(a) Interpretation: The average number of people entering the store per for the 5- day period is to be calculated. Concept introduction: Scientific notation is used to write large numbers by shifting the decimal point. It is expressed as the product of a decimal term and the power of 10 . Significant figures are used to express a measurement into a correct number in scientific notation. The significant figures reflect the closeness of measured values to the standard values.

Part IV. C6H5 CH2CH2OH is an aromatic compound which was subjected to Electron Ionization - mass
spectrometry (El-MS) analysis. Prominent m/2 values: m/2 = 104 and m/2 = 9) was obtained.
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?
