<h3><u>Answer;</u></h3>

= 4.81 × 10^22 particles

<h3><u>Explanation</u>;</h3>

The molar mass of Cr2(SO3)3 is 344.18 g

1 mole of a substance contains 6.02 10^23 particles

But; 1 mole of chromium (iii) sulfite = 344.18 g

Therefore;

344.18 g = 6.02×10^23 particles

27.5 g = ?

Hence;

= (27.5 × 6.02 × 10^23)/344.18

<h3><u>= 4.81 × 10^22 particles </u></h3>

<span>The Avogadro constant, named after the scientist Amedeo Avogadro, is the number of constituent particles, usually atoms or molecules, that are contained in the amount of substance given by one mole. The answer, in this case, would be 0.0004999...*10^23 = (10^19)*(4.999... [any finite number of 9s]).</span>

why don't electrons, which are attracted to the protons in the nucleus, simply fall into the nucleus?
Murljashka [212]

Answer:

electrons are fermions, they can only access an energy level if it has not already been occupied by another electron. Thanks to this principle, there is a minimum energy level within the atom and it is not possible for an electron to collapse to the nucleus because it cannot exceed this} threshold.

Explanation:

I hope I have helped you.
