Electric power is measured in watts (1 w = 1 j/s). about 95% of the power output of an incandescent bulb is converted to heat and 5% to light. if 12% of that light shines on your chemistry textbook, how many photons per second shine on the book from a 62 w bulb? (assume that the photons have a wavelength of 504 nm). enter a number in scientific notation (e. g. 1.23e12).

Some liquids can be distilled, but only at temperatures that are so high that it is impractical, or so high the compound decomposes. explain why distillation such compounds at significantly less than atmospheric pressure (some degree of vacuum) would solve this problem.
