Question

H2S=H2O=O2=Al2O3 дуже потрібно​

Answer 1

Ответ:

Объяснение:

H₂S→H₂O→O₂→Al₂O₃

2H₂S+3O₂=2H₂O+2SO₂ (при избытке кислорода)

2H₂S+O₂=2H₂O+2S (при недостатке кислорода)

2H₂O=O₂+2H₂(электролиз воды, разложение воды под действием электрического тока)

3O₂+4AI=2Al₂O₃

Answer 2

Ответ:

Объяснение:

1. 2H2S+3O2= 2SO2+ 2H2O

2. 2H2O= 2 H2+O2

3. 4Al+ 3O2=2Al2O3

Answer 3

It seems like you have written a series of chemical formulas: H2S, H2O, O2, and Al2O3. These formulas represent different chemical compounds:

1. H2S: Hydrogen sulfide, a colorless gas with a characteristic foul odor.
2. H2O: Water, a colorless and odorless liquid essential for life on Earth.
3. O2: Oxygen gas, which is essential for respiration and combustion.
4. Al2O3: Aluminum oxide, a compound commonly known as alumina, found in various forms like ruby, sapphire, and in the mineral corundum.

It's important to note that these are separate and distinct chemical compounds. If you have any specific questions or concerns related to these compounds or their properties, feel free to ask, and I'll be happy to assist you further!
