HW RTE 3

True or False 1. Gamma radiation is stronger than infared radiation because it has a much lower frequency. 2. A blue shirt appears blue because the fabric is dyed with a color that absorbs all of the blue light. 3. A solution that appears orange will absorb light at the 450-490nm range. 4. UV-Vis spectroscopy is necessary for the analysis of organic compound because most organic compounds are colored green in the presence of an extracting solvent. 5. The spectrophotometer is able to detect and report absorbance values of a compound based on the compound's ability to absorb radiation or emit radiation. 6. A common electronic transition for an organic compound is the electron shifting from a bonding orbital to a nonbonding orbital. 7. UV-Vis spectroscopy normally reports data in the form of bands rather than single peaks because of overlapping electronic transitions that are being recorded by the detector. 8. When using linear regression to translate absorption data using Beer's law,…

A 0.1860 g rock sample containing an unknown amount of Ca was dissolved in HCI and diluted to 100.0 mL. Aliquots of 5.00 mL from this solution were added to different volumes of a 2.08 µg/mL. Ca standard solution and diluted to 200.0 mL. The emission intensity of these solutions was measured using atomic emission spectroscopy. The results are shown in the table. Unknown volume (mL) Standard volume (mL) Final volume (mL) Emission Intensity 0.00 200.0 5.00 200.0 10.00 200.0 15.00 200.0 20.00 200.0 Find the weight percent of Ca in the rock sample and its uncertainty using the method of standard additions. weight percent: 5.00 5.00 5.00 5.00 5.00 8.27 x10-5 Incorrect % Ca .03 Incorrect 227.0 413.0 637.0 831.01 1021.0
