Document Summary

Number of moles na = number of particles (atoms, molecules, ions, ect) Bronsted lowry theory: acid donates a proton and base accepts a proton. Lewis theory: acid accepts an electron pair and base donates an electron pair ph = -log10[h+] poh = -log10[oh-] Speed of light = c h = planck constant (6. 6260696 x 10-34 js. Light is a stream of photons that can behave as waves or as particles. Energy of light can be absorbed or emitted only as small discrete portions (energies of individual photons) The energy of each photon is determined by its frequency (or wavelength) Electrons emit light when it falls from higher to lower energy level. Lyman n = 1, ultra violent region of the spectrum. Balmer n = 2, visible region of the spectrum. Paschen n = 3, infrared region of the spectrum (include more on theories) Explains position of the lines in emission spectrum, as well as the balmer,
