Explanation Oxygen sensors in advanced automobiles can detect oxygen content in the exhaust gases. The sensors are connected to computer systems which then make changes in air−fuel mixtures and spark timing to minimize air pollution and to increase efficiency in power. Scientist are developing screening procedures which will allow to bombard luggage in airport with high energy particles that will cause any substance such a explosives that contain high concentration of nitrogen to emit radiation that are characteristic of that substance. Organisms are very sensitive to the environment. Tissues from pineapple cores can be used to detect tiny amounts of hydrogen peroxide.

Students have asked these similar questions

1. Comment on the differences in measurements obtained on the same objects using the meter stick, ruler, and tape measure. How close are they to one another? 2. Which type of electronic balance gives you the most accurate mass? Why? 3. Comment on the differences found between the different volumetric measuring devices. How does the volume of the graduated cylinder compare to that obtained by the volumetric flask (i.e. are the volumes the same?) Which of these measuring devices gives the most accurate volume? Which of these measuring devices would you consider the easiest to work with?
