Explanation:

atom changes from a ground state to an excited state by taking on energy from its surroundings in a process called absorption. The electron absorbs the energy and jumps to a higher energy level. In the reverse process, emission, the electron returns to the ground state by releasing the extra energy it absorbed

Where are four places a body fossils naught be created.

Oliga [24]

<span>Body fossils can mostly be found in things like rocks and minerals deep in the ground or in mountains and caves. They can also be found in quick drying substances such as for example tar pits or basically anywhere where there has been historically chance of encountering a fossil. You can also find them in peat, so that's 4 then.</span>

If molten sodium chloride is split by electrolysis, which reaction occurs at the anode?

mariarad [96]

Answer: $2Cl^-(l)\rightarrow 2e^-+Cl_2(g)$

Explanation:

Electrolysis of a subastance is breaking it into its constituents by the action of electrical current.

In the electrolysis of molten sodium chloride, sodium metal is produced at the cathode which is a negative electrode and chlorine gas produces as the anode which is a positive electrode.

$2NaCl(l)\rightarrow 2Na^++2Cl^-$

At anode : $2Cl^-(l)\rightarrow 2e^-+Cl_2(g)$

At cathode : $2Na^+(l)+2e^-\rightarrow 2Na(l)$

Why is an atom electrically neutral?

Orlov [11]

Electrons have electric charge of -1 and the number of electrons in an atom is equal to the number of protons. ... Heavier atoms tend to have more neutrons than protons, but the number of electrons in an atom is always equal to the number of protons. So an atom as a whole is electrically neutral.

Hey!<br> I need a simple connotation of how glowsticks glow.<br> Please and thank you.

LenaWriter [7]

Answer:

simple

Explanation:

The glow stick's outer plastic tube holds a solution of an oxalate ester and an electron-rich dye along with a glass vial filled with a hydrogen peroxide solution. ... Glow sticks light up when oxalate esters react with hydrogen peroxide to form a high-energy intermediate

It is the balance between thermal energy and intermolecular forces that determines the state of matter of any substance at room

ExtremeBDS [4]

Answer:

The correct option is;

2) Thermal energy increases by a factor of R

Explanation:

The equipartition energy theorem states that when molecules are in a state of thermal equilibrium, particles within the system posses equal average energy with each degree of freedom which can be known as energy due to a state of having a particular temperature or thermal energy given by the relation

$E_{th}$ = Kinetic energy of translation + Kinetic energy of rotation + Energy of vibration

For a mono-atomic gas, $E_{th}$ = 3/2·n·R·T

For a diatomic gas, $E_{th}$ = 5/2·n·R·T

For a solid element, $E_{th}$ = 3·n·R·T

Therefore, as the temperature is doubled, the thermal energy increases by a factor of R.
