Stoichiometric Calculations Involving Reactions/Solutions - Most chemical reactions are carried out in solutions. It is therefore important to know how to express the concentration of the substance in its solution. Most common ways of expressing concentration of any solute in a solution a..

The elements of the third period contain d-orbitals also in addition to s- and p-orbitals. The 3d-orbitals are comparable in energy to the 3s- and 3p-orbitals. These d-orbitals are also involved in the hybridization and they explain the geometries of molecules of elements of third period...
