Life common chemical phenomena
????? A lipstick: Lipstick Lady in oil, beeswax, titanium dioxide, and dyes, a dye composition of the two chemicals, a fluorescein, a bromine.
2, chewing gum: it is derived from the isoprene out of glue is made, in addition, the chewing gum also contains other chemical components, sweetener, flavoring agents and softeners. Chewing gum can blow Photoluminescent Masterbatch bubbles is because of containing butyl rubber.
3, sunscreen: two: one can reflect sunlight, and the other one is light before it reaches the skin absorption; first is called a "physical sunscreen" the second is "chemical sunscreen" chemical sunscreen benzoic acid containing an amino group, can absorb electromagnetic radiation and convert it into other forms of energy without hazards.
4, remove wrinkles: "alpha hydroxyl acid" compound "beta hydroxyl acid" contains cream, which can be extracted from fruit and milk. Can dissolve the dead cells adhered to human skin fat, this fat is eliminated, a new skin, reducing wrinkles.
5. Environmental pollution caused by heavy metals called heavy metal pollution. Heavy metal pollution can sometimes cause great harm, such as Minamata disease occurred in Japan (mercury contamination) and bone pain disease (cadmium pollution) and other pollution disease, is caused by the heavy metal pollution.
6 There is a laughable gases. It is one of the relatives of nitrogen. Called nitrous oxide, nicknamed "laughing gas." "Laughing gas" as an anesthetic, but soon entered the hospital, and was a long-term use. The use of anesthetic, so many patients freed from the hands of death out.
7 make cookies, cakes and breads and other foods when used another baking powder. This has nothing to do baking powder and yeast, in fact, is a chemical leavening agent. It contains two chemical powder - sodium dihydrogen phosphate and pigment powder suppliers sodium bicarbonate, into the wet surface, the change in the chemical, carbon dioxide gas to emerge, the food produced in many Xiaodong Dong.
8 fried dough fritters rub it in advance of the food base and alum. Shop early master said, "a base two alum three salt" refers to every seven pounds of fresh surface coupled with twelve bases, twenty-two thirty-two alum and salt, then into a deep-fried dough fritters. These three roles each have their own role in chemistry: salt so salty surface and become pliable, alum is potassium aluminum sulfate, acidic, in hot pan, it and the food base from a chemical reaction to produce carbon dioxide bubbles, the rapid expansion of heated air bubbles, making fritters quickly swell. One or two food base and two two alum can produce about 14 liters of carbon dioxide gas, boiling oil temperature more than two degrees, the expansion of the volume and make it more than doubled, so the new deep-fried fritters porous.
9 special glass called "photochromic" glass. It is in the manufacturing process, the pre-light-sensitive material braced as silver chloride, silver O (collectively halide), as well as a small amount of copper oxide catalyst. Glasses from no color becomes light gray, dark brown, photoluminescent pigment suppliers and then change back from the dark tone through glasses glasses are silver halide becomes magic. "
