Answer:
4
Explanation:
Avogadro’s number represent the number of the constituent particles which are present in one mole of the substance. It is named after scientist Amedeo Avogadro and is denoted by .
Also, it is the number of particles in exactly 12.000 g of isotope carbon 12.
Avogadro constant:-
Hence,
Mass of = 131.293+ n18.998 g
So,
molecules have a mass of 131.293+ n18.998 g
Also,
molecules have a mass of g
So,
molecules have a mass of g
Also, given mass = 0.172 g
Thus,
<u>Thus, value of n is 4.</u>
The U-235 fission will produce krypton-92 and barium-141. And this process will also release huge amount energy. And U-235 also go through α decay model.
Answer:
1. false - they are usually poor conductors and are not very malleable or ductile.
2. false (most of the mass is in the nucleus...electrons are extremely light)
Explanation:
<span>The answer is - a. Alkali Metal.
</span>They react violently with water to form alkaline solutions. This is because they all have 1 electron in their outer shell and losing 1 electron allows them to have full outer shells, and achieve stability.

Fission is the energetic splitting of large atoms such as Uranium or Plutonium into two smaller atoms, called fission products. To split an atom, you have to hit it with a neutron.
Hope this helped.
