Additional solute is added to a saturated solution of a solid and a liquid after being heated above room temperature. Once no mo
PSYCHO15rus [73]

Answer:

After the solution is heated, but before additional solute is added

Explanation:

An unsaturated solution is a solution that contains less solute than it can normally hold at a given temperature. Hence an unsaturated solution can still dissolve more solute.

When the solution is heated, the saturated cold solution becomes an unsaturated hot solution which is capable of dissolving more solute at this point.

Once more solute is dissolved, the solution becomes saturated again just before it begins to cool since no more solute dissolves in the solution at some point before cooling and addition of seed crystals.

Water is a great solvent. For example, it causes ionic compounds like sodium chloride (table salt) to dissociate. One of these r
Ira Lisetskai [31]

Answer:

A polar molecule has both a partial positive and a partial negative. Since NaCl (sodium chloride) is made out of Na+ and Cl- ions, the positive and negative parts of the water will pull on these ions individually since positive attracts negative and negative attracts positive. This magnetic force causes the Na+ and the Cl- ions to be pulled apart.

to show the electron configuration for an atom, when would it be better to use an orbital notation than to use a written configu
sineoko [7]

The aim is to use less space while demonstrating the distribution of electrons in shells

If you want to depict how an atom's electrons are scattered across its subshells, an orbital notation is more suited.

This is due to the fact that some atoms have unique electronic configurations that are not readily apparent from textual configurations.

<h3>How does electron configuration work?</h3>

The placement of electrons in orbitals surrounding an atomic nucleus is known as electronic configuration, also known as electronic structure or electron configuration.

<h3>What sort of electron arrangement would that look like?</h3>
  • For instance: You can see that oxygen contains 8 electrons on the periodic table.
  • These 8 electrons would fill in the following order: 1s, 2s, and finally 2p, according to the aforementioned fill order. O 1s22s22p4 would be oxygen's electron configuration.
