Question

Cl2-hcl-nacl-na2so4-baso4

Answer 1

Ответ:

Cl2+H2=2HCl

HCl+NaOH=NaCl+H2O

2NaCl+H2SO4(к)=Na2SO4+2HCl↑

Na2SO4+BaCl2=BaSO4↓+2NaCl

Answer 2

It seems like you've listed a sequence of chemical compounds and reactions. Let me break it down for you:

1. Cl2 - This represents elemental chlorine, which exists as a diatomic molecule (Cl2). It is a highly reactive, greenish-yellow gas.

2. HCl - This is hydrochloric acid, which is a strong acid. It is a solution of hydrogen chloride (HCl) gas in water and is commonly used in various chemical processes.

3. NaCl - This is sodium chloride, commonly known as table salt. It is a compound formed by the combination of sodium (Na) and chlorine (Cl) ions.

4. Na2SO4 - This is sodium sulfate, a salt of sodium (Na) and sulfate (SO4) ions.

5. BaSO4 - This is barium sulfate, a white crystalline solid that is often used as a contrast agent in medical imaging, such as X-rays and CT scans.

Without more context or specific information, it's unclear how these compounds are related or what reaction or process you are referring to. If you have a specific question or need more information about a particular aspect of these compounds or their interactions, please provide additional details, and I'd be happy to help.
