Not obligatory; the dissolution of sodium, calcium, potassium chlorides are exothermic.
If a salt precipitates upon heating a concentrated solution, the heat of solution for this salt would be endothermic. This is because the process of dissolving the salt is absorbing heat from the surroundings, leading to a decrease in temperature and the precipitation of the salt.
Freezing is exothermic, as the substance that is freezing loses energy to its surroundings.
Yes. A wolf is endothermic, able to maintain its own body temperature. It is a mammal, and mammals and birds are endothermic. The term 'endothermic' is the biological term for an animal that is warm-blooded.
A duck is endothermic, able to maintain its own body temperature. It is a bird, and mammals and birds are endothermic. The term 'endothermic' is the biological term for an animal that is warm-blooded.
Endothermic salts are typically double salts that contain water molecules within their crystal structure. These salts require energy input to break the bonds holding the water molecules, resulting in an endothermic reaction. An example of this is hydrated copper(II) sulfate, which turns from blue to white when heated due to the loss of water molecules.
Yes, adding salt to ice is an endothermic reaction because it absorbs heat from the surroundings in order to melt the ice. The process of dissolving salt in water requires energy, which is taken from the surroundings, resulting in a decrease in temperature.

Endothermic reactions
Grinding up sea salt is a process that requires breaking the bonds between the salt particles, which would require energy input. Therefore, it is an endothermic reaction as it absorbs heat from the surrounding environment.
a:the dissolving of only salt A was endothermic b:the dissolving of only B was endothermic c:the dissolving of both salt a and A and salt B was endothermic d:the dissolving of salt A was exothermic and the dissolving of salt B was endhothermic
No. The dissolving of salt in water is an exothermic process because it releases energy in the form of heat.
When salt is introduced to water, it creates an endothermic reaction. This reaction creates heat, therefore speeding up the melting rate.

Freezing is exothermic, as the substance that is freezing loses energy to its surroundings.
Yes. A wolf is endothermic, able to maintain its own body temperature. It is a mammal, and mammals and birds are endothermic. The term 'endothermic' is the biological term for an animal that is warm-blooded.
When ammonium chloride dissolves in water, it is not a reaction at all, but only a dissolution. Since the solution formed feels cold, the dissolution is endothermic, absorbing heat from its surroundings.
All ENDOthermic reactions are of course ENDOthermic by themselves, aren't they?
