An herbicide is found to contain only c, h, n, and cl. the complete combustion of a 100.0-mg sample of the herbicide in excess oxygen produces 83.16 ml of co2 and 73.30 ml of h2o vapor at stp. a separate analysis shows that the sample also contains 16.44 mg of cl. part a determine the percent composition of the substance.

Afisherman notices that his boat is moving up and down periodically without any horizontal motion, owing to waves on the surface of the water. it takes a time of 2.20 s for the boat to travel from its highest point to its lowest, a total distance of 0.670 m . the fisherman sees that the wave crests are spaced a horizontal distance of 5.80 m apart. (a) how much is the wavelength? (b) find the period of the wave. (c) how fast are the waves traveling? (d) what is the amplitude a of each wave?
