What chemical reaction occurs when ammonium dichromate and mercury thiocyanate are combined?
When ammonium dichromate and Mercury thiocyanate are combined, a chemical reaction called a decomposition reaction occurs. This reaction produces a visually striking effect known as the "Pharaoh's serpent" or "Pharaoh's snake," where a dark, coiling mass of solid material is formed.

What are the chemical properties and reactions of ammonium dichromate and mercuric thiocyanate when combined in a controlled environment?
When ammonium dichromate and mercuric thiocyanate are combined in a controlled environment, they undergo a chemical reaction that produces a visually striking effect known as the "Pharaoh's serpent" or "Pharaoh's snake." This reaction involves the decomposition of the ammonium dichromate into chromium(III) oxide, nitrogen gas, and water vapor, while the mercuric thiocyanate decomposes into mercury(II) sulfide, carbon disulfide, and nitrogen gas. The resulting products expand and form a dark, snake-like structure due to the release of gases and the formation of solid compounds. This reaction is highly exothermic and should only be conducted in a well-ventilated area with proper safety precautions.
What happens when NH4Cr2O7 and HgSCN are combined?
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.
What is Sodium Thiocyanate Formula?
KSCN or K+ + SCN- when in aqueous solution
Is ammonium chloride an element compound or mixture?
Ammonium chloride is a compound, as it is composed of two different elements, ammonium and chloride, combined in a fixed ratio through chemical bonding.
What mean of NH4Cl2?
NH4Cl2 is not a valid chemical formula as it combines two different naming conventions - ammonium (NH4+) and chloride (Cl-). The correct formula for ammonium chloride is NH4Cl, where one ammonium ion is combined with one chloride ion.

30g of ammonium dichromate and 20 g of magnesium sulfate combined which will be the limiting factor?
Reactants: 30 g (NH4)2Cr2O7, 20 g MgSO4 30 g (NH4)2Cr2O7 / 252.07 g/mol = 0.119 mol 20 g MgSO4 / 120.41 g/mol = 0.166 mol Since they react in a 1:1 ratio to form magnesium dichromate and ammonium sulfate, ammonium dichromate is the limiting reagent (only 0.119 mol of MgSO4 is needed to react with all the (NH4)2Cr2O7).
Is ammonium chloride an element compound or mixture?
Ammonium chloride is a compound, as it is composed of two different elements, ammonium and chloride, combined in a fixed ratio through chemical bonding.
Where can one learn how to make ammonium chloride?
The internet is full of useful ways on how to make ammonium chloride. Hydrochloric acid, and ammonia can be combined to produce a chemical reaction which creates ammonium chloride.
Is dichromate insouble?
Most dichromates, except of alkali metals, are insoluble in water

What is the chemical formula for mercury I sulfate plus ammonium nitrate?
The equation is:Hg2SO4 + 2 NH4NO3 = Hg2(NO3)2 + (NH4)2SO4
What is NH3NO4?
NH3NO4 is not a valid chemical formula. It appears to be a mixture of two compounds, ammonia (NH3) and ammonium nitrate (NH4NO3), which are not chemically combined. Ammonium nitrate is a common fertilizer and explosive compound.
What happen if the ammonium chloride and water combined?
When Ammonium Chloride and water are combined and drop in temperature occurs because a endothermic reaction happens
Is ammonium chloride an element?
no, it is two elements that are combined into a compound. look at the name. ammonium which is nitrogen and 3 hydrogen combined. and chloride which is the element chlorine.
