The popularity of GNOME 2 is a reaction -- and you can't expect innovation from a reaction.
Very interesting game for verification of reaction, ability to recognize and memorize the colours
I understand that if we run an electrical current through water, it will decompose into its component parts (oxygen and hydrogen) according to the following chemical equation:
2 H2O -> 2 H2 + O2
I also know that this is an endothermic reaction (since the combustion of H2 is definitely exothermic).
