Question

Al→Al2O3→Al(OH)3→Al2O3→Al2(SO4)3

Answer 1

Ответ:

4Al+ 3O2=2Al2O3

Al2O3+3H2O=2Al(OH)3

2Al(OH)3=Al2O3+3H2O

Al2O3+ 3H2SO4=Al2(SO4)3+ 3H2O

Answer 2

It looks like you've provided a sequence of chemical reactions involving aluminum (Al) and various compounds. Let's break down each step in the sequence:

1. Al: This represents elemental aluminum, which is a metal.

2. Al2O3: This represents aluminum oxide, also known as alumina. It's a compound composed of two aluminum atoms and three oxygen atoms (Al2O3). Alumina is commonly found in nature as the mineral corundum and is used in various industrial applications.

3. Al(OH)3: This represents aluminum hydroxide, which is a compound consisting of one aluminum atom and three hydroxide ions (OH-). It's often used in pharmaceuticals, as an antacid, and in the production of aluminum metal.

4. Al2O3: This step brings us back to aluminum oxide (alumina). It's not clear from your sequence how this step is connected to the previous one, as no specific reaction is mentioned.

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

If you have specific questions about each step or if you'd like to clarify the reactions or context behind this sequence, please provide more information, and I'd be happy to help!
