Question

Al → Al2O3 → Al(OH)3 → AlCl3

Answer 1

4Al + 3O2 = 2Al2O3

Al2O3 + 3H2O = 2Al(OH)3

Al(OH)3 + 3HCl = AlCl3 + 3H2O

Answer 2

It seems like you've provided a sequence of chemical reactions involving aluminum (Al) and various compounds formed from it. This sequence represents the transformation of aluminum into different compounds through a series of reactions. Let's break down the reactions step by step:

1. Aluminum (Al) → Aluminum Oxide (Al2O3): This reaction involves the oxidation of aluminum to form aluminum oxide, commonly known as alumina. The chemical equation for this reaction is:

   4 Al + 3 O2 → 2 Al2O3

2. Aluminum Oxide (Al2O3) → Aluminum Hydroxide (Al(OH)3): This reaction involves the hydrolysis of aluminum oxide to form aluminum hydroxide, which is a compound often found as a gelatinous precipitate. The chemical equation for this reaction is not straightforward and requires the presence of water to proceed.

3. Aluminum Hydroxide (Al(OH)3) → Aluminum Chloride (AlCl3): This reaction involves the replacement of hydroxide ions in aluminum hydroxide with chloride ions to form aluminum chloride. The chemical equation for this reaction is:

   Al(OH)3 + 3 HCl → AlCl3 + 3 H2O

Each step in this sequence represents a chemical transformation that involves changes in the oxidation states and the composition of the elements and compounds. These reactions are commonly encountered in various industrial processes and chemical reactions involving aluminum.
