Question

Cl2 - Hcl - NaCl - AgCl

Answer 1

Cl₂ + H₂ →hv(свет)→ 2HCl

2HCl + 2Na → 2NaCl + H₂↑

NaCl + AgNO₃ → AgCl↓ + NaNO₃

Answer 2

Ответ: Cl2 - HСl - NaCl - AgCl

Объяснение:

1) H2+ Cl2 =2 HСl

2) 2HСl+2Na= 2NaCl+H2↑

3)NaCl + AgNO3= AgCl↓+NaNO3

 

Answer 3

The chemical notation you've provided, "Cl2 - HCl - NaCl - AgCl," appears to represent a series of chemical compounds and reactions involving chlorine (Cl) and other elements. Let me explain each part:

1. Cl2 (Chlorine Gas): Cl2 represents chlorine gas, which consists of two chlorine atoms bonded together. Chlorine gas is a diatomic molecule and is a highly reactive and toxic substance.

2. HCl (Hydrochloric Acid): HCl represents hydrochloric acid, which is a strong acid. When chlorine gas (Cl2) reacts with water (H2O), it can form hydrochloric acid (HCl) through the following reaction:

   Cl2 + H2O → HCl + HCl

   This reaction produces two molecules of hydrochloric acid.

3. NaCl (Sodium Chloride): NaCl represents sodium chloride, which is commonly known as table salt. Sodium chloride is a compound composed of sodium (Na) and chlorine (Cl) ions. It's not a product of the previous reactions but is a common salt.

4. AgCl (Silver Chloride): AgCl represents silver chloride, which is a white solid compound formed when silver ions (Ag+) react with chloride ions (Cl-) in a solution. This reaction can occur when silver nitrate (AgNO3) is added to a solution containing chloride ions (Cl-):

   AgNO3 + Cl- → AgCl + NO3-

   The white precipitate formed is silver chloride (AgCl).

In summary, the series of reactions involve the conversion of chlorine gas (Cl2) into hydrochloric acid (HCl) when it reacts with water. Sodium chloride (NaCl) and silver chloride (AgCl) are not products of the initial reaction but are separate compounds that can be formed through other chemical reactions involving their respective elements.
