Water dissociation, the breaking of water molecules into hydrogen and hydroxide ions, is an endothermic process requiring energy input. This is because breaking the chemical bonds within the water molecule requires energy to overcome the attraction between the hydrogen and oxygen atoms.

Is dissociation of ammonium chloride endothermic or exothermic?
The dissociation of ammonium chloride is endothermic because energy is required to break the bonds holding the ammonium ion (NH4+) and chloride ion (Cl-) together. This process absorbs heat from the surroundings, making it endothermic.
Is base an endothermic or an exothermic?
Base dissociation is an endothermic process, meaning that it requires energy in the form of heat to occur. The energy is needed to break the bonds within the base molecule and allow it to dissociate into ions.
When clothes are drying is it an endothermic or an exothermic reaction?
The process of clothes drying is not a chemical reaction, so it is neither endothermic nor exothermic. It is a physical process where water evaporates from the fabric due to heat energy, resulting in the drying of the clothes.
When sodium hydroxide is dissolved in water the temperature of the water increases. Is this endothermic or exothermic?
This process is exothermic because it releases heat energy into the surroundings.
Is the dissolving of sodium chloride in water endothermic or exothermic reaction?
The dissolving of sodium chloride in water is an exothermic reaction because it releases energy in the form of heat.
Is dissociation of ammonium chloride endothermic or exothermic?
The dissociation of ammonium chloride is endothermic because energy is required to break the bonds holding the ammonium ion (NH4+) and chloride ion (Cl-) together. This process absorbs heat from the surroundings, making it endothermic.
Is ammonium endo or exothermic?
endothermic but don't know why? As AN crystals are formed the reaction is exothermic. Endothermic when it melts back with water. This is the reason AN is used in cold packs.
Is the formation of water endothermic or exothermic?
The process is endothermic because the water is absorbing heat from the kettle. When energy (heat) is released as steam this is exothermic.
Is Alka Seltzer in water a endothermic or exothermic reaction?
The dissolution is endothermic.
Is base an endothermic or an exothermic?
Base dissociation is an endothermic process, meaning that it requires energy in the form of heat to occur. The energy is needed to break the bonds within the base molecule and allow it to dissociate into ions.
A puddle of water evaporates is an example of exothermic or endothermic?
Evaporation is an endothermic process.
Is freeezing endothermic or exothermic?
Freezing is exothermic, as the substance that is freezing loses energy to its surroundings.
When clothes are drying is it an endothermic or an exothermic reaction?
The process of clothes drying is not a chemical reaction, so it is neither endothermic nor exothermic. It is a physical process where water evaporates from the fabric due to heat energy, resulting in the drying of the clothes.
When sodium hydroxide is dissolved in water the temperature of the water increases. Is this endothermic or exothermic?
This process is exothermic because it releases heat energy into the surroundings.
Is the dissolving of sodium chloride in water endothermic or exothermic reaction?
The dissolving of sodium chloride in water is an exothermic reaction because it releases energy in the form of heat.
Is barium hydroxide endothermic or exothermic?
The dissolution of barium hydroxide in water is exothermic, releasing heat as it forms a solution.
Is water vapor condensing on a glass exothermic or endothermic?
Steam itself is not endothermic or exothermic - only chemical reactions can be labelled as exothermic or endothermic the reaction whithin the steam can only be exothermic or endothermic
