I'll give brainliest <br>why the total energy of electron is negative
kramer

Answer:

Electrons are always marked negative Hence electronic energy is also always taken as negative. It is because when an electron is at infinite distance from nucleus , there the kinetic energy of that electron can not be calculated. So, it is taken to be zero . ... And thus the energy of electron becomes less negative

For each described change, determine the generally expected impact on a salt's solubility. LABEL No solubility change, SOLUBILIT
Anna [14]

Answer:

A- Solubility decrease.

B- Solubility increase.

C- No solubility change.

Explanation:

Hello!

In this case, since the solubility of salt stands for the maximum amount of salt that can be added to a specific mass of water, usually 100 g; we need to take into account that for table salt in aqueous solution, the higher the temperature the larger the solubility and the lower the temperature the smaller the solubility; it means that more salt is dissolved in the same mass of water at higher temperatures and vice versa. Therefore, A- would decrease the solubility as the solution is cooled down and B- would increase the solubility as the solution is heated up.

Moreover, since the mass of water is assumed to remain the same, adding more salt do not affect the solubility but increase the degree of saturation of the solution up to supersaturated, yet the solubility remains unchanged.

Best regards!

Where do we find the most abundant natural supply of Cl- ions
Mashcka [7]

Answer:

Chlorine is found abundantly in earth crust and ocean.

Explanation:

The elements of group 17 are called halogens. These are six elements Fluorine, Chlorine, Bromine, Iodine, Astatine. Chlorine is one of them.

it is greenish-yellow irritating gas.

its melting point is 172.2 K

its boiling point is 238.6 K

It is present in earth crust and ocean abundantly.

In ocean chlorine is found in the form of salt sodium chloride.

About 1.9% mass of sea water consist of chlorine ions.

In earth crust it is present in minerals such as carnallite and sylvite.

it is disinfectant and can kill the bacteria.

it is also used in manufacturing of paper, paints and textile industries.

It is also reported that chlorine can effect the respiratory system, immune system and heart.

Up to some extent it can also effect the organism living in water.
