Which best describes a chemical reaction

Work is defined as the use of force to move on object in the direction of the force and is equal to the forced times the distance object moved. How do energy and power related to work?

The quantum mechanical approach to atomic structure permits the calculation of 1. the most probable distance between any two specified electrons. 2. a region about the nucleus in which an electron of specified energy will probably be found. 3.

While performing an experiment to establish relationship between weight of a rectangular wooden block lying on a horizontal table and the minimum force required to just move it using a spring balance, a student calculated the minimum force required
