Question

N2-NH3-NO-NO2-HNO3-NO2-HNO2-NO2-NANO3-NANO2

Answer 1

N2 + 3H2 = 2NH3
4NH3 + 5O2 = 4NO + 6H2O
2NO + O2 = 2NO2
4NO2 + O2 + 2H2O  = 4HNO3
4 HNO3 = 4 NO2+O2+2H2O
2NO2 + H2O = HNO2 + HNO3
2NaOH + 2NO2 = H2O + NaNO2 + NaNO 3
4NaNO3 = 4NaNO2+2O2 

Answer 2

N2 + 3H2 = 2NH3 
4NH3 + 5O2 =4NO + 6H2O 
2NO + O2 = 2NO2 
2NO2+H2O=HNO3+HNO2 
4HNO3+Cu=Cu(NO3)2+2NO2+2H2O 
NO + NO2 + H2O = 2HNO2
2HNO2=NO+NO2+ H2O
2NaOH + 2NO2 = NaNO2  + NaNO3 + H2O
2NaNO3=2NaNO2+O2 

Answer 3

The given sequence represents a series of chemical reactions involving nitrogen compounds. Here's a breakdown of each compound and the reactions involved:

1. N2: This represents a molecule of nitrogen gas, which is diatomic nitrogen.

2. NH3: This represents ammonia, which is a compound formed by the reaction of nitrogen gas (N2) and hydrogen gas (H2). The reaction is known as nitrogen fixation, and it is typically catalyzed by either high temperatures and pressures or certain enzymes present in nitrogen-fixing bacteria.

3. NO: This represents nitric oxide, which is formed by the reaction of ammonia (NH3) with oxygen (O2) in the presence of a catalyst. The reaction is known as the oxidation of ammonia.

4. NO2: This represents nitrogen dioxide, which is formed by the reaction of nitric oxide (NO) with oxygen (O2). This reaction is an example of a redox reaction where NO is oxidized to NO2.

5. HNO3: This represents nitric acid, which is formed by the reaction of nitrogen dioxide (NO2) with water (H2O). The reaction is known as the dissolution of nitrogen dioxide.

6. NO2: This represents nitrogen dioxide, which can be either produced by the reaction mentioned in step 4 or it may refer to the compound that was not consumed in step 5.

7. HNO2: This represents nitrous acid, which is formed by the reaction of nitrogen dioxide (NO2) with water (H2O). The reaction is known as the dissolution of nitrogen dioxide. Nitrous acid can also decompose to form nitric oxide (NO) and water (H2O) under specific conditions.

8. NO2: This represents nitrogen dioxide, which can be either produced by the reaction mentioned in step 7 or it may refer to the compound that was not consumed in step 7.

9. NANO3: This represents sodium nitrate, which is formed by the reaction of nitric acid (HNO3) with sodium hydroxide (NaOH). This reaction is an example of a neutralization reaction.

10. NANO2: This represents sodium nitrite, which is formed by the reaction of nitrous acid (HNO2) with sodium hydroxide (NaOH). This reaction is also an example of a neutralization reaction.

It's worth noting that the reactions mentioned are simplified representations, and there may be additional intermediate steps or side reactions involved in actual chemical processes.
