Answer: Water
Explanation:
Chemically speaking, a solution has two components: solute and solvent.
The <u>solute</u> is that substance (usually solid, but it can also be liquid or gas) that dissolves in a liquid substance and <u>its proportion in the resulting solution is usually less than the solvent.
</u>
The <u>solvent</u> is the substance used to <u>dissolve the solute, and generally its proportion in the resulting solution is greater.</u> Being the most common used solvent water.
This means that in a solution there is usually more solvent than solute.
So, in the case of the hydrogen peroxide solution, since the proportion is
to
, the hydrogen peroxide is the solute and water is the solvent.
Answer:
has 17 electrons
Explanation:
Chlorine is a halogen that belongs to the 17th group on the periodic table. Chlorine has an atomic number of 17. The atomic number of elements is used in placing and locating elements on the periodic table. In fact, the periodic arrangements of elements is as a result of their atomic numbers.
The atomic number is the number of protons in an atom. This number is the same as the number of electrons in a neutral atom that has not gained or lost any electron.
It is correct to say chlorine has 17 electrons and they occupy 3 electronic shells.
Answer:
Unchanged.
Explanation:
Hello,
In this case, for the experiment you performed, as you previously removed the sodium chloride, its % salt calculation will not be affected by the lost of the sand. It is important to remember that such experiments must be performed carefully as the committed error is a high-impact factor regarding to the experiment's performance. It is important for you to remember that to separate the sodium chloride, it earlier dissolution in water allowed to be dissolved leveraging the insolubility of sand in water, thus, it was decanted easily.
Best regards.
