Answer:

Dipole-dipole attractions

Explanation:

The Cl atom is more electronegative than H, so it attracts the electrons in the H-Cl bond more to itself.

The Cl end of the molecule becomes partially negative (δ-), and the H end becomes more positive (δ+). This separation of charge is called an electric dipole,

When two HCl molecules are near each other, they arrange themselves so that the negative and positive ends of the dipoles line up and attract the two molecules together.

Consider these ground-state ionization energies of oneelectron species:

SVETLANKA909090 [29]

Answer:

Explanation:

general expression for the ionization energy of any one-electron species.

= z² x ground level energy / n²

z is atomic no , n is energy level .

ground level energy of

H = 1.31 x 10³ kJ/mol

He⁺ = 2² x 1.31 x 10³ kJ/mol = 5.24 x 10³ kJ/mol

Li²⁺ = 3² x 1.31 x 10³ kJ/mol = 1.18 x 10⁴ kJ/mol

b ) the ionization energy of B⁴⁺.

= 5² x 1.31 x 10³ kJ/mol = 32.75 x 10³ kJ/mol

c ) minimum energy required to remove the electron from the n = 3 level of He⁺ per mole

= 5.24 x 10³ / 9 kJ/mol

= 5.82 x 10² kJ/mol

= 5.82 x 10² x 10³ / 6.02 x 10²³ J

.9667 X 10⁻¹⁸ J

= .9667 X 10⁻¹⁸ / 1.6 X 10⁻¹⁹ eV

= 6.042 eV

= 1237.5 / 6.042

= 204.82 nm

If a black ball is denser than a white ball of the same size, what does the black ball have??

yKpoI14uk [10]

Answer: The black ball will have more mass than the white ball.

Explanation: Density of a substance is defined as the ratio of mass and volume occupied by the substance.

Mathematically,

$Density=\frac{Mass}{Volume}$

We are given that the two balls are of same size, which means that the volume of both the balls are same. We are also given that the black ball is more dense than the white ball, which means that the black ball will have more mass.

As, $Density\propto Mass$

Which type of galaxy forms when two other galaxies crash into each other? They are small galaxies made up of bright, young stars

GenaCL600 [577]

Answer:

elliptical galaxy

Explanation

:The combination of the two galaxies then forms what appears to be an elliptical galaxy as the arms begin to disappear. The merger of gasses creates new stars, and the new shape becomes more elliptical, globular, or sometimes irregular.
