Answer 1

А) NaNO3+ AgCl (осадок)
б) 2NH3 (сам допиши)
в) ZnCl2+H2 (выделение газа) 

Answer 2

a) NaCl + AgNO3

The reaction between sodium chloride (NaCl) and silver nitrate (AgNO3) results in the formation of silver chloride (AgCl) and sodium nitrate (NaNO3). This is a double displacement reaction, where the positive ions of the two compounds switch places.

The balanced chemical equation for this reaction is:

2NaCl + AgNO3 -> 2AgCl + NaNO3

In this reaction, the silver ions (Ag+) from silver nitrate combine with chloride ions (Cl-) from sodium chloride to form silver chloride, which is a white precipitate. The sodium ions (Na+) from sodium chloride combine with nitrate ions (NO3-) from silver nitrate to form sodium nitrate, which remains in solution.

b) N2 + H2

The reaction between nitrogen gas (N2) and hydrogen gas (H2) is a synthesis reaction that forms ammonia (NH3). This reaction is commonly known as the Haber process and is used to produce ammonia industrially.

The balanced chemical equation for this reaction is:

N2 + 3H2 -> 2NH3

In this reaction, the nitrogen molecules (N2) combine with hydrogen molecules (H2) to form ammonia (NH3). The reaction requires a catalyst and high temperature and pressure conditions for efficient conversion.

c) Zn + HCl

The reaction between zinc (Zn) and hydrochloric acid (HCl) is a single displacement reaction that produces zinc chloride (ZnCl2) and hydrogen gas (H2).

The balanced chemical equation for this reaction is:

Zn + 2HCl -> ZnCl2 + H2

In this reaction, the zinc atoms (Zn) react with the hydrogen ions (H+) from hydrochloric acid to form zinc chloride (ZnCl2). At the same time, hydrogen gas (H2) is released as a product.

It is important to note that the reaction between zinc and hydrochloric acid is highly exothermic, meaning it releases heat. Additionally, the reaction produces hydrogen gas, which is flammable and can form explosive mixtures with air. Therefore, this reaction should be conducted with caution.

Please exercise caution when performing any chemical reactions and ensure you have the necessary knowledge and safety precautions in place.
