Nitric acid, HNO 3. In this case, one of the oxygen atoms can be thought of as attaching to the nitrogen via a co-ordinate bond using the lone pair on the nitrogen atom. flower shop in madison wv

"WebExothermic reactions are chemical reactions in which heat energy is given out.This is a result of bonds being created, which gives out/releases energy.If it helps, you can think of exit or expelled for 'exo', and 'thermal' for heat. (Exothermic describes any reaction/process that releases any form of energy, but only heat energy is studied at GCSE/IGCSE level). " - Bond energy definition chemistry gcse
