An organic compound was synthesized in the laboratory. The compound is known to contain three functional groups - an alcohol, an alkene, and an ester. Using IR spectroscopy, a broad peak was observed in the region between 3200-3400 cm^-1, which indicates the presence of the alcohol group. However, two different peaks were observed in the region between 1640-1680 cm^-1, which could correspond to either the alkene or ester group. Using other spectroscopic techniques such as NMR and mass spectrometry, determine the structure of the compound and identify which peak corresponds to the alkene or ester functional group.

A chemistry student needs to determine the percentage of calcium carbonate (CaCO3) present in a mixture of calcium carbonate and calcium phosphate. The student has the following information: A 1.00-gram sample of the mixture was dissolved and reacted with excess hydrochloric acid (HCl), producing 0.236 grams of carbon dioxide (CO2) gas. The balanced chemical equation for the reaction is: CaCO3 + 2HCl → CaCl2 + CO2 + H2O. The student also knows that the molecular weight of CaCO3 is 100.09 g/mol and that of Ca3(PO4)2 is 310.18 g/mol. What is the percentage of calcium carbonate in the mixture?
