When ammonium dichromate (NH4Cr2O7) and mercury thiocyanate (HgSCN) are combined, a chemical reaction occurs that produces a dramatic and visually striking effect known as the "Pharaoh's Serpent" or "Pharaoh's Snake." This reaction results in the formation of a dark, snake-like solid that appears to grow and expand rapidly, accompanied by the release of gases such as nitrogen and water vapor. The reaction is exothermic, meaning it releases heat energy, and the resulting solid is primarily composed of mercury sulfide (HgS) and other byproducts.
NH4Cr2O7 is the chemical formula for ammonium dichromate, a compound used in pyrotechnics as a flame colorant. When heated, it decomposes into nitrogen gas, water, and chromium(III) oxide, resulting in a vibrant green flash. Due to its toxic nature and potential for explosion, it is handled with caution.
The reaction between an acid and an alkali is known as a neutralization reaction. In this reaction, the acid reacts with the alkali to form water and a salt.
The reaction between magnesium and oxygen is a combustion reaction, also known as a redox reaction. Magnesium reacts with oxygen to form magnesium oxide.
The reaction between hydrogen peroxide and acetic acid produces water and oxygen gas as products. This reaction is known as a decomposition reaction.
