Реакция взаимодействия лития и кислорода с образованием оксида лития. Реакция протекает при температуре выше 200°C. Примесь: пероксид лития Li2O2.

Answer 3

Li + O2 refers to the reaction between lithium (Li) and oxygen (O2). This reaction is a combination reaction where lithium reacts with oxygen to form lithium oxide (Li2O). The reaction can be represented by the following equation:

2Li + O2 -> 2Li2O

Here is a step-by-step breakdown of the reaction:

1. Step 1: The reactants are lithium (Li) and oxygen (O2).

2. Step 2: The balanced chemical equation for the reaction is 2Li + O2 -> 2Li2O. This equation shows that 2 moles of lithium react with 1 mole of oxygen to produce 2 moles of lithium oxide.

3. Step 3: In the reaction, each lithium atom (Li) loses one electron to form a lithium ion (Li+). This is because lithium has one valence electron and tends to lose it to achieve a stable electron configuration.

4. Step 4: The oxygen molecule (O2) consists of two oxygen atoms. Each oxygen atom gains two electrons to form oxide ions (O2-). This is because oxygen has six valence electrons and tends to gain two electrons to achieve a stable electron configuration.

5. Step 5: The lithium ions (Li+) and oxide ions (O2-) combine to form lithium oxide (Li2O). The lithium ions and oxide ions attract each other due to their opposite charges, resulting in the formation of a solid compound.

6. Step 6: The final product of the reaction is lithium oxide (Li2O), which is a white crystalline solid.

Please note that the above explanation is based on the general principles of chemical reactions. For more specific information or experimental details, it is recommended to refer to reliable chemistry textbooks or scientific literature.
