The above chemical equation describes the reaction between aluminum oxide (Al2O3) and hydrogen (H2) to form aluminum (Al) and water (H2O).
-
Reaction conditions: For the reaction to occur, aluminum oxide and hydrogen need to be heated to a high temperature. Another condition is that the pressure must be maintained at an appropriate level.
-
Reaction process: When aluminum oxide and hydrogen are heated, the molecules of these two substances begin to react with each other. The aluminum atoms in aluminum oxide combine with the hydrogen atoms to form aluminum and water.
-
Visible phenomena: When the reaction occurs, changes in color and temperature can be observed. The color of the mixture will change from the white of aluminum oxide to the silver of aluminum. In addition, since the reaction occurs at high temperature, there may be an exothermic phenomenon, that is, an increase in temperature and the release of steam.
