May 25 is the professional holiday for employees of the chemical industry.
On May 25, employees of the chemical industry celebrate their professional holiday.
Every year, on the last Sunday of May, Russia celebrates Chemist's Day. The chemical industry makes a significant contribution to providing the population with necessary products and services, influences the development of other sectors, and is constantly improving. The work of chemists is important in industrial production, scientific research, solving environmental challenges, and many other areas.
Interesting facts about chemistry:
- The length of a chain of 100 млн hydrogen atoms is only 1 см.
- Fluorine is the most chemically reactive nonmetal; it reacts with almost all substances, and with many of them it can cause combustion and explosions.
- Iron melts at temperatures above 1 539 °C, and turns into a gas at 2 862 °C.
- Cutting an onion without tears is difficult because of the sulfuric acid that forms as a result of a chemical reaction when the onion's cells are ruptured. Experiments have shown that there is a lower likelihood of tearing and burning if you cut an onion with a thin, sharp knife. A poorly sharpened knife cuts with greater force and damages the surface more severely.
- The walls of a soap bubble are one of the thinnest materials a person can see without special equipment. They are approximately 200 times thinner than a human hair.
We congratulate chemical industry workers on their professional holiday! We wish you health, success, and safe working conditions!
