3) Answer is: because elements have different emmision spectrum.
Emission spectrum of a chemical element is the spectrum of frequencies emitted due to an atom making a transition from a high energy state to a lower energy state. Each element's emission spectrum is unique.
4) Answer is: lithium chloride and sodium chloride do not have similar colors.
Lithium ion has red and sodium ion has yellow emission spectrum.
5) Answer is: because metals have valence electrons in different energy shells.
Each transition has a specific energy difference.
6) Answer is: salts of alkaline and earth alkaline metals.
For example barium chloride gives green light.

Answer:</h3>
A saturated solution is a chemical solution containing the maximum concentration of a solute dissolved in the solvent.
<h3>
Explanation:</h3>
- A solution is made by dissolving a solute in a solvent.
- For example dissolving a salt in a solvent such as water results to a solution.
- Solution may either be saturated or unsaturated.
- Unsaturated solution is a solution that can dissolve more solute upon addition because it has not reached saturation.
- A saturated solution on the other hand is a solution that has maximum solute and the concentration of solute is maximum and thus the solvent can not dissolve any more solute.
- Therefore, a saturated solutions contain maximum concentration of a solute dissolved in the solute.
Answer:
As potassium chloride (KCl) dissolves in water, the ions are hydrated. ... Ion-dipole forces attract the positive (hydrogen) end of the polar water molecules to the negative chloride ions at the surface of the solid, and they attract the negative (oxygen) ends to the positive potassium ions.
