Question

? > N2 > ? > NO > ? > HNO3

Answer 1

4NH3 + 3O2 -> 2N2 + 6H2O
N2 + 3H2 -> 2NH3
 4NH3 + 5O2 -> 4NO + 6H2O
 2NO + O2 -> 2NO2
2NO2 + H2O -> HNO3 + HNO2

Answer 2

2NH3==>N2+3H2
N2+3H2==>2NH3
4NH3+5O2==>4NO+6H2O
2NO+O2==>2NO2
2NO2+H2O==>HNO3+HNO2

Answer 3

N2, NO, HNO3

N2, NO, and HNO3 are chemical compounds that are related to each other.

N2 refers to nitrogen gas, which is a diatomic molecule composed of two nitrogen atoms bonded together. It is the most abundant gas in Earth's atmosphere, making up about 78% of the air we breathe. Nitrogen gas is relatively inert and does not readily react with other substances under normal conditions.

NO refers to nitric oxide, which is a colorless gas with a sharp odor. It is a free radical and is produced in various biological processes, such as during the combustion of fossil fuels and in the human body as a signaling molecule. Nitric oxide plays important roles in regulating blood pressure, immune function, and neurotransmission.

HNO3 refers to nitric acid, which is a strong acid that is commonly used in laboratories and industries. It is a corrosive and highly reactive liquid that can dissolve many metals and forms salts called nitrates. Nitric acid is used in the production of fertilizers, explosives, and various other chemicals.

These compounds are all related to nitrogen and have different properties and uses. Nitrogen gas is an inert gas, while nitric oxide and nitric acid are reactive compounds with various applications in different fields.
