Background research about water purification and filtration!!!
notka56 [123]

Answer: It's a modern-day engineering challenge to remove human-made contaminants from

drinking water. After a quick review of the treatment processes that municipal water

goes through before it comes from the tap you will learn about the still-present

measurable contamination of drinking water due to anthropogenic (human-made)

chemicals. Substances such as prescription medication, pesticides and hormones are

detected in the drinking water supplies of American and European metropolitan cities.

The engineering design process can be used to design solutions for a real-world

problem (contaminated water) that could affect health.

Engineering Connection

The water that comes from our faucets has passed through a complex system designed

by many different types of engineers. Civil, chemical, electrical, environmental,

geotechnical, hydraulic, structural and architectural engineers all play roles in the

design, development and implementation of municipalities' drinking water supplies and

delivery systems. Hydraulic engineers design systems that safely filter the water at a

rate needed to supply a specific region and population. Chemical engineers precisely

determine the amounts and types of chemicals added to source water for coagulation

and decontamination to make the water safe to drink and not taste bad. Even so,

modern pharmaceutical and agricultural practices persist in contaminating our water

supplies.

You plan to separate a polar and a non-polar compound using normal phase column chromatography technique. Methylene chloride (CH
marissa [1.9K]

Answer:

Hexane should be used first.

Explanation:

Chromatography is a method of separating the constituents of a mixture by taking advantage of their different rates of movement in a solvent over an adsorbent medium. Chromatography is a means of separation and analysis that utilises fractional separation. It is based on the principle  that if a fluid containing a number of substances is allowed to pass though an adsorbent medium, the different substances in the fluid may travel at different rates and be separated.

The rate of movement depends on the relative affinities of the constituents for the solvent and adsorbent medium. i.e solutes which are weakly adsorbed by the adsorbent medium are easily redissolved by the ascending solvent and quickly travel up the adsorbent medium. In addition to that , solutes which are very soluble in the solvent move up at a faster rate than those which  are not soluble.

In column Chromatography;

A non-polar solvent should be initiated and applied first. This is because , in a column chromatography, a non-polar compound will be removed at first then later polar compound.

Assuming a polar compound is used first, the polar compounds will be removed alongside with all the non-polar compounds.

From the two Compounds given;

We know that :

Hexane is a non-polar compound and Methylene chloride  is a polar compound. As such, Hexane should be used first.

The number of oxygen atoms in 48.0g of oxygen gas
Doss [256]

Answer:

Now u have 48 g of O2. There. Fore mole=weight/M. W. Of oxygen. Therefor 3mole.

After that if we to multiply the avogadro number with it. So 3 *NA

Now u want only atom calculation then we have 2 molecule of oxygen then multiply it with 2 too.

So final claculation is =3*2*NA.

Explanation:

your welcome
