Question

Use the scenario to answer the question. A student has a balloon filled with hydrogen gas. While wearing safety gear, they hold a flame up to the balloon. It explodes with a loud bang and creates a fireball. Is this an endothermic or exothermic reaction, and why?

Answer 1

Answer:

Exothermic reaction

Explanation:

An endothermic reaction absorbs energy, while an exothermic reaction releases energy. In this scenario, the balloon explodes with a loud bang and creates a fireball which would be considered releasing energy. Therefore, the reaction taking place is exothermic.
