m/s² aka meter per second squared.
acceleration = change in velocity/time
= distance/time

=m/s^2
Answer : The ratio of 
to 
is, 
Solution : Given,
= 0.21 atm
The given equilibrium reaction is,
The expression of 
will be,
Now put all the given values in this expression, we get:
Therefore, the ratio of to is,
Answer:
Isotopes are basically atoms of an element that have an unequal number of neutrons and protons. Of course the proton number remains the same, but the neutron number either decreases or increases, which leads to an overall change in mass. However, no chemical properties of the atom/element are changed as the electrons are the same number and do not react. In regards to Helium 4, the original number of neutrons in Helium is 2, and protons 2 as well. We see an equal number of neutrons and protons, hence an unchanged mass, and the element is <em>not</em> an isotope.
There are 9 orbitals in the third energy level and 25 orbitals in the fifth energy level.
