Question

Ba ® BaCl2 ® Ba ® Ba(OH)2 ® BaSO4 ® Ba(OH)

Answer 1

Ответ:

Вот правильный ответ.

Answer 2

It looks like you've provided a sequence of chemical reactions involving the element barium (Ba) and various compounds. It seems like you want to discuss the reactions and products involved in this sequence. Let's go through each step:

1. Ba: This represents elemental barium, which is a metal.

2. BaCl2: This is barium chloride, a compound formed when barium reacts with chlorine. The chemical equation for this reaction is:

   Ba + Cl2 → BaCl2

3. Ba: This is again elemental barium.

4. Ba(OH)2: This is barium hydroxide, formed when barium reacts with water. The chemical equation is:

   Ba + 2H2O → Ba(OH)2 + H2

5. BaSO4: This is barium sulfate, which can be formed through a double displacement reaction between barium chloride and a sulfate compound. The chemical equation is:

   BaCl2 + Na2SO4 → BaSO4 + 2NaCl

6. Ba(OH)2: This is again barium hydroxide.

It seems like you've provided a sequence of reactions involving the transformation of elemental barium to various compounds and back to barium. If you have specific questions about these reactions or if you'd like to know more about their properties, uses, or anything else, feel free to ask!
