(a) Interpretation: The balance chemical equation for the reaction of an excess of O 2 with Ca needs to be determined. Concept introduction: There are different types of chemical reactions which occur between different compounds and follow different mechanism. Some common types of chemical reactions are synthesis reaction or combination reaction, displacement reaction, decomposition reaction, combustion reaction etc. The combustion reactions occur in the presence of oxygen to form oxides. These reactions are usually exothermic reactions.

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
