a 2.00g sample of limestone was dissolved in hydrochloric acid and all the calcium present in the sample was converted to ca2 (aq). excess ammonium oxalate solution, (nh4)2c2o4(aq), was added to the solution to precipitate the calcium ions as calcium oxalate, cac2o4(s). the precipitate was filtered, dried and weighed to a constant mass of 2.43g. determine the percentage by mass of calcium in the limestone sample. when the coffee collective purchases advertisements on the radio, it does so with the goal of informing its dog-loving coffee drinkers of its new patio. this action characterizes which step of creating an advertising campaign? i can not figure out this question to save my life n iv infusion of dextrose 5% in normal saline (d5ns) 1,000 ml with oxytocin (pitocin) 20 units is prescibed for a client to control postpartum bleeding. the solution is to be administered at a rate of 2 mu/minute. how many ml/hour should the nurse program the infusion pump? calculate the maximum sustainable yield for a population whose carrying capacity (k) is 80,000 and whose per capita rate of growth (r) is 0.2. solve the system if x = 2y + 3 and 4x - 5y = 9 european flycatchers feed caterpillars to their hatchlings. graph 1 shows the average dates of hatching and fledging (leaving the nest), and the biomass of the caterpillars between early may (when flycatcher young hatch) and june (when fledging of young occurs). the figure presents two graphs of curves in two coordinate planes. one graph is above the other, and the graphs are related by dates indicated on the horizontal axes. a vertical line runs through the two graphs and is labeled with the date may twenty eighth. the graphs are described as follows. the upper graph consists of curves representing the distribution of flycatcher hatching and fledging dates and hatchling food needs over a time period. the horizontal axis has no label, and the dates may fifteenth and june second are indicated along it. the vertical axis is labeled frequency, and no numbers are indicated along it, although it ends in an arrowhead. the first curve, labeled date of hatching, is a bell curve which begins on the horizontal axis to the left of may fifteenth, peaks at may fifteenth, and ends on the horizontal axis to the right of may fifteenth but to the left of may twenty eighth. the second curve, labeled date of fledging, is a bell curve which begins on the horizontal axis to the right of may twenty eighth but to the left of june second, peaks at june second at the same height as the first curve, and ends on the horizontal axis to the right of june second. a third bell curve that is broader than the other two curves begins on the horizontal axis immediately before may fifteenth, peaks at may twenty eighth at the same height as the other two curves, and ends on the horizontal axis immediately to the right of june second. this broader curve is labeled hatchling food needs. the lower graph consists of a curve representing the biomass of caterpillars over the same time frame as in the upper graph. the horizontal axis has no label, and the date may twenty eighth is midway along it. the vertical axis is labeled biomass of caterpillars, and no numbers are indicated along it, although it ends in an arrowhead. the curve is a bell curve which begins on the horizontal axis immediately before may fifteenth, peaks at may twenty eight, and ends on the horizontal axis at immediately before june second. the curve has approximately the same dimensions as the hatchling food needs curve of the upper graph. the beginning of the curve is labeled hatching, the peak is labeled peak mass, and the end of the curve is labeled pupae. graph 1. comparison of european flycatcher hatching and fledging dates and caterpillar biomass based on the data, scientists claim that the reproductive behavior of european flycatchers is influenced by the availability of energy sources. which of the following statements best justifies this claim? The triangle below is equilateral. Find the length of side x to the nearesttenth. use the reaction equilibria below to find the k value for the dissociation of the ammonium cation to ammonia and h . if you eat a candy bar, sugar enters your digestive system. some of that sugar eventually leaves the body through the urinary system. where is the body's last chance to take the sugar and recirculate it into the bloodstream for use by cells before it is excreted as urine? Which aspect of the federal reserve system helps establish its independence from the government?A. Appointment of the Board of Governors by the presidentB. Its division into 12 Federal Reserve DistrictsC. Ownership of Federal Reserve System by member banksD.

The following list displays determinants of demand, which are the factors that affect the quantity of donuts consumers want to buy at a given price: price of a related good (complement or substitute), income of consumers, tastes of consumers, number of consumers, expectations of consumers. A water tank holds 675 gallons but is leaking at a rate of 4 gallons per week. A second water tank holds 900 gallons but is leaking at a rate of 7 gallons per week. After how many weeks will the amount of water in the two tanks be the same? How does the weight on a bicycle affects the force required to affect its motion?
