Answer question 1

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…

21. ADLC Assignment Booklet A3 Decide whether each statement is true (T) or false (F). Place your answer in the blank space given. Scientific theory states that the atoms in today's plastics were parts of microscopic plants and animals that lived in the oceans millions of years ago. b. Molecules of gasoline have more carbon atoms than do molecules of diesel fuel. c. Subjecting large molecules to cracking is useful because smaller molecules are manipulated more easily in a reaction to produce a desired product. d. Unsaturated compounds form during hydrocarbon cracking because too many hydrogen atoms are available for the number of carbon atoms.

Introduction Home Depot's market research shows that they can sell 20-lb. bags of ammonium phosphate, a common fertilizer with the chemical formula (NH4)3PO4, for $9.99/bag. This price has been marked up 6% from the wholesale price that they pay to the manufacturer. You decide to use your knowledge of chemistry to produce your own ammonium phosphate and sell it to Home Depot at 5¢ below the wholesale price. You contact a packager, who agrees to package your product for 29¢ per bag. Ammonium phosphate is produced from ammonia (NH3) and phosphoric acid (H,PO4). Ammonia, in turn, can be produced at a 50% yield via the Haber process, using a mixture of hydrogen (H2) and nitrogen (N2) gases with an iron catalyst. Phosphoric acid is obtained from a naturally occurring mineral called fluorapatite, Cas(PO4)3F, by the following process: fluoroapatite is mixed with silica sand (SiO2) and coke (elemental carbon, C) in an electric furnace. The products are carbon monoxide (CO), tetrafluorosilane…
