Los cambios energéticos en las reacciones

The video explains exothermic and endothermic reactions, focusing on energy changes. Exothermic reactions release energy, as seen in combustion, while endothermic reactions absorb energy, like in thermal decomposition. The breakdown of sodium acid carbonate in baking is an example of an endothermic reaction. The video also discusses how breaking and forming chemical bonds involve energy changes, determining whether a reaction is exothermic or endothermic.

Describe the role of heat in breaking down sodium acid carbonate in baking.

How does the balance between breaking and forming bonds determine if a reaction is exothermic or endothermic?
