Question

Нітратна кислота-магній нітрат-нітроген(ІІІ)оксид-нітратна кислота-Азот

Answer 1

2HNO3 + Mg(OH)2 = Mg(NO3)2  + 2H2O
2Mg(NO3)2 = 2MgO + 4NO2 +O2
4NO2 +O2 + 2H2O = 4 HNO3
12HNO3 + 5Mg = 5 Mg(NO3)2 + N2 + 6H20

Answer 2

I can understand and communicate in Ukrainian. Your message seems to be a request for a detailed explanation of a chemical reaction involving nitric acid, magnesium nitrate, nitrogen oxide, and nitrogen. Here is what I found:

Nitric acid (HNO3) is a strong acid and a powerful oxidizer that reacts with most metals, producing nitrates and hydrogen gas. For example, when nitric acid reacts with magnesium (Mg), it forms magnesium nitrate (Mg(NO3)2) and hydrogen gas (H2):

$$3HNO3 + Mg \rightarrow Mg(NO3)2 + H2 \uparrow$$

However, the hydrogen gas can also react with nitric acid, reducing it to nitrogen oxide (NO), which is a colorless gas with a sharp odor. The nitrogen oxide can then react with oxygen (O2) in the air to form nitrogen dioxide (NO2), which is a brown gas that contributes to air pollution and acid rain. The nitrogen dioxide can also react with water (H2O) to form more nitric acid, completing a cycle:

$$4HNO3 + H2 \rightarrow 4NO \uparrow + 4H2O$$ $$2NO + O2 \rightarrow 2NO2 \uparrow$$ $$3NO2 + H2O \rightarrow 2HNO3 + NO \uparrow$$

Nitrogen (N2) is a diatomic gas that makes up about 78% of the atmosphere. It is very stable and unreactive, and it does not react with nitric acid under normal conditions. However, under high temperature and pressure, nitrogen can react with hydrogen to form ammonia (NH3), which is an important industrial chemical and fertilizer. This reaction is known as the Haber-Bosch process, and it requires a catalyst such as iron:

$$N2 + 3H2 \rightleftharpoons 2NH3$$

Ammonia can also react with nitric acid to form ammonium nitrate (NH4NO3), which is another fertilizer and also an explosive compound. This reaction is exothermic, meaning it releases heat:

$$NH3 + HNO3 \rightarrow NH4NO3$$
