position.
