Fertilizer is sold in bags labelled with the amount of nitrogen (nn), phosphoric acid (p2o5p2o5), and potash (k2ok2o) present. the mixture of these nutrients varies from one type of fertilizer to the next. for example, a bag of vigoro ultra turf fertilizer contains 2929 pounds of nitrogen, 33 pounds of phosphoric acid, and 44 pounds of potash. another type of fertilizer, parker's premium starter, has 1818 pounds of nitrogen, 2525 pounds of phosphoric acid, and 66 pounds of potash per bag. determine the number of bags of each type required to yield a mixture containing 101101 pounds of nitrogen, 103103 pounds of phosphoric acid, and 2828 pounds of potash.

Why do the strengths of london (dispersion) forces generally increase with increasing molecular size? choose one: a. heavier atoms have stronger attractions for each other than lighter atoms. b. dispersion forces are all equal in magnitude; there is no size dependence. c. dispersion forces arise from the attraction between the nuclei of atoms, and larger molecules have larger nuclei. d. dispersion forces arise from dipoles caused by the electron distribution being distorted. larger molecules have more electrons and, therefore, more distortions and a bigger force. e. dispersion forces depend on distance. larger molecules are farther apart and so the forces are smaller.
