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…

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…

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.

Using the mass spectrum, determine the chemical formula including any chlorine, bromine or nitrogen present. This compound does not contain any oxygen atoms. I need help on this problem, please!

Methods of Analysis Test #1: Polarity, or Effect of a charged rod on a stream of liquid: This test was used to determine the relative polarity of the unknown liquid. The liquid was allowed to run out of a buret and a charged rod was brought up next to the stream. The observations were reported as to whether or not the stream of liquid responded to the charged rod and to what degree. Try this at home with water and a plastic spoon. Rub the plastic spoon against a sweater and move it close to a small stream of water running out of your faucet! Test #2: Volatility, or Rate of Evaporation: A thermometer probe was wrapped with a strip of filter paper. This assembly was soaked in one of the liquids for one minute. The probe was removed, and the temperature change was monitored as the liquid evaporated. The results are given in Graph 1 below.

O GASES Jacqueline Solving for a gaseous reactant Combustion of hydrocarbons such as undecane (CH24) produces carbon dioxide, a "greenhouse gas." Greenhouse gases in the Earth's atmosphere can trap the Sun's heat, raising the average temperature of the Earth. For this reason there has been a great deal of international discussion about whether to regulate the production of carbon dioxide. 1. Write a balanced chemical equation, including physical state symbols, for the combustion of liquid undecane into gaseous carbon dioxide apd gaseous water. ロ ローロ 2. Suppose 0.430 kg of undecane are burned in air at a pressure of exactly 1 atm and a temperature of 20.0 °C. Calculate the volume of carbon dioxide gas that is produced. Round…

Which of the following statements are false for the time-of-flight mass spectrometer ? Light fragments travel faster than heavier fragments. A strong electric field is present in the tube by positioning a high-voltage metal grid in the path. Uses a magnetic field. Fragments are separated based on how fast they move through a drift tube. Signal is measured versus time, and then translated to a mass spectrum.
