Answer 2

Chain of Reactions: AlCl3 -> Al(OH)3 -> Al2O3

The chain of reactions you are referring to involves the transformation of aluminum chloride (AlCl3) into aluminum hydroxide (Al(OH)3), and then into aluminum oxide (Al2O3).

1. AlCl3 to Al(OH)3: - The first step in the chain is the reaction between aluminum chloride (AlCl3) and water (H2O), which produces aluminum hydroxide (Al(OH)3) and hydrochloric acid (HCl). - The balanced chemical equation for this reaction is: ``` AlCl3 + 3H2O -> Al(OH)3 + 3HCl ``` - This reaction is an example of a hydrolysis reaction, where water molecules break down the aluminum chloride compound into aluminum hydroxide and hydrochloric acid.

2. Al(OH)3 to Al2O3: - The second step in the chain is the dehydration of aluminum hydroxide (Al(OH)3) to form aluminum oxide (Al2O3). - When aluminum hydroxide is heated, it loses water molecules and undergoes a chemical change to become aluminum oxide. - The balanced chemical equation for this reaction is: ``` 2Al(OH)3 -> Al2O3 + 3H2O ``` - This reaction is an example of a dehydration reaction, where water molecules are removed from the compound to form a new substance.

So, the complete chain of reactions is as follows: ``` AlCl3 + 3H2O -> Al(OH)3 + 3HCl 2Al(OH)3 -> Al2O3 + 3H2O ```
