Question

A chemist wants to observe the following reaction:

2H2 + O2 à 2H2O
The chemist is standing beside a balloon filled with hydrogen. When the chemist holds a small flame up to the hydrogen balloon, the balloon pops, the hydrogen filled balloon explodes in a ball of fire.Based on what you know about breaking and forming bonds, which part of the reaction has a higher bond energy in the balloon video, the reactants or the products formed?
The bond energy in the reactant O2
The combined energy of the reactants H 2 + O 2
The bond energy in the reactant H 2
The bond energy of the product H20

Based on what we know about breaking and forming bonds, the bond energy in the reactants (H2 and O2) is higher than the bond energy of the products formed (H2O) in this reaction. This is evidenced by the explosive reaction that occurs when the balloon filled with hydrogen reacts with oxygen - the breaking of the bonds in the reactants releases a large amount of energy.
