Analysis: What is an ion? Describe what happens to the electrons in an atom when they absorb energy (from the flame)? Why does this produce a bright-line emission spectrum (rather than a continuous spectrum)? In terms of atomic structure, why does each metal ion produce a different color flame? What difficulties are there in identifying metal ions with a flame test? How could you improve the specific identification of the metal ions during a flame test? If it can be determined from the flame test results, what are the identities of the two unknown liquids? What might be some practical (and exciting) applications of metal containing compounds that create different colors of light while burning? Explain.
Sunburn is caused by ultraviolet UV radiation. Why does red light not cause sunburn?
6.72 LED bulbs offer a fairly new lighting alternative, and are becoming increasingly popular in home lighting. These bulbs combine excellent energy efficiency with the “warm” light and dimming ability of incandescent lights. Although LED bulbs are expensive, manufacturers claim that subsequent savings will more than offset the initial costs. Analyze the relative cost of incandescent versus LED lighting, assuming that the information in the table below is accurate. Are industry claims of cost savings justified? LED Incandescent Initial cost $4.00 $0.75 Electricity usage 8 watts 60 watts Electricity cost $0.04/kwh $0.04/kwh Lifetime 25,000 hours 1,500 hours
Question 17.a of 18 The work function (binding energy) is the energy that must be supplied to cause the release of an electron from a photoelectric material. The corresponding photon frequency is the threshold frequency. The higher the energy of the incident light, the more kinetic energy the electrons have in moving away from the surface. The work function for cesium (used in IR lamps) is equivalent to 202.6 kJ/mol photons. Use this information to calculate the energy, wavelength, and velocity of ejected electrons. What is the maximum wavelength (in nm) at which the electron can be removed from cesium? h = 6.626 x 10-34 J·s; c = 2.998 × 108 m/s8
Define the terms in the expression: ln k = ln A – Ea/RT
need it fast!! In a hydrogen atom, an electron loses energy from n = 5 to n = 2, a process that leads to some kind of “interaction” with electromagnetic radiation. What is the wavelength of this light in nanometers? Do NOT include a sign with this answer. Rydberg's constant is equal to -2.179 x 10-18 J. Planck's constant is equal to 6.626 x 10-34 Joule-seconds. The speed of light is 3.00 x 108 meters per second. Express exponents as number followed by E followed by the power (e.g., 7.34E-12).
Free electrons Metal The wavelength of A is less than B or C O The intensity of B is greater than C O The intensity of A is less than B or C The frequency of B is greater than C The frequency of A is less than B or C The wavelength B is greater than C Emitted free electrons Three different lasers (A, B and C), each with a different wavelength, is focused on the same alkali metal. Laser A light has no effect on the metal. Light from laser B and C both cause electrons to be released from the metal, but the light from laser B releases more electrons. Which of the following statements must be true?
