    英文回答：
    The Fiery Serpent: An Experimental Exploration.
    The pharaoh's serpent is a simple yet striking chemical reaction that produces a serpentine form from a small mound of powder. Named after the biblical serpent that Moses transformed into a rod, this reaction offers an engaging demonstration of the power of chemical reactions.
    Materials:
    Ammonium dichromate powder.
    Candle or lighter.
    Fire-resistant surface.
    Procedure:
    1. Place a small pile of ammonium dichromate powder on a fire-resistant surface.
    2. Light the candle or lighter and hold it close to the powder.
    3. Observe the reaction as the powder ignites and transforms into a long, snake-like form.
    Chemical Reaction:reaction mass
    The pharaoh's serpent is a thermite reaction, which involves the rapid oxidation of a metal fuel. In this case, the fuel is ammonium dichromate, which contains chromium and oxygen atoms. When heated, the oxygen atoms are released, reacting with the chromium atoms to form chromium oxide. The reaction is exothermic, releasing heat and forming a molten mass.
    As the molten chromium oxide flows down, it solidifies and creates the characteristic serpentine shape. The continuous release of oxygen and chromium oxide sustains the reaction, causing the "serpent" to grow and writhe.
    Safety Precautions:
    Always wear safety goggles and gloves when performing the experiment.
    Use a fire-resistant surface to prevent burns or damage.
    Keep the reaction away from flammable materials and do not point it at people or pets.
    Allow the reaction to cool completely before discarding the remains.
    Scientific Inquiry:
    The pharaoh's serpent can serve as a starting point for further scientific inquiry into:
    Thermochemistry and exothermic reactions.
    The role of oxygen in combustion reactions.
    The properties of metal oxides and their applications.
