Sulfur would be the answer
Answer: Potential energy is converted to kinetic energy and back again.
Explanation:At points 1 and 3, the pendulum stops moving, and its mechanical energy is purely potential. At point 2, the pendulum is moving the fastest, and its mechanical energy is purely kinetic. Therefore, as the pendulum moves from point 1 to point 3, its potential energy is first converted to kinetic energy, then back to potential.

Answer :
Option D) 2.50 X
Mol/(L s)
Explanation: While calculating the average reaction rate for the given reaction in terms of Cl;

.
using the rate equation which is;

![\frac{delta [Cl]}{delta t}](https://tex.z-dn.net/?f=%20%5Cfrac%7Bdelta%20%5BCl%5D%7D%7Bdelta%20t%7D%20)
=

=
2.50 X
Mol/(L s)
