You titrate a 25.00 mL solution of hydrochloric acid, HCl, with a 0.2015 M sodium hydroxide, NaOH, solution. The titration required 39.73 mL of the sodium hydroxide to reach the endpoint. What is the concentration (molarity) of the hydrochloric acid? HCI + NaOH →NaCl + H₂O Student work: 39.73 mL NaOH 25.00 mL HCI 1 L 1000 mL 1000 mL HCI 1 L HCI 0.0080055 mol HCI 0.02500 L HCI = 0.2015 mol NaOH 1 L NaOH 0.02500 mol 0.3202 M HCI 0.0080055 mol Read the feedback statements below and chose all that are applicable to the work shown. Choose one or more: The unit cancellation is not correct. The conversions to from mL to L do not need to be shown since they cancel out. The final answer has an incorrect number of s.f. (it should have 4 s.f.) The final answer has an incorrect number of s.f. (it should have 3 s.f.) Units do not cancel properly. The stoichiometry step to convert mol NaOH to mol HCI is not shown. All data collected, work shown, and final answer are recorded and shown correctly.

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.
