Chemical experience with powder: how the powder explodes! The powder is smoke, or black, powder is a mixture of potassium selitre (calignite - KNO3), sulphur (S) and coal (C). It s flammable at about 300 °C. The powder could be blown up. It consists of oxidant (seliter) and reinstater (coal). The serial is also a reinstater, but its primary function is to connect the calium into a solid compound. When the powder burns, there is a reaction: 2KNO3+C+S circle K2S+N2+3CO2, which gives a large volume of gaseous substances

Today, in the output: simple electric motor on the battery; air balloon and -170°C; black sugar; free fall; dissolved shells; fuel for hydrogen machines. Attention: Some experiences can be hazardous to health. They need to be followed by security equipment. Below, look at six videos with explanations. Why is the wire spinning because there s an electrical charge in the wire? And that s nothing but an orderly motion of charged particles. Each of them has a magnetic field that deviates their direction. This rejection is called Lorenza s power. The…

The chlorine limb is used as a disinfectant and as a strong oxidant. 0, 5 g chlorine, cross the porcelain cup with several drops of salt acid. Gaseous chlorine is produced and determined by smell. Interesting studies can be carried out with a chlorine limestone on colour discoloration. To this end, prepare the meds in the water and let her stand. The visual layer It s common knowledge that the iodine solutions, when adding the solution to the edge, take the blue colour. Prepare a diluted aqueous solution of iodine (possible to use Lugol solution)…
