Answer 2

N, NO, NO2, HNO3 are chemical formulas representing different compounds:

- N represents nitrogen, which is a chemical element with the atomic number 7. It is a colorless and odorless gas that makes up about 78% of the Earth's atmosphere. Nitrogen is an essential element for life and is used in various industrial processes.

- NO represents nitric oxide, which is a colorless gas with a chemical formula of NO. It is a free radical and an important signaling molecule in the body. Nitric oxide plays a role in various physiological processes, including vasodilation, neurotransmission, and immune response.

- NO2 represents nitrogen dioxide, which is a reddish-brown gas with a chemical formula of NO2. It is a highly reactive and toxic gas that is formed from the oxidation of nitric oxide in the atmosphere. Nitrogen dioxide is a major component of air pollution and can have harmful effects on human health.

- HNO3 represents nitric acid, which is a strong acid with a chemical formula of HNO3. It is a corrosive and highly reactive liquid that is used in various industrial processes, such as the production of fertilizers, explosives, and dyes. Nitric acid is also used in laboratory settings for chemical analysis and synthesis.
