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.
No, freezing is exothermic as the water loses energy to its surroundings as it freezes.
Dissolution is generally exothermic.
Exothermic because the heat of formation is -566. Exo- is negative and Endo- is positive.
exothermic ? because energy released
The process of ice freezing is exothermic. When water molecules lose energy and come together to form a solid structure, they release heat into the surroundings. This heat release is what we feel as the temperature decreases and the water turns into ice.
good question endothermic. Ammonium chloride dissolves in water and makes it cold.
No, freezing is exothermic as the water loses energy to its surroundings as it freezes.
When it shocks its prey its exothermic. A simple way to remember this is Endo- = In and Exo- = Out.
Dissolution is generally exothermic.
exothermic ? because energy released
Exothermic because the heat of formation is -566. Exo- is negative and Endo- is positive.
HCl + NH3 --> NH4Cl is already exothermic Ammonium hydroxide is the solution of NH3 in water, giving the following exothermic reaction: [NH4OH]aq + H+aq + Cl-aq --> NH4+aq + H2Oliq + Cl-aq
The dissolution of ammonium chloride in water is an endothermic process, meaning it absorbs heat from its surroundings. This is because breaking the ionic bonds in solid ammonium chloride requires energy, resulting in a decrease in temperature.
Hydrochloric acid (HCl) and ammonia (NH3) react to form ammonium chloride (NH4Cl). This reaction is exothermic and produces white fumes of ammonium chloride.
The dissolution of ammonium chloride is an exothermic reaction because it releases energy in the form of heat. When ammonium chloride crystals are dissolved in water, the intermolecular forces between the ions and water molecules are stronger than the forces within the solid crystal lattice, resulting in the release of energy as heat.
Endothermic. That is why it is used in ice packs.
Only with very high heat. This compound can melt without decomposition.
