Question

Al=AlC3=Al(OH)3=Al2O3

Answer 1

Ответ:

2Al (порошок)+ 3Cl2 → 2AlCl3

AlCl3 + 3NaOH (разб. р-р)→ Al(OH)3 + 3NaCl

2Al(OH)3 → Al2O3 + 3H2O

Объяснение:

Answer 2

It seems like you're trying to represent various compounds involving aluminum (Al) in a condensed form. Let me break down what each of these compounds typically represents:

1. Al: This usually represents pure elemental aluminum, which is a metallic element with the chemical symbol Al.

2. AlCl3: This represents aluminum chloride, which is a compound formed when aluminum reacts with chlorine. Its chemical formula is AlCl3.

3. Al(OH)3: This represents aluminum hydroxide, which is a compound formed when aluminum reacts with water. Its chemical formula is Al(OH)3.

4. Al2O3: This represents aluminum oxide, which is a compound composed of two aluminum atoms and three oxygen atoms. Its chemical formula is Al2O3.

Each of these compounds has its own distinct properties and uses:

• Aluminum (Al) is a lightweight, silvery-white metal commonly used in various applications due to its low density and good conductivity.

• Aluminum chloride (AlCl3) is a chemical compound often used as a catalyst in chemical reactions or as an ingredient in certain industrial processes.

• Aluminum hydroxide (Al(OH)3) is used in antacid medications and as a flame retardant in some applications.

• Aluminum oxide (Al2O3), also known as alumina, is a versatile material with uses ranging from being a key component in ceramics and refractory materials to being used in abrasive products like sandpaper.
