CHEMISTRY GLOSSARY

Boltzmann equation    →   Boltzmannova jednadžba

Boltzmann equation is a statistical definition of entropy, given by

where S and k are the entropy and Boltzmann’s constant, respectively, and W is the probability of finding the system in a particular state.

chemical balance    →   kemijska ravnoteža

Chemical balance is a degree of reversible reaction in a closed system, when the forward and backward reaction happen at same rates and their effects annul each other, while the concentration of reactants and products stays the same.

chemical cleaning    →   kemijsko čišćenje

Chemical cleaning is a removal of fatty and other impurities combined with it from fabrics with the help of organic solvents.

chemical compound    →   kemijski spoj

Some substance is a compound only if it can be decomposed into two or more different substances by means of a chemical reaction. If two or more substances react, thus creating a new substance, that new substance is called a chemical compound.

chemical corrosion    →   kemijska korozija

Chemical corrosion is a damaging process of some materials with a chemical agent.

chemical element    →   kemijski element

Chemical element is a type of matter of which elementary matter is composed. Chemical element is composed of atoms with the same core charge.

chemical energy    →   kemijska energija

Chemical energy is the energy stored in substances and transferred during chemical reaction.

chemical engineering    →   kemijsko inženjerstvo

Chemical engineering is the branch of engineering that is concerned with the design, construction and operation of the plants and machinery used in industrial chemical processes.

chemical glass    →   kemijsko staklo

Chemical glass is a special, resilient glass used in production of chemical vessels; it is composed of quartz and boron, barium, zinc and aluminium oxides.

chemical kinetics    →   kemijska kinetika

Chemical kinetics is an area of chemistry that studies rates and mechanisms of chemical reactions.
