Noble gases are a very interesting group of elements, that all have relatively similar properties. The chemistry of these compounds is very similar. Under standard conditions (under temperature of 0°C, and pressure of 100 kPa) they are all colorless and odorless monoatomic gases with a very low chemical activity. Click to read more …
General chemistry is a science that is deeply incorporated in our everyday lives, but most of the people probably aren’t even aware of it being so. After reading the information in this article, you will think a bit more about this interesting science the next time you wash your hands, clean the barbecue after a party, or pour the detergent in the washing machine. Every one of the mentioned cases can serve as an great example for chemistry reactions that we witness often. Click to read more …
Water is one of the most important substances known to the science of chemistry. It is a ubiquitous chemical substance that is composed of two atoms of hydrogen and one atom of oxygen, and is essential for all life forms that are known at the moment. Water covers more than 70% of the Earth’s surface, mostly in form of oceans and seas. Click to read more …
In chemistry, compounds that change their color in relation to the amount of water that they contain in themselves are quite common and well known (often this water is called water of crystallization because it is incorporated in the crystal lattice). Among others, we’ll list the example of cobalt chloride. When it is completely dry it has a characteristic blue color, and when it absorbs enough water, the color changes from a dark blue to bright pink color. Click to read more …
The science of chemistry is a science that is deeply incorporated in our everyday lives, but most of the people are probably not aware of it being so. After reading this article, you will probably think a bit more about this science the next time you will hold a photograph in your hands, or take one with a camera. The occurences that were mentioned can serve as an excellent example for chemical processes that we witness often. Click to read more …
Chemistry is a important part of many engineering branches. Pyrotechnics is one of these branches, and in this article, we will mention and describe some of the basic but interesting facts related to energetic materials. An explosive material is a material that is more or less chemically stable, and can, by initiation, cause a sudden expansion of matter, that is often accompanied with the production of pressure and heat.

Mirror is an object with at least one polished, and because of that, specularly reflective sufrace. Mirrors are usually manufactured by applying a reflective coating to a suitable substrate. The most common substrate that is used today is glass, because of its transparency, ease of fabrication and rigidity. Click to read more …
Alkaline earth metals are truly a very interesting group of elements, that have relatively similar properties, as many other elements within the same group have. The chemistry of these compounds is very similar. The following elements form the mentioned group (also known as group 2 in the periodic table of elements): berlyllium (Be), magnesium (Mg), calcium (Ca), stroncium (Sr), barium (Ba) and radium (Ra).

There are many interesting groups of substances in the science of chemistry. The largest group of substances is based on a single element that we know as carbon. Since an entire branch of chemistry, known as organic chemistry is actually based on this element, in this article we will mostly write about carbon as a very interesting and also important chemical element.
