Document Summary
True/false problems: water is a homogenous mixture. Mixing a small amount of alcohol in water and stirring produces a heterogenous mixture. Multiple choice problems: the speed of light is 3. 0 x 108 m/s. One isotope has an abundance of 57. 3% and an isotopic mass of. __ au + __ nacn + __ o2 + __ h2o __ naau(cn)2 + __ naoh: 1, 3, 2, 4, 1, 4, 3, 2, 3, 1. The correct set of stoichiometric coefficients, respectively, for the balanced reaction is: 3 6 6 3 4, 3 2 1 2 2, 1 2 2 1 1, 1 2 1 2 4, 2 1 2 2 2. 3: calculate the wavelength in nanometers for a bullet weighing 5. 0 g and traveling at. 400 m/sec: 3. 3 x 10-34 m, 5. 8 x 10-19 m, 1. 5 x 10-38 m, 3. 0 x 1033 m, 3. 3 x 10-37 m, most of the light emitted by excited mercury atoms has wavelengths of 185, 254, 365,
