How does the composition of the nucleus change during fission, fusion, and radioactive decay?

1 answer:

3 0

Fusion, fission, and radioactive decays of unstable nuclei, involve release or absorption of energy. The total number of neutrons plus protons does not change in any nuclear process. are not conserved, but the total number of protons plus neutrons is conserved.

Where would you have the least weight?

Vikki [24]

In a place with no gravity

Explanation:

Weight is a force exerted by a body in the presence of gravity.

Weight = mass x gravity

Without gravity, there is no force of weight. The more the gravity, the more the weight of a body.

A body will experience weightlessness in a place without no gravity.

Therefore, one will experience the least weight in a place without the pull of gravity.

8. Sulfur has a first ionization energy of 1000 kJ/mol. Photons of what frequency are required to ionize one mole of Sulfur?

Lynna [10]

Answer:

the frequency of photons $v = 1.509\times10^{39}Hz$

Explanation:

Given: first ionization energy of 1000 kJ/mol.

No. of moles of sulfur = 1 mole

$\Delta E_1 = 1000KJ/mol$

We know that plank's constant

$h = 6.626\times10^{-34} Js$

Let the frequency of photons be ν

Also we know that ΔE = hν

this implies ν = ΔE/h

$= \frac{10^6J}{6.626\times10^{-34} Js}$

$v = 1.509\times10^{39}Hz$

Hence, the frequency of photons $v = 1.509\times10^{39}Hz$
