All of the following are common water pollutants that can be damaging to the environment except (2 points) select one: a. nitrogen from fertilizers. b. carbon dioxide from combustion. c. suspended solids from plowed fields. d. heat from industry and power plants.

Nitrogen (n), phosphorus (p), and potassium (k) are the main nutrients in plant fertilizers. according to an industry convention, the numbers on the label refer to the mass percents of n, p2o5, and k2o, in that order. calculate the n: p: k ratio of a 30: 10: 10 fertilizer in terms of moles of each element, and express it as x: y: 1.0.

There is a single path for electrons. the current decreases when additional resistors are added. the current will be the same in each resistor. these statements best describe a(n) circuit.
