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?
the answer is true trust me i got this answer wrong my dumb self chose f.
oxidation or combustion
5o₂ + c₃h₈ ⟶ 3co₂ + 4h₂o
you could call this an oxidation reaction, because the propane is reacting with oxygen.
you could also call this a combustion, because the reaction is so fast that the propane burns with a flame.
hope this !
