Finally, lets look at a chemical reaction that matters to you, such as combustion, which is the net result of how we use the oxygen we breathe to yank electrons away from the carbon atoms in the food we eat. Chemists talk about the “electronegativity” of the oxygen molecule, what this jargon means is that molecular oxygen, the O2 we breathe, represents a deeper potential well for an electron than does a carbon-hydrogen bond such as the ones in fat and sugar. This is why we can “oxidize” these fuels. Another way to think of it is that fat or sugar are fuel sources which represent concentrations of electrons with high electrostatic potential and being bound to an oxygen nucleus is a pit into which these electrons fall in order to dissipate that electrostatic potential. When this happens, heat is realeased (it’s combustion). This heat represents the further probabilistic mixing of the universe which is the true rationale for why combustion occurs in the first place. If it weren’t entropically favorable to release heat to the surroundings, combustion would not occur, and you would not breathe oxygen or be here in the first place.
