橡皮糖熊之死(2)

Now let's see what happens when Dr. Dolhun adds the gummy bear Alright, so let's just break down what just happened

The sugar from the gummy bear and oxygen react to produce carbon dioxide and water

releasing a lot of energy as heat and light This is what that looks like

And I'm going to draw sucrose or sugar in a red because that's from the gummy bear

This reaction is probably familiar to you It's a combustion reaction

which has been a fuel reacts with oxygen to produce carbon dioxide and water and at the same time releasing a bunch of energy

So why is so much energy released and where does it come from? To show you, I'm going to draw the structures

Now if you're unfamiliar with organic chemistry notation each of the lines between the elements that I'm going to draw

represents a covalent bond which is the sharing of two electrons between two atoms

So let me draw those So here are the reactants
