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.

Some lasics regarding Chemical Elements
A Chemical element found on the Perlodic Table of Elements (found on the Inside cover of your
text) isa pure substance which cannot be decomposed by chemical change.
The names of Elements are often abbrevlated to slmplify formoulas ustng these elements. These
abbreviations are refened to u chemical symbols. For Hydrogen, the symbol "H', for Onygen, "O,
and for Carbon, "C. Sometimes two letters are necessary to distingutsh bebween two or more
elements when the names of the elements begin with the sume letter. For Example Ca for Caldum.
Cr for Chromlum, Co for Cobalt, Cl for Chlorine, etc. No symbols contain more than two letters and
the first letter is always capitalized. Some symbolk are abbrevlations of Latin names ofelements (Le.
Fe for Iron; Latin, ferrum).
Each Element has an atomic number and an atomic welght. The welght is in relative ternos as an atom
of exch element is extremely small. As an example Hydrogen, "H has the atomic number of 1and
10 stomic welght of1.008, Calclamm has the atomic number of 20, with an atomic weight of 40.00.
One atom of čalaum welghs approsdmately 40 times that of Hydrogen.
The following is a list of Elements commonly found in the sol or atmospbere and utlized by plants
for their growth proceses. From the Periodic Table in your text, look up the Chemical Symbol, the
atomic number and the atomic welght.
