Book Problems Ch 1: 27, 31, 77 Ch 2: 43, 53 Ch 4: 21, 30 Additional problems 1. A Boeing 747 jet can carry 586 passengers, and travel at a rate of 555 miles per hour. These massive machines burn 0.988 gallons of jet fuel per second! Given that the density of jet fuel is 0.81 g/mL, determine the pounds of fuel burned per mile per passenger. 2*. Explain why excessive exposure to high energy radiation can cause cancer. What are the differences between ionizing and non-ionizing radiation? 3. A certain laser emits monochromatic pulses. Approximately 1.25 x 1015 photons are emitted per second. A detection device is placed in front of the beam and measures the energy output over a span of 2 minutes. The device reports a total input energy of 75 mJ. Determine the wavelength of the emitted photons. 4. Imagine that you have the ability to see atoms. In your possession, you have a sample containing 100 Carbon atoms. If you selected one atom at random, what would you expect the mass (in amu) of that atom to be? What is the average mass of the sample? 5. Following the absorption of a single photon, a neutral Fluorine atom is ionized to F2+. Calculate the wavelength of the photon, in nm, to two significant figures. Use the ionization energy table in lecture 4. 6. Calculate the wavelengths of the photons emitted when excited hydrogen atoms undergo the following transition: n=5 n=1 7. Give the electron configuration of the 2nd excited state of Arsenic. 8. Write out the reactants and list any products for the single replacement reaction below, including phases. Make sure to balance. Refer to the activity table on pg 325. Also, include the redox reactions. If a reaction does not occur, write ‘no rxn’. Rubidium (s) + Sulfuric acid (aq) 9*. Provide the chemical name and chemical formula for bleach. Explain how it works. 10. Convert all names to formulas, and all formulas to names: 11. a.) Lithium phosphate b.) Aluminium carbonate c.) Ag2SO4 d.) WBr4 e.) Iron (III) sulfite f.) Ammonium perchlorate Provide acceptable sets of quantum numbers for the valence electrons of a Silicon atom.
