Uses of Distillation
Distillation is used for many commercial processes, such as the production of gasoline, distilled water, xylene, alcohol, paraffin, kerosene, and many other liquids. Gas may be liquefied and separate. For example: nitrogen, oxygen, and argon are distilled from air.
If you look at the periodic table you will see the atomic number (the smaller number) which is 3. that identifies how many protons there are. since the lithium is neutral that means there’s a same amount of electrons.
therefore there’s 3 electrons and 3 protons
Answer:

Explanation:
Hello,
In this case, since the molarity is computed by:

Whereas the solute is the hydrochloric acid, we compute the corresponding moles with its molar mass (36.45 g/mol):

Next, since the solution contains both HCl and water, we compute the volume in liters by using its density:

Therefore, the molarity turns out:
