1、the structure of chemical thermodynamic is based on the first two laws of thermodynamics. starting from the first and second laws of thermodynamics, four equations called the “fundamental equations of gibbs ” can be derived. from these four, a multitude of equations, relating the thermodynamic properties of the thermodynamic system can be derived using relatively simple mathematics. this outlines the mathematical framework of chemical thermodynamics.
2、the study of materials is the joint concern of chemistry and physics. these two sciences are so closely related that no one can learn very much about either without considerable training in the other. in many of their applications it is hard to tell where the one science leaves off and the other begins.
3、an important part of the theory is that only one pair of electrons, with their spins paired, can be shared by two overlapping orbitals. this electron pair becomes concentrated in the region of overlap and helps “cement” the nuclei together, so the strength of the covalent bond --- and the extent to which the energy of the atoms is lowered --- is determined in part of the extent to which the orbitals overlap.
4、dalton’s atomic theory : 1) all matter is composed of tiny indivisible particles called atoms. 2) all atoms of an element are identical in mass and chemical properties, whereas atoms of different elements differ in mass and fundamental chemical properties. 3) a chemical compound is a substance that always contains the same atoms in the same ratio. 4) in chemical reactions, atoms from one or more compounds or elements redistribute or rearrange in relation to other atoms to form one or more new compounds. atoms themselves do not undergo a change of identity in chemical reactions.
5、inorganic chemistry deals with the synthesis and behavior of inorganic and organometallic compounds. this field covers all chemical compounds except most of the organic compounds (carbon-based compounds, usually containing c-h bonds), which are the subjects of organic chemistry. the distinction between the two disciplines is far from absolute, and there is much overlap, most importantly in the subdiscipline of organometallic chemistry. it has applications in every aspect of the chemical industry – including catalysis, materials science, pigments, surfactants, coatings, medicine, fuel, and agriculture.
6、although we cannot measure the total enthalpy, h, the good news is that we really do not need to know its value. we care only about what our system could do for us right here at a particular place on this planet. all we care about is by how much the enthalpy changes, because it is only this enthalpy change that is available to us. in other words, we really have no need for the absolute values of hfinal and hinitial. all we need is the difference, △h, and this is something we can measure.
