Question

Al>NaAlo2>Al(OH)3>Al2(So4)3>AlCl3

Answer 1

Ответ:

Объяснение:

2Al + 2NaOH + 2H2O ->2NaAlO2 +3H2↑

NaAlO2 + 2H2O(гор) -> Al(OH)3↓ + NaOH

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

Al2(SO4)3 + 3BaCl2 = 3BaSO4↓ + 2AlCl3

Answer 2

The sequence you provided seems to represent a series of chemical reactions involving aluminum compounds. Here's a breakdown of each compound:

1. Al: This represents aluminum in its elemental form, which is the metal itself.

2. NaAlO2: This compound is known as sodium aluminate, which is formed by the reaction between aluminum oxide (Al2O3) and sodium hydroxide (NaOH). It is a white, crystalline solid.

3. Al(OH)3: This compound is aluminum hydroxide, which can be obtained by treating sodium aluminate with an acid, typically sulfuric acid (H2SO4). Aluminum hydroxide is a white, gelatinous precipitate.

4. Al2(SO4)3: This compound is aluminum sulfate, which is formed by the reaction between aluminum hydroxide and sulfuric acid. It is a white crystalline solid commonly used in water treatment and as a mordant in dyeing.

5. AlCl3: This compound is aluminum chloride, which can be prepared by the reaction between aluminum metal and chlorine gas. It is a white, crystalline solid and is commonly used as a catalyst in organic synthesis.

Overall, the sequence represents a progression from elemental aluminum to various aluminum compounds through different chemical reactions.
