To have 175ml is needed of a 9.0M H_{2} SO_{4} solution are needed to make 0.45 L of a 3.5 M (Morality).

<h3>How to calculate the molarity to make the solution?</h3>

The Morality unit (M) is $ \frac{\text { moles of solute }}{\text { liters of solution }}=\mathrm{mol} / \mathrm{L} $

The volume of a solution grows when it is diluted, while the solute concentration stays constant.

The following is the formula for dilution of a solution:

\mathrm{M}_1 \mathrm{~V}_1=\mathrm{M}_2 \mathrm{~V}_2

here \mathrm{M}_1 , \mathrm{M}_2 represents morality and \mathrm{~V}_1 , \mathrm{~V}_2 represents volume of solution in litres (L).

We are given the values: &\mathrm{M}_1=9.0 \mathrm{M}=9.0 \mathrm{~mol} / \mathrm{L} \\&\mathrm{M}_2=3.5 \mathrm{M}=3.5 \mathrm{~mol} / \mathrm{L} \\&\mathrm{V}_2=0.45 \mathrm{~L}

Now to calculate the volume of the solution i.e. \mathrm{V}_1=\frac{\mathrm{M}_2 \mathrm{~V}_2}{\mathrm{M}_1}

$\mathrm{V}_1=\frac{3.5 \mathrm{M} \times 0.45 \mathrm{~L}}{9.0 \mathrm{M}}=0.175 \mathrm{~L}$

In milliliters $\mathrm{V}_1=0.175\mathrm{~L} \times \frac{1000 \mathrm{mL}}{1 \mathrm{L}}=175 \mathrm{~mL}$

Answer the question briefly: How can atom collapse and why are atoms stable?
kykrilka [37]

The nuclei of atoms become unstable when the repelling forces of the protons cannot be balanced by the number of neutrons in the nucleus. It then re-arranges itself randomly to a more stable configuration by emitting any of a series of particles. During radioactive decay, an atom does not collapse.

Since an atom is mostly empty space - that is it’s nucleus is relatively distant from the electron shells so, in the presence of extreme forces such as gravity inthe collapse of a large star, the inward pressures on the atom overcome the natural balance of the atomic structure and the ‘empty space’ disappears as nuclei are mashed together by the intense pressures and a neutron star is formed. Under even more external pressure, even the neutron star can collapse to form a black hole.

These values also increase from the bottom to the top of a group because the size of the atom decreases, resulting in a distance
Allushta [10]

<span>These values also increase from the bottom to the top of a group because the size of the atom decreases, resulting in a smaller distance between the nucleus and the valence electron shell, which increases the attraction between the protons and electrons.</span>
