Onanono100 Now we will mix two soluble liquids, water and ethanol and determine the final temperature. This time, the answer will not be the same as in Question 2 and 3. Try to set this up as an algebra problem (with variables) before you plug in numbers. Suppose you mix 25.0 mL of ethanol at 15°C with 35.0 mL of water at 68°C. What's the density of the ethanol is 0.79 g/mL at both temperatures and the heat capacity density of water is 1.00 g/mL at both temperatures and that the heat capacity of water is 4.18 J/g °C. the final temperature of the ethanol/water solution? Assume is 2.46 J/g °C at all liquid temperatures. Assume the of ethanol
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.
