application of endothermic reaction
Answers
Answer:
Endothermic Chemical Reactions
A good example of an endothermic reaction includes dissolving a salt. It doesn't have to be table salt, nor does the solvent need to be water.
The reaction of barium hydroxide octahydrate crystals with dry ammonium chloride
Dissolving ammonium chloride in water
The reaction of thionyl chloride (SOCl2) with cobalt(II) sulfate heptahydrate
Mixing water and ammonium nitrate
Mixing water with potassium chloride
Reacting ethanoic acid with sodium carbonate
Photosynthesis (chlorophyll is used to react carbon dioxide plus water plus energy to make glucose and oxygen)
Endothermic Processes
These examples could be written as chemical reactions, but are more generally considered to be endothermic or heat-absorbing processes:
Melting ice cubes
Melting solid salts
Evaporating liquid water
Converting frost to water vapor (melting, boiling, and evaporation, in general, are endothermic processes
Making an anhydrous salt from a hydrate
Forming a cation from an atom in the gas phase
Splitting a gas molecule
Separating ion pairs
Cooking an egg
Baking bread
