A sample of ascorbic acid (vitamin C) is synthesized in the laboratory. It contains 1.50 g of carbon and 2.00 g of oxygen. Another sample of ascorbic acid isolated from citrus fruits contains 6.35 g of carbon. How many grams of oxygen does it contain? Which law are you assuming in answering this question?
Waves Electromagnetic Energy- electric and magnetic fields whose intensities oscillate over time Wavelength- distance between two crest or between two troughs (max/ mins a waves) unit= nanometer (nm) Frequency- number of crest that pass through a certain point in 1.00 second. Unit = hertz (Hz) *wavelength and frequency are inversely related= as wavelength increases, frequency decreases Quantum Theory- light is composed of particles (photons). Energy of a photon is proportional to its frequency, not intensity (brightness) Ephoton= hu U= frequency of the photon H= Plauck's constant (6.63 x 10^-34) Photoelectric Effect- photons of light can cause metal to lose electrons, but this only happens if the light has a certain minimum frequency (aka t
