The given semiconductor should be identified and after doping the produced semiconductor type should be determined. Concept Introduction: Semiconductor: The electrical conductivity of the substance increases when the temperature increases. In normal temperature conductivity of the substance is equal to insulator. N-type semiconductor: The host substance is doped by more valence electrons containing substance give n-type semiconductor. The conductivity of the host substance is increases when the valence electrons containing substance are doped. P-type semiconductor: The host substance is doped by less valence electrons containing substance give p-type semiconductor. Molar mass : The mole present in the gram of substance is called molar mass. Molar mass = Mass g mole ...... ( 1 )

b) Certain cyclic compounds are known to be conformationally similar to carbohydrates, although they are not
themselves carbohydrates. One example is Compound C shown below, which could be imagined as adopting
four possible conformations. In reality, however, only one of these is particularly stable. Circle the conformation
you expect to be the most stable, and provide an explanation to justify your choice. For your explanation to be
both convincing and correct, it must contain not only words, but also "cartoon" orbital drawings contrasting the
four structures.

How to measure distance and calculate rate
For the titration of a divalent metal ion (M2+) with EDTA, the stoichiometry of the reaction is typically:
1:1 (one mole of EDTA per mole of metal ion)
2:1 (two moles of EDTA per mole of metal ion)
1:2 (one mole of EDTA per two moles of metal ion)
None of the above
