Sulfur comes in very easily in the reaction. When connecting other elements to sulfur, a flash often occurs. Thus, for example, when a mixture of sulfur and lead dioxide is triturated, a flash occurs in the mortar...

Sulfur acts as an oxidizer for metals. Sulfur with metals very easily connects. Therefore, there are many sulfurous metals in nature. These are the ores from which metals are mined. Sulfur combines directly with almost all metals, releasing heat. It is necessary only in one place to set fire to mixtures of sulfur with metals, and the reactions...

Glass, from which glass windows are made, is called ordinary glass. The chemical composition is sodium-calcium hexasilicate Na₂CaSі₆O₁₄, or Na₂O*СаО*6SіО₂. Modern science, technology, and even everyday life can not be satisfied only with this, because it has many shortcomings...

Experience - Fireworks with H₂SO₄ and KMnO₄. In a small cylinder (250 ml), pour 50 ml of concentrated H₂SO₄. Carefully along the wall of the cylinder (so that the liquids do not mix) pour the same volume of wine alcohol from above. KMnO₄ crystals are poured into the liquid in small portions...

An interesting crystallization phenomenon can be observed in some salts. There are salts that have the property of glowing during crystallization. To demonstrate this phenomenon, you need to have a chemically pure potash and Sulfuric acid potassium in the form of saturated solutions...

Diamonds from alcohol? Someone with doubt shakes his head. However, the technique for obtaining diamond microcrystals from alcohol vapors has long been developed at the Japanese Institute of Technology, located near Tokyo. It is simple: a silicone plate is placed in a sturdy cylindrical vessel 50 cm in diameter...
