2. Blue bottle experiment - Wikipedia

   en.wikipedia.org/wiki/Blue_bottle_experiment

   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 ...

   For parents, he pushed the idea that the sets' use of chemical reactions directed their children toward a potential career in science and engineering. [ 2 ] In 1954, Gilbert wrote in his autobiography, The Man Who Lives in Paradise , that the Atomic Energy Laboratory was "the most spectacular of [their] new educational toys".

5. Chemical reaction - Wikipedia

   en.wikipedia.org/wiki/Chemical_reaction

   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.

6. List of chemistry mnemonics - Wikipedia

   en.wikipedia.org/wiki/List_of_chemistry_mnemonics

   An atom (or ion) whose oxidation number increases in a redox reaction is said to be oxidized (and is called a reducing agent). It is accomplished by loss of one or more electrons. The atom whose oxidation number decreases gains (receives) one or more electrons and is said to be reduced. This relation can be remembered by the following mnemonics.

7. Chemical energy - Wikipedia

   en.wikipedia.org/wiki/Chemical_energy

   Chemical energy is the energy of chemical substances that is released when the substances undergo a chemical reaction and transform into other substances. Some examples of storage media of chemical energy include batteries, [1] food, and gasoline (as well as oxygen gas, which is of high chemical energy due to its relatively weak double bond [2] and indispensable for chemical-energy release in ...
