Why does the chemical expression of the reaction between aluminum and oxygen remain unchanged?
The reaction between aluminum and oxygen forms aluminum dioxide, and its chemical equation is 4AI +3O <2>= 2AI <2> O. This chemical expression did not change for the following reasons: 1. The law of conservation of atoms: In a chemical reaction, atoms will not be created or destroyed, they will only be reassembled. The type and number of aluminum atoms and oxygen atoms remained unchanged before and after the reaction. Before the reaction, aluminum was a single aluminum atom, and after the reaction, it existed in the aluminum dioxide molecules. Before the reaction, oxygen atoms existed in the form of oxygen molecules, and after the reaction, they existed in the aluminum dioxide molecules. 2. ** The chemical properties of aluminum and oxygen are stable. ** When aluminum reacts with oxygen, due to the outermost electronic structure of the aluminum atom, it tends to lose electrons and combine with oxygen atoms to form a stable compound structure such as aluminum dioxide. There were covalent bonds between the oxygen atoms in the oxygen molecules. When it reacted with aluminum, this covalent bond was broken and reassembled with the aluminum atoms to form a new chemical bond. The aluminum dioxide structure formed after the reaction was stable, allowing the reaction to proceed according to this chemical equation. 3. ** Energy angle **: This reaction is carried out according to 4AI +3O ^= 2AI ^O ^, and the energy before and after the reaction reaches a stable state. In the energy conversion process from the reagents aluminum and oxygen to the product aluminum dioxide, this relationship between the two allowed the reaction to occur in the most stable energy state, and under certain reaction conditions (room temperature or ignition, etc.), it was the only energy-favorable reaction method.
