Identify each statement as either describing the limit of detection (lod) or the limit of quantitation (loq). a) the signal is equal to the average signal of the blank plus three times the standard deviation of the signal from the blank. b) it is the minimum amount of analyte that produces a signal which can be measured with reasonable accuracy. c) the concentration is equal to three times the standard deviation of the signal from the blank divided by the slope of the calibration curve. d the concentration is equal to 10 times the standard deviation of the signal from the blank divided by the slope of the calibration curve. e) it is the minimum amount of analyte that produces a signal that is significantly different from the blank.

For a research project, a student decided to test the effect of the lead(ii) ion (pb2+) on the ability of salmon eggs to hatch. this ion was obtainable from the water‐soluble salt, lead(ii) nitrate, which the student decided to make by the following reaction. pbo(s) + 2 hno3(aq) → pb(no3)2(aq) + h2o losses of product for various reasons were expected, and a yield of 86.0% was expected. in order to have 5.00 g of product at this yield, how many grams of pbo should be reacted? (assume that sufficient nitric acid, hno3, would be used.)
