student found a bottle of unknown origin in the basement of an "CAUTION—contains С₁H₁O.” No other A old house. The bottle was labelled information was given, but inside the bottle were some white crystals. The student took the bottle to a chemistry laboratory, where she analyzed the crystals with the help of the laboratory staff. C₁2H₁6O reacted with Br₂ in CCl4 adding one mole of Br, and forming C₁₂H₁OB2₂. When a sample of C₁₂H₂O was reacted with O3 followed by Zn/H₂O, two different samples, J and K, were obtained. Compound J had a molecular formula of C.HgO₂, and its NMR is shown below. Compound K had a molecular formula of C₂H₂O, and it could be oxidized to compound L, with a molecular formula of C₂H₂O₂. The IR spectrum of L showed a very wide, strong band centred around 3000 cm*¹. The NMR spectrum of L showed only two different absorptions: a doublet (6H) at 0.9 ppm and a septet (1H) at 3.6 ppm. There was also a singlet (1H) off the scale at 11.8 ppm. students, deduce possible…
About Gravity, tick only the incorrect alternative(s), choose one or more: a) In gravimetric analysis, the mass of a given product is used to calculate the amount of analyte present in the original sample. b) Crystallization is a process that takes place in two phases: nucleation and particle growth. In nucleation, it involves adding more than one molecule to the crystallization nucleus to form a crystal. And in particle growth, the molecules in the solution randomly clump together, forming small aggregates. c) Impurities are known as co-precipitate, that is, the impurity is precipitated together with the desired product. d) Absorbed impurities are bonded to the surface of a crystal. Adsorbed impurities (which are inside the crystal) are classified as inclusions or occlusions. e) We can relate the mass of a gravimetric precipitate to the amount of original analyte. The general method is to relate the number of moles of products to the number of moles of reactant.

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.
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…
