Question

С чем взаемодействует Al2O3? 1.)K; 2)C2O; 3.)H2O; 4.)S; 5.)MgO

Answer 1

Відповідь: 3) H2O
Al2O3 + H2O

Answer 2

Al2O3 is the chemical formula for aluminum oxide, which is a compound composed of aluminum and oxygen atoms. Aluminum oxide can interact with various substances. Let's go through each option and see which ones it can interact with:

1. K (potassium): Aluminum oxide can react with potassium to form potassium aluminate, KAlO2. This reaction occurs when aluminum oxide is heated with potassium hydroxide (KOH) or potassium carbonate (K2CO3).

2. C2O (oxalate): There is no direct interaction between aluminum oxide and oxalate (C2O). However, aluminum oxide can be used as a catalyst in the decomposition of oxalate compounds, such as potassium oxalate (K2C2O4), into carbon dioxide (CO2) and potassium carbonate (K2CO3).

3. H2O (water): Aluminum oxide can react with water to form aluminum hydroxide (Al(OH)3). This reaction occurs when aluminum oxide is exposed to moisture or when it is dissolved in water.

4. S (sulfur): Aluminum oxide does not directly interact with sulfur (S). However, aluminum oxide can be used as a catalyst in certain reactions involving sulfur compounds, such as the oxidation of hydrogen sulfide (H2S) to sulfur dioxide (SO2).

5. MgO (magnesium oxide): Aluminum oxide and magnesium oxide can form a solid solution known as spinel. This occurs when aluminum oxide and magnesium oxide are heated together at high temperatures. The resulting compound is called magnesium aluminate (MgAl2O4).

In summary, aluminum oxide can interact with potassium, water, and magnesium oxide to form various compounds. It can also be used as a catalyst in reactions involving oxalate and sulfur compounds.
