You want to determine the enthalpy change for the neutralization of HCI(aq). The equipment you are allowed to use are listed below: • safety goggles • lab coat • protective gloves • coffee cups (2) • styrofoam lid • thermometer • scale • stirring rod • beaker • 16-ml of 0.345 mol/L HCI(a) added to 42.6-ml of NaOH (aq) for a total volume which is equivalent to water (m) in the q equation a. Based on the equipment provided above, design a lab to determine the enthalpy change of neutralization of HCI(aq). Ensure you use numbered steps. When you carry out the experiment, you observe a temperature change of 3.80°C. b. Calculate the quantity of heat transferred to the calorimeter based upon the data provided.

Thermochemistry
Thermochemistry can be considered as a branch of thermodynamics that deals with the connections between warmth, work, and various types of energy, formed because of different synthetic and actual cycles. Thermochemistry describes the energy changes that occur as a result of reactions or chemical changes in a substance.
Exergonic Reaction
The term exergonic is derived from the Greek word in which ‘ergon’ means work and exergonic means ‘work outside’. Exergonic reactions releases work energy. Exergonic reactions are different from exothermic reactions, the one that releases only heat energy during the course of the reaction. So, exothermic reaction is one type of exergonic reaction. Exergonic reaction releases work energy in different forms like heat, light or sound. For example, a glow stick releases light making that an exergonic reaction and not an exothermic reaction since no heat is released. Even endothermic reactions at very high temperature are exergonic.
