- On the following page, you will find the IR, 13C-NMR and ¹H-NMR for C6H12O. Determine the structure of the molecule. As you solve the structure, keep the following questions in mind: • What is the index of hydrogen deficiency for this formula? • Using the IR, what functional group(s) is (are) present in the molecule? What functional groups are missing? At what chemical shift range should look for corresponding peaks in the CNMR? In the HNMR? Are there peaks in those regions? • How many peaks are in the carbon NMR spectrum? How does it compare to the chemical formula? What might this tell you about the molecule? • How many peaks are in the proton NMR spectrum? How does it compare to the chemical formula? What might this tell you about the molecule? .Equations for the Standardization of the Na2S2O3 (aq): KIO3(aq) + 5KI(aq) + 3 H2SO4(aq) → 3 I2(aq) + 3 H2O(l) + 3K2SO4(aq) I2(aq) + 2 Na2S2O3(aq) → 2 NaI(aq) + Na2S4O6(aq) Equations for the Titration of the NaOCl (aq): NaOCl(aq) + H2O(l) + 2 KI(aq) → NaCl(aq) + 2 KOH(aq) + I2(aq) I2(aq) + 2 Na2S2O3(aq) → 2 NaI(aq) + Na2S4O6(aq)A chemist attached a NFPA symbol (illustrated below) on the bottle of a newly manufactured chemical.

- Determining Diet. One method for determining the amount of corn in early Native American diets is the stable isotope ratio analysis (SIRA) technique. As corn photosynthesizes, it concentrates the isotope carbon-13, whereas most other plants concentrate carbon-12. Overreliance on corn consumption can then be correlated with certain diseases, because corn lacks the essential amino acid lysine. Archaeologists use a mass spectrometer to separate the 12C and 13C isotopes in samples of human remains. Suppose you use a velocity selector to obtain singly ionized (missing one electron) atoms of speed 8.50 km /s, and you want to bend them within a uniform magnetic field in a semicircle of diameter 25.0 cm for the 12C. The measured masses of these isotopes are 1.99 * 10-26 kg (12C) and 2.16 * 10-26 kg (13C). (a) What strength of magnetic field is required? (b) What is the diameter of the 13C semicircle? (c) What is the separation of the 12C and 13C ions at the detector at the end of the…Chemistry (2023) Q1B2Help me complete the boxes
