of the republic of belarus , born in the city of minsk, graduated from the chemical faculty, belgos universitiesspecialist in the field of colloid chemistry. uh, at a young age i was fond of sports, but today i am responsible for the education and upbringing of our amazing generation in our country. let's look at how many questions you 'll see who starts. hello, my name is adeline. i have a question for you, but according to the theory of evolution, each subsequent generation. i have the previous you agree with this. yes, but then we are smarter than you. well, i think first of all that today is a very dynamic and it differs in that a very huge amount of information that comes in general as a whole, not only to the younger generation, but also to us adults and it seems to me that the current young generation. it is probably more stress-resistant to such a volume of information in this one. you are probably smarter than us, and what then is the problem of our generation? well, the problem is that in this large stream, one must not only be free to feel free, but be able to choose the information t

possible, simple and clear, i promised to tell the deputy dean of the faculty of chemistry belgo from the universitynatalya hello. so what is such a crunch from a chemical point of view and how it happens. good afternoon. i am very happy to welcome everyone to the studio. and if we now talk about crystal, then first of all we should decide. we just want to understand that the word is crystal, and accordingly, if we are talking about rock crystal, like the mineral, then the chemical formula of rock crystal is silit, the sum of two would like to be noted. what an interesting the fact that even in chemistry lessons at school, but they always said that two silicium is the formula of sand, and so, indeed , sand crystal has the same formula from a chemical point of view, however, depending on the location of the structural units of the crystal lattice . we can observe either rock crystal, or, well, it can be sand, if we talk about crystal as dishes , that is, when we talk about crystal dishes, then, accordingly, the main base is still the main base and we are two silicates, but at that same time. and addi
