Molecule

link together to form molecules, which are the natural chemical units of matter. Molecules represent the smallest particle of a chemical compound which retains the characteristics and chemical properties of the compound. With the rare exception of certain single atom molecules, almost all molecules consist of two or more atoms linked together. An atom of the violently active metal sodium (Na) linked to an atom of the poisonous gas chlorine (Cl), for instance, gives one molecule of common salt…

Polarity means that the molecule has both a positively and negatively charged end. Water is called a universal solvent as it is able to dissolve so many common substances. Its polarity is responsible for its effectiveness in dissolving other polar molecules and ionic compounds, such as sugar and salt. This is very important, because for most biological reactions to occur, the reactants must…

Cronin explains that organic chemists use a long process to break down molecules by using reverse engineering. Being a chemist himself, he questioned whether there is a way to “make a real cool universal chemistry set”, in other words: can chemistry be “app-ed” to make medicine making more accessible. Cronin presents his idea of using a 3D printer to print the beakers and test tubes on one side and at the same time print the molecule on the other side and combine them together in a process he…

During the experiment, we removed the water from the hydrates using heat. A hydrate is a compound in which water molecules are chemically bonded to another element or compound. The removal of the water from a hydrate leaves the anhydrate. To find the amount of water in the hydrate, the hydrate’s mass can be measured. Then the water can be removed from the hydrate and the substance can be measured again. Finally, the subtraction of the mass of the substance after heating from the mass of the…

C2v. For simplicity, the macrocyclic, H6L, ligand can be divided into two (I and II) moieties which are repeated twice in the structure of the molecule. Figure 2 represents the structure of the two (I and II) moieties…

hydrochloric acid it means that it is probably an organic base. It was soluble in water because water is a polar molecular and since it’s polar, the molecules interact using hydrogen bonds and dipole-dipole intermolecular forces. This then leads to the fact that the partial negative and positive parts of the water molecule can break the bonds of ionic and polar molecules which causes them to dissolve within the…

In order to know more about nitrate, we actually must understand what a polyatomic ion is. A polyatomic is an ion which consist of molecules, thus, it may also be referred as a molecular ion. Two or more atoms covalently bond or share electron pairs with each other to make up a polyatomic ion. Once they have bonded, they become considered as a whole single ion. Moreover, it is known to have a charge, most polyatomic ions have a negative charge but there is an exception with a positive charge. In…

change the end in -ide. You're probably wondering what inorganic and organic compound are. An inorganic compound is any compound that is not organic while an organic compound is any member of large gaseous, liquid, or solid chemical compounds whose molecules contain carbon. A polyatomic ion compound are made up of two or more atoms bonded together and a metal. A binary compound is a chemical compound that contains exactly two different elements. These two differ because polyatomic are made up of…

For the volume to increase, the ‘cages’ of molecules has to be ‘inflated’, thereby making it bigger and occupy more space. To make the ‘cage’ bigger, the bond angle has to change and as such, FeO4 and PO4 tetrahedral will change as well. This changing of bond angle causes a tetrahedral distortion.…

Discussion of the Results and the Scientific Explanation The purpose of this experiment was to identify an unknown compound and discover its properties by devising experimental designs that enable for its identification (Cooper, 2009). Fifteen possible compounds were given, and a series of qualitative tests were used to eliminate the different possibilities and identify the specific unknown compound. These tests included a solubility test, which determines whether the compound is soluble in…
