Visualizing Energy Changes in Chemical Reactions through Reaction Profiles

The video tutorial explains reaction profiles and energy changes in chemical reactions. It covers energy conservation, exothermic and endothermic reactions, and their examples and uses. Exothermic reactions release energy to the surroundings, while endothermic reactions absorb energy. Examples include combustion and decomposition reactions, with applications like self-heating cans and sports-injury packs.

How do reaction profiles illustrate energy changes during chemical reactions?

Provide examples of endothermic reactions and their applications.
