Criminalist julie sandel is investigating a series of threatening notes written in pencil and sent to a local politician. a suspect is arrested and julie directs the suspect to prepare writing samples to compare to the writing on the notes. she has the suspect sit at a desk in an empty office and gives him a pen and a piece of paper. she begins to read one of the notes and asks the suspect to write the words she dictates. after reading about half a page, she stops, then dictates the same part of the note a second time for the suspect. at one point, the suspect indicates that he does not know how to spell one of the words, so julie spells it for him. after completing the task, julie takes the origi- nal notes and the dictated writing from the suspect to a document examiner. what mistakes, if any, did julie make?

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.)
