Fluorine-18 is a radioactive isotope that decays by positron emission to form oxygen-18 with a half-life of 109.7 min. (A positron is a particle with the mass of an electron and a single unit of positive charge; the equation is F 9 18 → O 18 8 + e + 1 0 Physicians use 18 F to study the brain by injecting a quantity of ?uoro-substituted glucose into the blood of a patient. The glucose accumulates in the regions where the brain is active and needs nourishment. (a) What is the rate constant for [lie decomposition of ?uorine-18? (b) If a sample of glucose containing radioactive fluorine-18 is injected into the blood, what percent of the radioactivity will remain after 5.59 h? (c) How long does it take for 99.99% of the 18 F to decay?

Hi!!
Please provide a solution that is handwritten.
this is an inorganic chemistry question please answer accordindly!!
its just one question with parts JUST ONE QUESTION with its parts spread out till part (g), please answer EACH part till the end and dont just provide wordy explanations wherever asked for structures, please DRAW DRAW them on a paper and post clearly!! answer the full question with all calculations step by step EACH PART CLEARLY please thanks!!
im reposting this please solve all parts and drawit not just word explanations!!
