Question

N2 -> NH3 -> NO -> NO2 -> HNO3 -> Ba(NO3)2?

Answer 1

NH3+O2=NO+H2O каталитическое окисление 2NO+O2=2NO2 4NO2+2H2O+O2=4HNO3 2HNO3+Ba(OH)2=Ba(NO3)2+2H2O

Answer 2

The series of chemical reactions you mentioned involves the conversion of nitrogen gas (N2) into barium nitrate (Ba(NO3)2). Let's break down each step:

1. N2 → NH3: This reaction represents the synthesis of ammonia (NH3) from nitrogen gas (N2). It is commonly known as the Haber process. This reaction is typically facilitated by a catalyst and occurs under high temperature and pressure.

2. NH3 → NO: The conversion of ammonia (NH3) to nitric oxide (NO) involves the oxidation of ammonia using a suitable catalyst. This reaction is known as the Ostwald process.

3. NO → NO2: Nitric oxide (NO) is further oxidized to nitrogen dioxide (NO2) in the presence of oxygen. This reaction can occur spontaneously or be catalyzed.

4. NO2 → HNO3: The nitrogen dioxide (NO2) is dissolved in water to form nitric acid (HNO3). This reaction is an example of the absorption of a gas in a liquid phase.

5. HNO3 → Ba(NO3)2: Finally, nitric acid (HNO3) reacts with barium hydroxide (Ba(OH)2) to form barium nitrate (Ba(NO3)2). The reaction can be represented as follows:

2 HNO3 + Ba(OH)2 → Ba(NO3)2 + 2 H2O

So, the overall series of reactions starting from N2 and leading to Ba(NO3)2 involves the synthesis of ammonia (NH3), followed by the conversion of ammonia to nitric oxide (NO), further oxidation to nitrogen dioxide (NO2), dissolution in water to form nitric acid (HNO3), and finally, the reaction between nitric acid and barium hydroxide to yield barium nitrate.
