Question
Write like an 8th grader. A chemist wants to observe the following reaction:
2H2 + O2 → 2H2O
The chemist is standing inside a room with oxygen in the air and has a balloon filled with hydrogen. The chemist holds a small flame up to the hydrogen balloon. When the balloon pops, the hydrogen explodes in a ball of fire.
explain which part of the reaction is higher in energy

In the reaction 2H2 + O2 → 2H2O, we have hydrogen (H2) and oxygen (O2) combining to form water (H2O). To figure out which part of the reaction is higher in energy, we need to look at the bonds in the molecules involved.
Hydrogen has weak bonds because H2 (hydrogen gas) is made up of two hydrogen atoms held together with a pretty small amount of energy. On the other hand, oxygen (O2) has stronger bonds because two oxygen atoms are held together with a bit more energy than hydrogen.
When the chemist holds a small flame to the hydrogen balloon, that energy from the flame is enough to break the hydrogen molecules apart and mix with oxygen. When they combine to form water, they make new bonds that are much stronger than the old bonds in hydrogen and oxygen.
So, before the reaction starts, the hydrogen and oxygen have higher energy because the bonds are weaker. But once the reaction happens and water is formed, it releases energy. That's why the balloon popping creates a big explosion and a fireball!
In conclusion, the hydrogen gas (H2) is higher in energy compared to the water (H2O) that is made during the reaction.
