Welcome, young supporters of chemistry circle foam definition on the page "Himikus - Tsikavikus." Our group is designed for curious explorers of the world, those who do not consider boring foam definition chemistry who are interested in the unusual properties of all known and unknown substances!
Oxygen foam very interesting experiment! As we know, oxygen can be extracted schedule oksyhenovmisnyh compounds. Earlier in the circle we have conducted experiments on the extraction of oxygen from potassium permanganate and hydrogen peroxide. The program 7th grade, we also performed practical work on the extraction of oxygen and study its properties. But yesterday foam definition we modified the experiment on the extraction of oxygen from hydrogen peroxide and added to the reaction mixture gel. It was a lot of fun! Oxygen, which was formed by the decomposition of peroxide in the presence of a catalyst (2H 2 O 2 = 2H 2 O + O 2), spinyuvav gel. We conducted several experiments, changing catalysts - potassium permanganate, manganese (IV) oxide, copper Ammoniate. In each case, spillovers reactions were different but very interesting! We offer see our video. foam definition So far it is imperfect, but Stanislav hem, a student of M-31 helps us create videotapes the experiments, we then show you how. So see and rejoice with us:
Very interesting experiment. By the way, today we conducted the experiment again. It was interesting. Also tried to hold the gel experiment without oxygen and immediately freed. It was unexpected but interesting. March 30, 2011 18:56
Did you know that ...
The temperature in the trunk of lightning reaches 20 000 C, while nitrogen reacts with oxygen, leading to the formation of about 2 million tons of nitric acid daily (or 700 million tons per year) World production of nitric acid is about 30 million tons per year
