a Typical calibration curve for emission spectroscope(such as ICP or fluorescence) is linear at low analyte concentrations, when the x-axis is concentrations and the Y-axis is detector response. the detector response is directly proportional to the number of detected photons.
a) Explain why construction of a linear calibration curve for emission spectroscope does not require any logarithmic data manipulation(as is required for absorption spectroscope?
for the isoelectronic series vco6- crco6 and mnco6 would you expect the energy of metal to ligand charge-transfer bands
a certain protein was found to contain 0.639% zinc by mass. Determine the minimum molecular mass of the protein.
Draw the structure of the product that is formed when 1-pentyne undergoes reaction with two equivalents of HCl.
