The solids Co, LiCl, SiC and CHI 3 have to be associated with the given sets of properties. Concept introduction: Types of solid Molecular solid Metallic solid Ionic solid Covalent network Molecular solid: A solid which consist of atoms or molecule thought intermolecular force. Metallic solid: The solid which consist of metal atom held together by metallic bonds. Metallic bonding is chemical bond formed by attraction between cation of metal and the surrounding sea of electrons. Ionic solid: A solid which consist of anions and cations held together by ionic bond (electrical attraction of opposite charges). Covalent network solid: A solid that involves atoms held together by great network or shackles by covalent bonds. Diamond and graphite are great example.

Definition Definition Connection between particles in a compound. Chemical bonds are the forces that hold the particles of a compound together. The stability of a chemical compound greatly depends on the nature and strength of the chemical bonding present in it. As the strength of the chemical bonding increases the stability of the compound also increases.

Draw the structures of these fragments.
For each reaction shown below follow the curved arrows to complete each equationby showing the structure of the products. Identify the acid, the base, the conjugated acid andconjugated base. Consutl the pKa table and choose the direciton theequilibrium goes. However show the curved arrows. Please explain if possible.
A molecule shows peaks at 1379, 1327, 1249, 739 cm-1. Draw a diagram of the energy levels for such a molecule. Draw arrows for the possible transitions that could occur for the molecule.
In the diagram imagine exciting an electron, what are its various options for getting back to the ground state?
What process would promote radiation less decay?
What do you expect for the lifetime of an electron in the T1 state?
Why is phosphorescence emission weak in most substances?
What could you do to a sample to enhance the likelihood that phosphorescence would occur over radiationless decay?
