Summary

Description
English: Pharaoh's snake

- Mercury(II) thiocyanate is white flammable solid. When ignited it burns giving elemental mercury (probably a minor part of HgO, as well), carbon and sulfur as solid products, but also carbon dioxide and sulfur oxides as gaseous products. The gas products enable the formation of voluminous foamy solid product (mainly composed out of carbon and sulfur) that “grows”. Due to the shape of the foam and the way the reaction proceeds, the experiment is known as a Pharaoh's snake.

Planned and performed by Marina Stojanovska, Miha Bukleski and Vladimir Petruševski, Department of Chemistry, FNSM, Ss. Cyril and Methodius University, Skopje, Macedonia.
Македонски: Фараонова змија

- Жива(II) тиоцијанат е цврста супстанца која е лесно запалива. Кога гори се образува елементарна жива (веројатно и мал дел HgO), јаглерод, сулфур, но и гасовити продукти како јаглерод диоксид и сулфурни оксиди. Гасовитите компоненти овозможуваат да се создаде волуминозен цврст продукт (јаглерод и сулфур) со сунѓереста структура кој како да „расте“, а заради обликот, како и текот на реакцијата, експериментот е наречен фараонова змија.

Осмислено и изведено од Марина Стојановска, Миха Буклески и Владимир Петрушевски, Институт за хемија, ПМФ, УКИМ, Скопје.
