Exothermic means that a system (what you are studying) releases heat into the surroundings. it feels warm because heat exits out of the reaction. in enthalpy Delta H would be negative so it would be a spontaneous reaction.

Exothermic -- is a reaction which results in release of energy. ie energy is lost from the system.
Exo -- out
thermic - heat

~ the reaction liberates heat.
~ if you place the erlenmayer that has the reaction taking place in your hand, youll feel it hot because your hand is colder than the erlenmayer therefore your absorving its heat.

You gottta apply heat to it to make it happen.
