Most households in the town of Rapidsville get their drinking water from private wells that have been drilled into an aquifer. During the past decade, the water table in the aquifer has dropped. The town council of Rapidsville has recently requested proposals for projects that will help the aquifer to recharge with water. Which of the following project proposals is MOST likely to achieve the goal set by the town council? Group of answer choices

replacement of cement parking lots with gravel and tile lots

creation of a dam on the Rapidsville River to create a reservoir

installation of automatic sprinkler systems on city property

drilling of new wells to replace old wells on citizens’ property

Since the gas in your graduated cylinder is a mixture of butane and water vapor, you must determine the partial pressure of the butane, pbutane, alone. to do this, consult a reference and record the partial pressure of the water vapor, pwater, at the temperature you recorded. use the following formula to compute the partial pressure of the butane. pbutane = atmosphere - pwater use the following combined gas law formula and compute the volume that the butane sample will occupy at stp. (hint: convert both temperatures to kelvin.) pbutane x voriginal = pstandard x vfinal troom tstandard use the following ratio and proportion formula to determine the mass of butane needed to occupy a volume of 22.4 l at stp. grams of butane you used “x” grams of butane ml of butane corrected to stp = 22,400 ml compute the theoretical molar mass of butane based on its formula and the atomic masses on the periodic table. compare your experimental results from #3 to the theoretical value of #4, computing a percent error of your findings using this formula: % error = measured value - accepted value x 100 accepted value use the following ratio and proportion formula to determine the mass of butane needed to occupy a volume of 22.4 l at stp. need asap
