Which change occurs when an atom in an excitedstate returns to the ground state?
(1) Energy is emitted.
(2) Energy is absorbed.
(3) The number of electrons decreases.
(4) The number of electrons increases.

Answers

Answer: The correct option is (1).

Explanation:

Whenever an atom in an excited state returns back to its ground state the energy is emitted out in the form of the radiation and the value of energy emitted can be determined by using the expression:

E=(hc)/(\lambda )

Where E = Energy of the radiation in joules

h = Planck's constant = 6.63* 10^(-34) J.s

\lambda= Wavelength of the radiation in meters.
The change that occurs when an atom in an excited state returns to the ground state is that (1) energy is emitted.
It is emitted by photons in the form of light, or in some cases, heat.

Which of the following mixture types can be filtered to remove solute? (1 point) suspensions only colloids only suspensions and colloids suspensions and solutions

Answers

The correct answer is suspensions only. The suspension is a heterogeneous mixture that contains solid particles that are largely enough to undergo sedimentation. Usually, these particles are about one micrometer which makes these solute to be very easy to be free from their solvent and be filtered.

The answer to your question is

suspensions only

example best shows that the chemistry of water is helpful to plants? Water’s polarity produces a high density, which allows water to move to the leaves. Water’s bent shape causes a slow passage of nutrients up to the leaves of plants. Water’s polarity causes cohesion that pulls other water molecules up through a plant. Water’s bent shape reduces its own passage through the cell membranes of roots.

Answers

The right answer for the question that is being asked and shown above is that: "Water’s polarity produces a high density, which allows water to move to the leaves." Example best shows that the chemistry of water is helpful to plants is that Water’s polarity produces a high density, which allows water to move to the leaves.

Answer:   Water’s polarity causes cohesion that pulls other water molecules up through a plant.

D. protons

AND NEUTRONS

The atoms in a compound are held together by a chemical bond. The chemical bonds can be either covalent bonds or ionic bonds. Both the bonds are considered very strong bonds. These bonds are mainly formed by sharing of electrons or in the case when one of the elements making the compound donates electron to the other element. The nucleus of each atom attracts to form a strong bond. This property of attraction between the nucleus of the atoms actually helps in forming the chemical bonds.
