Answer:

There are mechanical energies. These consist of kinetic energy and gravitational potential energy.

Kinetic energy is the energy an object contains when it is in motion. Ex.: A car moving, a ball falling off of a building.

Gravitational potential energy is the potential for an object to do work at a certain height. If a 1 kg ball is placed 1 meter high, it has 9.8 Joules of potential energy, represented with the equation, Ug=mgh.

There are Non-Mechical Energies, which I assume you are trying to get. There is Thermal Energy, Electrical Energy, Light, Sound, Nuclear Energy, and Chemical Energy.

Thermal Energy is essentially heat. Friction causes thermal energy.

Electrical energy is potential difference. It is the work that can be done by a point charge.

Nuclear energy is like fission and fusion

Chemical energy is energy from chemical processses. Think, photosynthesis for example.

Sound is molecules hitting other molecules. It occurs a lot with friction as well.

Light is, well, you know what light is.

Which of the following molecules is diamagnetic according to molecular orbital theory? A) N₂⁺ B) N₂⁻ C) CN D) CN⁻

Gnom [1K]

Answer:

D) CN⁻

Explanation:

Hund's Rule of Maximum Multiplicity state that electrons go into degenerate orbitals of sub-levels (p,d, and f ) singly before pairing commences. Hund's rule is useful in determining the number of unpaired electrons in an atom. As such, it explains some magnetic properties of elements.

An element whose atoms or molecules contain unpaired electrons is paramagnetic. i.e., weakly attracted to substances in a magnetic field.

On the other hand, the element whose atoms or molecules are filled up with paired electrons is known as diamagnetic, i.e., not attracted by magnetic substances.

According to the molecular orbital theory, the diamagnetic molecule is CN⁻ because of the absence of unpaired electrons.

TRUE FALSE? The MOLE is a unit in Chemistry that serves as a bridge between the ATOMIC and MACROSCOPIC worlds?

Vanyuwa [196]

Answer:

True

Explanation:

A mole is defined as 6.02214076 × 1023 of some chemical unit, be it atoms, molecules, ions, or others. The mole is a convenient unit to use because of the great number of atoms, molecules, or others in any substance.
