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.

How many dimes could you trade for 360 pesos? $1 = 1500 pesos.

sveta [45]

Answer:

The correct option is (d).

Explanation:

It is given that,

1$ = 1500 pesos

We need to convert 360 pesos into dimes

We can convert 360 pesos to dollars as follows:

$360\ \text{pesos}=\$\dfrac{1}{1500}\times 360\\\\=$0.24$

360 pesos is equal to $0.24

Also, 1 dollar = 10 dimes

We can covert 0.24 dollar to dimes as follows :

0.24 dollar = 10 × 0.24 dimes

0.24 dollar = 2.4 dimes

360 pesos = 2.4 dimes
