1. Reaction with oxygen: Most of the metals form respective metal oxides when reacting with oxygen.
Metal + Oxygen → Metal Oxide
Examples:
Reaction of Potassium with Oxygen: Potassium metal forms potassium oxide when reacts with oxygen.

organic inorganic
it is study of the structure,composition and synthesis of carbon compound is called organic compound.
organic word comes from the intially known organic compounds which came from living things.The vital fotce_Berezulies the force supplied by living things are necessary for the production of organic compound.
AMMONIUM CYNATE UREA
NH4NCO(aq)___heat____ NH2CONH2(S)
this gave the death of vital force theory. Thousands of organic compounds are synthesised in various laboratries of the world. In world organic compound exceeds more than 3 million.
