Question

So2 -> So3 -> H2So4 -> AI2(SO4)3 -> AI(OH)3 -> AI2O3

Answer 1

1) 2SO2+O2=2SO3

2)SO3+H2O=H2SO4

3) 3H2SO4+2Al(OH)3=Al2(SO4)3+6H2O

4) Al2(SO4)3+6KOH=2Al(OH)3+3K2SO4

5) Al(OH)3=Al2O3+H2O

Answer 2

The sequence you provided represents a series of chemical reactions involving sulfur dioxide (SO2) and aluminum (AI). Let's break down each step of the reaction:

1. SO2 (sulfur dioxide) reacts with oxygen (O2) to form SO3 (sulfur trioxide):

2 SO2 + O2 → 2 SO3

2. SO3 (sulfur trioxide) reacts with water (H2O) to form sulfuric acid (H2SO4):

SO3 + H2O → H2SO4

3. H2SO4 (sulfuric acid) reacts with aluminum oxide (AI2O3) to form aluminum sulfate (AI2(SO4)3):

H2SO4 + AI2O3 → AI2(SO4)3 + H2O

4. AI2(SO4)3 (aluminum sulfate) reacts with water (H2O) to form aluminum hydroxide (AI(OH)3):

AI2(SO4)3 + 6 H2O → 2 AI(OH)3 + 3 H2SO4

5. AI(OH)3 (aluminum hydroxide) reacts with heat to form aluminum oxide (AI2O3):

2 AI(OH)3 → AI2O3 + 3 H2O

So, the overall reaction starting from SO2 and ending with AI2O3 can be represented as:

2 SO2 + O2 → 2 SO3 → H2SO4 + AI2O3 → AI2(SO4)3 + 3 H2O → 2 AI(OH)3 → AI2O3 + 3 H2O
