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.
In the video, what evidence is there that there was more bond energy when the products were formed?
The small amount of energy applied by the flame held up to the balloon
The balloon being inflated.
The balloon staying up in the air while inflated.
The hydrogen burning and exploding
The reaction of the exploding balloon is an example of an exothermic reaction?
True
False

Answer 1

[AI-generated answer — Bot GPT 3.5]

The evidence that there was more bond energy when the products were formed is the fact that the hydrogen burned and exploded. This release of energy indicates that new, more stable bonds were formed in the products (water). Therefore, the statement "The reaction of the exploding balloon is an example of an exothermic reaction" is true.
