When Mercury (II) thiocyanate comes in contact with strong enough heat source, a rapid exothermic reaction is initiated that produces a large mass that appears like a winding “snake”. The chemical reaction is described below: Igniting mercury thiocyanate causes it to form an insoluble brown mass that is primarily carbon nitride, C3N4.

What happens when mercury sulphide reacts with oxygen?
