For some jobs, “good enough” is good enough. that’s sometimes true in chemistry. more often, though, careful planning, calculations, measurement, and laboratory work are necessary to get the desired result. imagine two tasks that would involve a chemical reaction of some sort. for one, measurement is not all that critical. for the other, careful stoichiometry and laboratory process is essential. identify and describe two tasks (projects, operations, devices, etc.) that differ in this way.
