Was this dissolving process endothermic or exothermic?

You are reading: “Was this dissolving process endothermic or exothermic?”. Let’s movsa.org learn more about Was this dissolving process endothermic or exothermic? in this article.


In Sam’s case, when ammonium nitrate was dissolved in water, the system absorbed heat from the surrounding, the flask, and thus the flask felt cold. This is an example of an endothermic reaction. In Julie’s case, when calcium chloride was dissolved in water, the system released heat into the surroundings, the flask, and thus the flask felt hot.

2. Is the dissolving reaction of NH4Cl endothermic or …

20/06/2020 · Answer and Explanation: Dissolving salt in water is endothermic. This means that when salt is dissolved in water the temperature of the solution is often a little lower than Is NaCl h2o endothermic? In NaCl+H2O, Na+ ions are liberated in an endothermic reaction. However when Na+ ions are added to water, the reaction is highly exothermic.

4. Exothermic and Endothermic Processes | Introduction to …

In the presence of water, a strong acid will dissociate quickly and release heat, so it is an exothermic reaction. Exothermic reaction In an exothermic reaction, the total energy of the products is less than the total energy of the reactants. Therefore, the change in enthalpy is negative, and heat is released to the surroundings.

Exothermic and Endothermic Processes. When physical or chemical changes occur, they are generally accompanied by a transfer of energy. The law of conservation of energy states that in any physical or chemical process, energy is neither created nor destroyed. In other words, the entire energy in the universe is conserved. In order to better understand the energy changes taking …
