Answer:
Infrared radiation lies between the visible and microwave portions of the electromagnetic spectrum. Infrared waves have wavelengths longer than visible and shorter than microwaves, and have frequencies which are lower than visible and higher than microwaves

Helloooooooooooooooooooooo
Saturated solution refer to a solution in which the dissolved solute is in equilibrium with the undissolved solute.
<h3>What is a saturated solution?</h3>
A saturated solution is a chemical solution that contain maximum amount of a solute which is dissolved in the solvent. The addition of anotheg solute will not dissolve in a saturated solution. The amount of solute that can be dissolved in a solvent to form a saturated solution depends on a variety of factors.
Therefore, Saturated solution refer to a solution in which the dissolved solute is in equilibrium with the undissolved solute

Fe(NO3)2=0
Fe+2(+3+3*-2)=0
Fe+2*-3=0
Fe=-(-6)
Fe=+6
So, Fe=+6, N=+3, O=-2
Answer:
The number of neutrons is obtain through the difference of the mass number and the number of electrons
Explanation:
By looking at the periodic table, you will see that Fluorine has 9 protons.
Since the number of electrons equal the number of protons, Fluorine has 9 electrons as well.
Meanwhile, it's mass number of 19, minus 10 neutrons, gives you 9 protons or electrons. Hence, the atom would be Fluorine.
As for the atomic number, it is obtainable through the periodic table itself.
