19 protons, 20 neutrons and 18 electrons.
Explanation:
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)
Metamorphism would compare to a mineral that formed through evaporation
There are 600 hours.
explanation
each day has 24 hours and we want to know how much hours is equivalent to 25 days so we multiply 24 times 25 which is 600.
