Question

Ba->BaO->BaSO4->BaCl2->AgCl->Cl2

Answer 1

Ba+O2=BaO

BaO+H2So4=BaSo4+H20

BaSo4+HCl=BaCl2+H2So4

BaCl2+Ag=AgCl+Ba(не уверенна)

AgCl=(при температуре и катализаторе)=Ag+Cl2

Answer 2

It seems like you've provided a sequence of chemical reactions involving various compounds and elements. Let's break down the sequence step by step:

1. Ba (Barium) -> BaO (Barium Oxide):

   • Barium (Ba) reacts with oxygen (O) to form barium oxide (BaO).

2. BaO (Barium Oxide) -> BaSO4 (Barium Sulfate):

   • Barium oxide (BaO) reacts with sulfuric acid (H2SO4) to form barium sulfate (BaSO4) and water (H2O).

3. BaSO4 (Barium Sulfate) -> BaCl2 (Barium Chloride):

   • Barium sulfate (BaSO4) is not directly involved in a reaction to form barium chloride (BaCl2). Typically, barium chloride is produced through the reaction of barium oxide (BaO) or barium carbonate (BaCO3) with hydrochloric acid (HCl).

4. BaCl2 (Barium Chloride) -> AgCl (Silver Chloride):

   • Barium chloride (BaCl2) reacts with silver nitrate (AgNO3) to form silver chloride (AgCl) and barium nitrate (Ba(NO3)2).

5. AgCl (Silver Chloride) -> Cl2 (Chlorine Gas):

   • Silver chloride (AgCl) can be decomposed into chlorine gas (Cl2) by heating it.

It's important to note that these reactions are simplified representations and may involve specific conditions and stoichiometries to proceed as described. Additionally, some steps in the sequence are not entirely accurate or are missing key details.
