Which of these activities might involve a chemist? question options: measuring the motions of a planet determining the fat content in a candy bar determining the air resistance on a moving car determining an organism's role in an ecosystem?

Answer;

Determining the fat content in a candy bar

Explanation;

-All chemists work indoors in laboratories and other controlled environments conducive to compromised research. They work with various types of scientific equipment, such as spectrometers and chromatographs, which allow the scientists to examine and evaluate chemicals and their compounds at a microscopic level.

-Most chemists operate in two worlds of work. One is the macroscopic world that you see, feel, and touch. Chemists also operate in the microscopic world that you can’t directly see, feel, or touch.

Determining the fat content in a candy bar

Explanation:

took the test

5 w for 1hr = 5x60x60 joules=300x60=3000x6=18,000j as total energy conversion. efficiency of bulb needed for radiant to thermal within 18000
