The process of separating alcohol from water can be done in several different ways. The most familiar method is through heating the blended liquid. Since alcohol has a lower boiling temperature than water, it will rapidly become steam. It can then be condensed into a separate container. You can also freeze the alcoholic mixture, which allows for partial removal of the nonalcoholic components; what remains will be more rich in alcohol. Use ordinary table salt to separate isopropyl alcohol from water. The result will be a condensed isopropyl alcohol, not a drinking alcohol.

Which set of compounds illustrates the law of multiple proportions? so2, so3 h2o, h2o2 n2o, no, no2 all of these?

Leto [7]

<span>All of these. All the gases that are mentioned in each set identify with the law of multiple proportions since the all the compounds have oxygen ions in them. Law of multiple proportions is defined as formation of compound with oxide ions after the reaction of an element with oxygen.</span>

Answer:

Molarity of HCl=0.026092M

Explanation:

The equation for the reaction is;

HCl + NaOH ⇒ NaCl + H2O

Using the formular, $\frac{C_{A}V_{A}}{C_{B}V_{B} }=\frac{nA}{nB}$ ..........equ1
