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.

Can you store cuso4 in an aluminum container? explain your reasoning
mash [69]

We can store the copper sulphate solution in alumiun container, if cover on alumiun is present.

<h3>Can you store cuso4 in an aluminum container?</h3>

Aluminium is more reactive than copper so the Aluminium will displace copper sulphate from its solution by reacting with it but if there is cover on the aluminium then the alumium can't react with copper.

So we can store the copper sulphate solution in alumiun container.
