WebA chemical reaction will happen and the baking soda will bubble up releasing a gas. 2. What do you think will happen to the balloon attached? It will inflate 3. Why does the balloon stop blowing up (why does the reaction stop)? WebChemical reactions can involve the breaking of existing chemical bonds, the formation of new bonds, or both. The evaporation of sweat does not involve any chemical changes but it does involve a change in physical phase (from liquid to vapour). Therefore, evaporation is said to be a physical endothermic process rather than an endothermic reaction.
