Growling Gummy Bears video "Screaming Jelly Babies" (British English), also known as "Growling Gummy Bears" (American and Canadian English), is a classroom chemistry demonstration in which a piece of candy bursts loudly into flame when dropped into potassium chlorate. [1]
The Old Nassau reaction or Halloween reaction is a chemical clock reaction in which a clear solution turns orange and then black. This reaction was discovered by two undergraduate students at Princeton University researching the inhibition of the iodine clock reaction (or Landolt reaction) by Hg 2+, resulting in the formation of orange HgI 2.
The carbon in the reaction makes the snake black. The overall process is exothermic enough that the water produced in the reactions is vaporized. This steam, in addition to the carbon dioxide product, makes the snake lightweight and airy and allows it to grow to a large size from a comparably small amount of starting material. [4]
A chemical reaction is a process that leads to the chemical transformation of one set of chemical substances to another. [1] When chemical reactions occur, the atoms are rearranged and the reaction is accompanied by an energy change as new products are generated.
Chemistry is the scientific study of the properties and behavior of matter. [1] It is a physical science within the natural sciences that studies the chemical elements that make up matter and compounds made of atoms, molecules and ions: their composition, structure, properties, behavior and the changes they undergo during reactions with other substances.
Video of a barking dog reaction by Maxim Bilovitskiy. The "Barking Dog" is an exothermic chemical reaction that results from the ignition of a mixture of carbon disulfide and nitrous oxide. [1] When ignited in a cylindrical tube, the reaction produces a bright flash and a loud "woof" - reminiscent of a barking dog.
"Curious George, Sea Monkey": George and The Man With the Yellow Hat travel on a boat with Professor Wiseman as well as Professor Pizza and Professor Einstein to retrieve a weather satellite that has fallen from space into the ocean. The only problem is that the satellite has fallen into the middle of a coral reef which is very brittle, so ...
Blue bottle reaction video. The blue bottle experiment is a color-changing redox chemical reaction. An aqueous solution containing glucose, sodium hydroxide, methylene blue is prepared in a closed bottle containing some air. Upon standing, it spontaneously turns from blue to colorless due to reduction of methylene blue by the alkaline glucose ...
