Question

Al-Al2O3-AlCL3-Al(NO3)3-Al2(SO4)3-Al(OH)3-Al2O3-Na3AlO3

Answer 1

2Al+Fe2O3=Al2O3+2Fe

Al2O3+6HCl=2AlCl3+3H2O

AlCl3(безводн.)+3HNO3(конц.)=Al(NO3)3+3HCl

2Al(NO3)3+3Na2SO4=380°C=6NaNO2+3O2+Al2(SO4)3

Al2(SO4)3+6NaOH=2Al(OH)3+3Na2SO4

2Al(OH)3=Al2O3+3H2O

Al2O3+6NaOH=t°C=2Na3AlO3+3H2O

Answer 2

The given sequence appears to be a list of chemical compounds involving aluminum (Al) and oxygen (O), as well as other elements and ions. I'll provide some information on each of these compounds:

1. Al: This simply represents aluminum, which is a metallic element with the atomic number 13.

2. Al2O3: This is aluminum oxide, also known as alumina. It is a compound made up of two aluminum atoms and three oxygen atoms and is commonly used as a refractory material, as well as in the production of ceramics and glass.

3. AlCl3: This is aluminum chloride, a compound containing one aluminum atom and three chlorine atoms. It is a strong Lewis acid and finds applications in various chemical processes.

4. Al(NO3)3: This is aluminum nitrate, a compound consisting of one aluminum atom and three nitrate ions (NO3-). It is used in various chemical reactions and as a mordant in textile dyeing.

5. Al2(SO4)3: This is aluminum sulfate, a compound made up of two aluminum atoms and three sulfate ions (SO4^2-). It is used in water treatment, paper manufacturing, and as a mordant in dyeing.

6. Al(OH)3: This is aluminum hydroxide, a compound composed of one aluminum atom and three hydroxide ions (OH-). It is used as an antacid and in the production of aluminum-based pharmaceuticals.

7. Al2O3-Na3AlO3: This seems to be a mixture of aluminum oxide (Al2O3) and sodium aluminate (Na3AlO3). Sodium aluminate is a compound formed when aluminum oxide reacts with sodium hydroxide.

Please note that the compounds listed above have various industrial and chemical applications, and their properties and uses can vary based on the context in which they are used. Additionally, the list does not seem to follow a specific pattern, so it's essential to provide more context or clarify the purpose of this list if you need more specific information.
