Question

Ba->BaO->-Ba(OH)2->BaSO4<--H2SO4<-SO3

Answer 1

1) 2Ba+O2=2BaO
2) BaO+H2O=Ba(OH)2
3) Ba(OH)2+H2SO4=BaSO4+2H2O
4) SO3+H2O=H2SO4
5) H2SO4+Ba(OH)2=BaSO4+2H2O

Answer 2

The given chemical reaction sequence involves the transformation of barium (Ba) into barium sulfate (BaSO4) through several intermediate steps. Let's break down the reaction sequence step by step:

1. Ba -> BaO: - In this step, barium (Ba) reacts with oxygen (O) to form barium oxide (BaO). - The reaction can be represented as: Ba + O2 -> BaO. - Barium oxide is a white solid compound.

2. BaO -> Ba(OH)2: - In the next step, barium oxide (BaO) reacts with water (H2O) to form barium hydroxide (Ba(OH)2). - The reaction can be represented as: BaO + H2O -> Ba(OH)2. - Barium hydroxide is a white crystalline compound that is soluble in water.

3. Ba(OH)2 -> BaSO4: - In this step, barium hydroxide (Ba(OH)2) reacts with sulfuric acid (H2SO4) to form barium sulfate (BaSO4). - The reaction can be represented as: Ba(OH)2 + H2SO4 -> BaSO4 + 2H2O. - Barium sulfate is a white solid compound that is insoluble in water.

4. H2SO4 <- SO3: - This step involves the reverse reaction, where sulfur trioxide (SO3) reacts with water (H2O) to form sulfuric acid (H2SO4). - The reaction can be represented as: SO3 + H2O -> H2SO4. - Sulfuric acid is a strong acid commonly used in various industrial processes.

It's important to note that these reactions are simplified representations and may not capture all the details and conditions required for the reactions to occur. The actual reaction conditions, such as temperature, pressure, and catalysts, can influence the reaction outcomes.
