Molar Heat

Introduction
We have learned two kinds of molar fire up. One is breakup and the other one is neutralization. We have seen that a change in phase can be exothermic or endothermal and also seen that chemical reactions can absorb or assoil energy. Now it is time for molar change of dissolution.
First, Molar erupt of dissolution is when a solvent dissolves a solute, the particles of solvent afford apart to make room for the particles of solute. Since there are wanton chemical baffles that hold the particles of solvent and solute together, these bonds must be broken in order for the solution to occur. When the solution does happen, new bonds are create between particles of solvent and solute. All of this bond breaking and bond making means heat exchange. So the heat is fundamentally from breaking bond and rebuilding bond. And if the heat of the breaking bond is higher than the productions, it means exothermic. For the opposite is opposite.
Secondly, it is the molar heat of neutralization. The neutralization of an acid or a base is a chemical reaction that always involves the exchange of heat. However, since these are ionic molecules, the bonds broken and formed are ionic and will non be found in the table you consulted earlier. It still determines the heat exchange of the reaction empirically.




Finally, I and my teammate did a research laboratory experiment on these two kinds of molar heat, and try to generate out the change of the temperature and how much heat transferred from one to some other etc.
For this lab experiment consisting of 3 parts, we discovered the measure of thermal energy transferred through the dissolution with sodium hydroxide (NAOH) and then through the neutralization with hydrochloric acid (HCL). The final shout consisted of doing both a dissolution and neutralization together.
