 Who says chemistry needs to be complicated?
Reactions can be very basic, in fact cooking an egg is an example of a chemical reaction, these reactions are seen as non-reversible. The properties at an atomic level have changed and thus meaning that it cannot change back into the structures the atoms had previously. Another good example would be a firework, the rapid oxidation is an example of a chemical change. |
