kicyunya [14]1 year ago

The vapour of a pure chemical substance depends on the level of a intermolecular forces, that substance's structure, and the temperature.

<h3>What are instances of intermolecular forces?</h3>

Between molecules, intermolecular forces are at work. In contrast, molecules themselves exert intramolecular pressures. In comparison to intramolecular forces, intermolecular forces are weaker. The Weaker intermolecular forces, dipole-dipole interaction, ion-dipole communication, and van der Waals forces are a few examples of intermolecular forces.

<h3>What causes intermolecular forces?</h3>

Electrostatic in nature, forces between molecules result from the interaction of positive and negative charges entities. Forces between molecules are the total of both attracting and repulsive elements, similar to held together by covalent connections.

Why can't the reaction, ZnCl2 + H2 → Zn + 2HCI, occur naturally?
Llana [10]

Answer:

It is fairly obvious that zinc metal reacts with aqueous hydrochloric acid! The bubbles are hydrogen gas. ... In fact, electrons are being transferred from the zinc atoms to the hydrogen atoms (which ultimately make a molecule of diatomic hydrogen), changing the charges on both elements.

Which change most likely occurs when the kinetic energy of water vapor decreases during condensation?
mylen [45]

Answer:

When the kinetic energy of water vapor decreases during condensation, <u>slowly moving particles near the cool surface condense.</u>

Explanation:

The change of state from a gas to a liquid is condensation. Liquid molecules which have this certain kinetic energy threshold escape from the surface and become vapor. As a result, the remaining liquid molecules now have lower kinetic energy. The temperature of the remaining liquid decreases as evaporation occurs.

The air that surrounded it cooled the cold can or glass. When you're cooling off  .They lose kinetic energy, a gas. The particles move more slowly as they move, the  attractions between them cause the formation of droplets of liquid. Condensed With,  when hot air containing water vapor reaches water, water also forms.  Cold surface touch, such as a glass of ice or soil that has a cold surface  refrigerated throughout the night.

The principal quantum number (n): specifies the maximum number of electrons. specifies the 3-D shape of the orbital. none of the
kodGreya [7K]

The principal quantum number (n): specifies the principal shell of the orbital.

The answer is option D.

The important quantum number (n) describes the dimensions of the orbital. Orbitals for which n = 2 are larger than those for which n = 1, as an example. Because they have got opposite electric costs, electrons are interested in the nucleus of the atom.

The numerals, called essential quantum numbers, imply strength degrees as well as the relative distance from the nucleus. A 1s electron occupies the energy stage nearest the nucleus.

A 2s electron, less strongly certain, spends most of its time farther far from the nucleus.
