Question

N2-NO- NO2- HNO2-HNO3-Ca(NO3)2

Answer 1

Ответ:

Объяснение:

N2+O2 = 2NO

2NO+O2 = 2NO2  

2NO2+H2O = HNO3+HNO2

Ca(OH)2+2HNO3 -> Ca(NO3)2+2H2O

Answer 2

It seems like you've provided a list of chemical species, which includes some nitrogen-containing compounds. Let me provide you with some information about each of these species:

1. N2: This represents molecular nitrogen, which is the diatomic molecule found abundantly in Earth's atmosphere. It is relatively inert under normal conditions.

2. NO: Nitric oxide is a colorless gas with the chemical formula NO. It plays a significant role in various biological processes and is involved in the regulation of blood vessel dilation and neurotransmission.

3. NO2: Nitrogen dioxide is a reddish-brown gas with the chemical formula NO2. It is an important air pollutant and a precursor to the formation of ozone and acid rain.

4. HNO2: Nitrous acid, with the chemical formula HNO2, is a weak acid. It is a precursor to nitric acid and is often used in chemical reactions.

5. HNO3: Nitric acid, with the chemical formula HNO3, is a strong acid. It is widely used in the production of fertilizers, explosives, and other chemicals.

6. Ca(NO3)2: Calcium nitrate is a chemical compound composed of calcium ions (Ca²⁺) and nitrate ions (NO3⁻). It is often used as a fertilizer, as it provides both calcium and nitrogen to plants.

If you have any specific questions about these compounds or need more information about their properties or uses, please feel free to ask.
