A bomb calorimetry, Or device offen of Combustion Content of goods. The Calorimeter temperature -In an experiment, a 0.4906g Sample of 1,9-nonaneda (Cat₂o O₂) is buined completely in a bomb calorimeter, is surrounded by 1.265 × 16³ g of water, During the combustion the from 26.88 to 29.59 °C. The heat 4,188 J 9 °C! Capacity of water is The heat capacity increases of the calorime ter was determined be 947,25, C! to а previous experiment Assuming that no energy is lost to the surroundings; Calculate the molar heat of combustion of 1,9- nonanediol based on these data, Calzoo (s) +130, (9) IOH, Ole)+9CO, (9) Cergy kJ/mol C Constant volume, is a the heat used to determine fuels and the energy Molar Heat of combustion=
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.
