Assume ^35^Cl_2_ is a harmonic oscillator( it is slightly anharmonic). If K=329 N/m compute the zero-point energy for this molecule. ^35^Cl= 34.9688g/mol.
Addition to double bonds, oxidation of double bonds - Draw the structure/structures for the major organic product/products formed when 1-methylcyclohexene reacts
A 13.386 g aliquot of this solution is then titrated with 0.1052 M HCl. It required 30.21 mL of the HCl solution to reach the methyl red endpoint. Calculate the weight percent NH3 in the aqueous waste.
By Solving this problem student is able to understand how to calculate theoretical and percent yields in an experiment - determine theoretical and percent yields for this experiment.
