Question

Составить цепочку H2O2-O2_Al2O3 _FeO

Answer 1

1. 2H2O2= 2H2O+O2
2. 3O2+4Al=2Al2O3
3. 2Al2O3+6Fe=6FeO+4Al

Answer 2

H2O2 - O2 - Al2O3 - FeO

H2O2: Hydrogen peroxide is a chemical compound composed of two hydrogen atoms and two oxygen atoms. It is a pale blue liquid that is commonly used as a bleaching agent, disinfectant, and oxidizer.

O2: Oxygen is a diatomic molecule consisting of two oxygen atoms bonded together. It is a colorless gas that is essential for respiration and combustion processes. Oxygen is abundant in the Earth's atmosphere, making up about 21% of the air we breathe.

Al2O3: Aluminum oxide, also known as alumina, is a compound composed of two aluminum atoms and three oxygen atoms. It occurs naturally as the mineral corundum and is widely used in various industries. Aluminum oxide is a white solid with high hardness and is valued for its electrical insulating properties, heat resistance, and as an abrasive.

FeO: Iron(II) oxide, also known as ferrous oxide, is a compound consisting of one iron atom and one oxygen atom. It is a black solid that forms when iron reacts with oxygen. Iron(II) oxide is used in the production of iron and steel, as a pigment in paints, and as a catalyst in chemical reactions.

Therefore, the chain is: H2O2 - O2 - Al2O3 - FeO
