Noun
chemical reaction- A process, involving the breaking or making of interatomic bonds, in which one or more substances are changed into others.
...A chemical reaction is a process that leads to the transformation of one set of chemical substances to another. They are studied by chemists under a field of science called chemistry. Chemical reactions can be either spontaneous, requiring no input of energy, or non-spontaneous, often coming about only after the input of some type of energy, viz. heat, light or electricity. Classically, chemical reactions encompass changes that strictly involve the motion of electrons in the forming and breaking of chemical bonds, although the general concept of a chemical reaction, in particular the notion of a chemical equation, is applicable to transformations of elementary particles, as well as nuclear reactions.

A. The production of new atoms is called a nuclear reaction. Since we name all atoms by the number of protons and then number of neutrons remain constants under most conditions for an atom, any change in these numbers are called nuclear reactions. Reactions that happen fairly easily are called chemical reactions. These happen when you just mix two substances together and they trade or share electrons to group themselves differently. |

What type of chemical reaction I need to come up with a
chemical reaction that will
cause a decrease in volume
when it occurs in an enclosed
environment.
The easier and more naturally
that the reaction occurs the
better. I would prefer that it
be exothermic.
This is just theoretical, so
you don't have to worry about
access to chemicals, and
there's no need to fear
recommending something
dangerous to me, because I
won't be trying it in real
life.

Burning magnesium ribbon in air will remove oxygen gas, converting the Mg to MgO and reducing the volume. There must be loads more where ignition produces a solid product |

What is the chemical reaction I just want to know the
chemical reaction that
occurred during the Hindenburg
disaster. I know it had to do
with static electricity and
hydrogen gas, but I don't know
the exact chemical reaction.
Help!

Ironically, the rxn was H2 + 1/2O2 -> H2O. However, not enough water was created to quench the flames of the exploding hydrogen, although the moving pictures of the disaster clearly show the water. |
