Crazy talk

I did not do chemistry but i was wondering do flames(by extension chemical reactions) have weight?
i know such reactions are due to the materials trying to reach equilibrium but could there be a weight attached to the reaction itself? 
if there is who was the first to measure it ,if not how come?

i dont do drugs and was completely sober when i wrote it

Fire's weight: Fire or flames is really just gases and
particles from the burning material that are so hot that they glow. Even
though it would be hard to weigh fire, it is made of stuff that does
have weight -- although, nothing major.

good answer there but if he meant  the actual visible flame  and not the burning gass then the answer would be yes and no. all the actual visible flame is  are photons,  light particles which in theory does have weight  if viewed as a particle but are weightless if viewed as a wave of radiant energy

     chemical reactions do not have weight  i think.. they involve  electrical bonds  breaking and forming , and the end result ( unless something boils off) is the same mass as wat you started off with , just the energy level has changed and the chemicals are bonded to different chemicals . 
    You might as well ask if electricity or light has weight...   they are supposedly waves of energy so they don't ....     
     
  Then again i do remember one of my many  physics teachers mentioning nuclear fuel loosing like .00001% every time it goes through the reactor , the matter is turned into pure enegry , e=mc 2 ...    so possibly in a chemical reaction the reactants loose a portion of its mass to energy , but its so small  that it cant' be measured...
     
  Also if it so.. it means that after a few  zillion years  the universe will be  made of pure energy O_O ...  That is unless energy turns back into matter .
