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.

Please explain in a paragraph

When carrying out experiment in the laboratory to investigate physical changes, absolute measurement is usually not needed. For instance, one can just take a little sample of sodium chloride and dissolve it in water to demonstrate physical change. But for other experiments, such as the measurement of the catalase enzyme activity in a liver tissue. Careful measurements have to be made when preparing the chemicals that will be used in the experiment.
