A hydrogen atom in an excited state can be ionized with less energy than when it is in its ground state. What is n for a hydroge
Molodets [167]

Explanation:

It is known that formula for the ionization energy of hydrogen atom is as follows.

               E = \frac{13.6 eV}{n^{2}}

or,          n = \sqrt{\frac{13.6}{E}}

The value of energy is given as 0.544 eV. Therefore, we will calculate the value of n as follows.

                   n = \sqrt{\frac{13.6}{E}}

                      = \sqrt{\frac{13.6}{0.544 eV}}

                      = 5

Thus, we can conclude that n equals to 5 for a hydrogen atom if 0.544 eV of energy can ionize it.

Kernels of corn are heated and become popcorn. Why is this a chemical change?
goldfiish [28.3K]

Answer:

When popcorn is popped, liquid inside the kernel is changed to steam. Pressure from the steam builds up inside the kernel. When the pressure reached a critical stage the kernel pops turning itself inside out. This is a physical change.
