Question

Al- AL₂O₃- AL(OH)3- ALCL 3 ​

Answer 1

Ответ:

Объяснение:

4Al + 3O2 = 2Al2O3

Al2O3 + 3H2O = 2Al(OH)3

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

Answer 2

Там все очень легко, объяснять я не умею так что сразу ответ прекреплю

Answer 3

It looks like you've listed various chemical compounds and species related to aluminum (Al). Let me provide some information about each of them:

1. Aluminum (Al): Aluminum is a chemical element with the symbol Al and atomic number 13. It is a lightweight, silvery-white metal and is the third most abundant element in the Earth's crust. Aluminum is known for its low density and excellent corrosion resistance. It has a wide range of applications, including in the construction industry, aerospace, transportation, and packaging.

2. Aluminum Oxide (Al₂O₃): Aluminum oxide, also known as alumina, is a compound of aluminum and oxygen. It is a white or nearly colorless crystalline substance that occurs naturally as corundum, a valuable gemstone. Aluminum oxide is commonly used as an abrasive material and is also used in the production of ceramics and refractory materials.

3. Aluminum Hydroxide (Al(OH)₃): Aluminum hydroxide is an inorganic compound with the formula Al(OH)₃. It is a white, gel-like substance that is often used as an antacid to treat heartburn and upset stomach. Additionally, aluminum hydroxide is used as a flame retardant in some materials.

4. Aluminum Chloride (AlCl₃): Aluminum chloride is a chemical compound with the formula AlCl₃. It exists as a white or yellowish solid and is highly soluble in water. Aluminum chloride is commonly used as a Lewis acid in organic synthesis and as a catalyst in various chemical reactions. It is also used in some antiperspirants.

These compounds and species are important in various industrial and chemical applications, and they each have their own unique properties and uses.
