    Thermochemistry Lab Purpose: This lab taught procedures for determining heat of capacity of a calorimeter and measuring enthalpy of change for three reactions. It also enforced methods of analyzing data obtained through experimentation and calculating enthalpy. These procedures are used in the branch of thermodynamics known as thermochemistry which is the study of energy changes that accompany chemical reactions. Concepts from this lab can be used to determine the potential energy of a chemical

    Hess’ Law of Heat Summation Hess’ Law states that: "The enthalpy change for any reaction depends  on the products and reactants and is independent  of the pathway or the number of steps between  the reactant and product".  BASICALLY:    Hess’ Law states "the heat evolved or absorbed in     a chemical process is the same whether the process     takes place in one or in several steps"     ­­>This is also known as the "law of constant heat summation".       All it means is that no matter how many steps the chemical

    Thermochemistry Photo by: Arto Thermochemistry is the study of the heat released or absorbed as a result of chemical reactions. It is a branch of thermodynamics and is utilized by a wide range of scientists and engineers. For example‚ biochemists use thermochemistry to understand bioenergetics‚ whereas chemical engineers apply thermochemistry to design manufacturing plants. Chemical reactions involve the conversion of a set of substances collectively referred to as "reactants"

    Germain Henri Hess (August 7‚ 1802–November 30‚ 1850) was a Swiss-born Russian chemist and doctor who formulated Hess’s Law‚ an early principle of thermochemistry. Born in Geneva‚ Switzerland‚ his father was an artist and in 1805 moved the family to Russia to find work. Beginning in 1822‚ Hess studied medicine at the University of Tartu. He qualified as a physician in 1825. Hess turned to chemistry after a meeting with Jöns Jakob Berzelius‚ the famous Swedish chemist‚ and went to Stockholm University
