None Is it possible to use spectroscopic techniques to confirm both 4 He and 3 He in a sample of helium? Think about a singly -ionized atom He and select an electronic transition of this hydronic atom that is seen in the visible range). Compute theresolution (absolute and relative) that instrumentation has to provide to distinguish the two isotopes and to allowquantitative (!) determination of content.

An exploration of any one application of Spectroscopy (Absorption or Emission), Mass Spectrometry (MS) - (ANY kind of mass spec) Pick one location/project/bit of research where the data is used and explore. Discuss on what is measured (what instrument) and why and how. You don't have to fully teach the instrument but spend a paragraph giving the very basics of what is measured and how. And discuss the application you discovered - just find a place the measurement is used and explain what they do - what they measure and when it tells them.
The velocity selector in the problem prior to this one is used in a mass spectrometer. Protons(with zero neutrons) are the most common hydrogen nuclei. Some hydrogen isotopes, however, haveeither one or two neutrons in addition to the proton. If a beam of hydrogen nuclei is shot into amagnetic eld of strength 2.0T and the nuclei do a u-turn after which they strike a detector, how farapart will the three isotopes be on the detector surface? Assume both protons and neutrons have amass of 1:67 10?27kg and e = 1:60 10?19C.Cont.

Potentially Useful Information Spectrochemical Series: | < Br < SCN¯ < Cl° < NO3¯ < F° < OH° < C2O4²¯ ~ H2O < NCS° < NH3 < en < PPH3 く A student has three test tubes containing a metal (M) nitrate solution M(NO3)2 (aq) (where "M" represents a generic transition metal). The student adds aqueous ammonia (NH3) to one test tube, aqueous hydrochloric acid (HCI) to the second tube, and nothing more to the third tube, but forgets to label the tubes. After this, one test tube contains a red solution, one an orange solution, and one a yellow solution. Note: This metal, M, would follow the same rules that we used for Cu(II), Ni(II), and Co(II). The Jahn-Teller Effect does not apply. Complete each statement or answer each question below about the solutions in the three test tubes. The aqua complex causes less splitting of the d orbitals of the metal than the... ammonia complex. O chloro complex.
2. ] You make 150.0 mL of a copper(II) sulfate solution but forget to cover it before leaving for the day. The next class, you measure the volume and find that you only have 132.0 mL remaining. You didn’t record the initial concentration, but you measure the absorbance of the remaining solution at 620 nm and find that it is 0.386. You also construct the following calibration curve for CuSO4: Standard solution Abs620 0.50 M 0.424 0.40 M 0.336 0.30 M 0.247 0.20 M 0.159 (refer to image) a. What is the value for k (in Beer’s Law)? Provide a calculation or graph to support your answer. b. What is the concentration of the (remaining) solution? c. What was the concentration of the original solution from the first class? d. If you removed 7.5 mL from the 132.0 mL solution in the process of measuring the absorbance, how much water should you add to obtain the original concentration that you solved for in part (c)?
