Starting out in chemistry and looking for information to expand your knowledge? In this section, you will find the necessary basics and many interesting facts about chemistry!
The term “diffusion” describes the movement of energy or molecules/particles in a given medium as a result of their chaotic collisions with each other or with particles of the surrounding medium. Most often, we talk about diffusion in the context of molecular transfer caused by differences in concentration. Diffusion is a process commonly observed in […]
By definition, luminescence is the emission of light by cold objects, as opposed to incandescence, which is the emission of light by hot objects. Simply put, it is radiation of non-thermal origin. In molecular terms, it is a phenomenon resulting from the transition of molecules from an excited state to the basic state. As a […]
In the case of chemical reactions, complete conversion of substrates to products is observed only for a small part of them. The vast majority, including those occurring in our body, are reversible. For such processes, a state of chemical equilibrium is established. This is an extremely important concept in chemistry, which is associated with, for […]
As a nation, we can and should be proud of the fact that Poles have made a significant contribution to the development of so many scientific disciplines. One of the fields pioneered by our scientists is chemistry – prominent Polish chemists and their achievements are known all over the world. The discoveries of many of […]
All objects and phenomena surrounding us, existing and occurring independently of our will, are called matter. Every experimentally detectable form is a part of it. Existing objects constitute physical bodies, which in turn are called substances. It is a type of matter with a constant chemical composition that a given body consists of. For example, […]
Obtaining electricity from nuclear fission processes is undoubtedly an important aspect of modern power engineering. A nuclear reactor is a device in which a controlled nuclear reaction is carried out. Reactors are the main equipment of nuclear power plants where nuclear energy is converted into electricity. Reactors are also one of the propulsion elements of […]
Chemistry is an experimental science that requires understanding the laws and relationships between substances in the world. Some of them are commonly accepted assumptions aimed at ordering certain characteristics. Others, on the other hand, allow for a qualitative or quantitative assessment of the results of the reactions carried out.
Carbon is the most common element on Earth. It creates numerous bonds, mainly with hydrogen and oxygen. There are three known isotopes of carbon: 12C, 13C and 14C. The latter, due to its radioactive properties, is colloquially called radiocarbon. Its most important application is determining the age of geological formations and archaeological objects. In addition, […]
Looking at their structure, carboxylic acids are important organic compounds, and they are acyl derivatives. They are a kind of building materials for many derivatives, including esters and amides. In nature, we can find a whole range of various carboxylic acids, such as acetic acid CH3COOH, which is the basic compound of table vinegar, butyric […]
We fashion our Academy based on the needs of our users. We study their preferences and analyse the chemistry keywords through which they search for information on the Internet. Based on this data, we publish information and articles on a wide range of issues, which we classify into various chemistry categories. Looking for answers to questions related to organic or inorganic chemistry? Or maybe you want to learn more about organometallic chemistry or analytical chemistry? Check out what we have prepared for you! Keep up to date with the latest news from PCC Group Chemical Academy!
