Filtration, is a chemical process where you are separating a precipitate from a solution.
As a general rule:
"Solubility of compounds decrease with the increasing of temperature" as you can see in the graph
Now, if you want to recover benzoic acid from an aqueous solution, the better option would be with Ice cold water because its solubility will be lower producing more precipitate.

In acidic solution,<u> [H₃O ] > [OH⁻]. </u> The correct option is C.
<h3>What is hydronium and hydroxide ion?</h3>
Hydronium ion is the simplest form of oxonium ion, and it is derived from the protonation of water. It is produced by dissolving the Arrhenius acid in water.
Hydroxide ion is a diatomic anion formed with oxygen and hydrogen with single covalent bond.
The concentration of hydronium ions in an acidic aqueous solution will be higher than the concentration of hydroxide (OH-) ions.
Thus, the correct option is C, <u>[H₃O ] > [OH⁻].</u>

Answer:
The independent variable in on the x-axis, and the dependent variable is on the y-axis.
Explanation:
The independent variable belongs on the x-axis (horizontal line) of the graph and the dependent variable belongs on the y-axis (vertical line). The x and y axes cross at a point referred to as the origin, where the coordinates are (0,0).If you are confused, please check out this website talking more in-depth about graphing!

Answer:
The purpose or objective of the electromagnetic spectrum experiment the purpose is to figure out what elements are in the planets’ and the moons’ atmospheres by looking at their absorption spectrums
Explanation:
What is electromagnetic spectrum?
The electromagnetic spectrum is the range of frequencies (the spectrum) of electromagnetic radiation and their respective wavelengths and photon energies.
The electromagnetic spectrum covers electromagnetic waves with frequencies ranging from below one hertz to above 10^25 hertz, corresponding to wavelengths from thousands of kilometers down to a fraction of the size of an atomic nucleus. This frequency range is divided into separate bands, and the electromagnetic waves within each frequency band are called by different names; beginning at the low frequency (long wavelength) end of the spectrum these are: radio waves, microwaves, infrared, visible light, ultraviolet, X-rays, and gamma rays at the high frequency (short wavelength) end.
The electromagnetic waves in each of these bands have different characteristics, such as how they are produced, how they interact with matter, and their practical applications.
The limit for long wavelengths is the size of the universe itself.
