Background research about water purification and filtration!!!

Chemistry
1 answer:
notka56 [123]3 years ago
5 0

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.

Answer:

Hydrogen and Oxygen

Pureified water has been filtered or processed to remove impurities like chemicals and other contaminants, while tap water is not and it is composed of minerals that may not be seen in purified water.

Chemicals are the most common type of water contaminants. They affect both surface and underground water bodies. Industries and farming activities are the leading cause.

The reaction of nitrogen gas and oxygen gas to form nitrogen monoxide gas is shown below. If the measured concentrations of all
Anettt [7]

Answer:

The forward reaction is occurring at a faster rate than the reverse reaction.

Explanation:

Reaction quotient (Q) of the given reaction is -

                                     Q=\frac{[NO]^{2}}{[N_{2}][O_{2}]}

where [NO], [N_{2}] and [O_{2}] represents concentrations of respective species at a certain time.

Here [N_{2}]= 0.80 M, [O_{2}]= 0.050 M and [NO] = 0.10 M

So, Q=\frac{(0.10)^{2}}{(0.80)\times (0.050)}=2

Hence Q> K

It means that forward reaction is faster than reverse reaction at that point. Because then only concentration of NO is higher than concentrations of [N_{2}] and [O_{2}] which makes Q higher than K.

if the following is one strand of DNA what would be the corresponding strand of mRNA that is sequenced from it
Dmitrij [34]

Answer:

U A G C C A U C G G A U C C G A U

Explanation:

In DNA, A=T, C=G, and vice versa. RNA has U instead of T. So dna to rna: adenine = uracil, thymine = adenine, cytosine = guanine, and guanine = cytosine.

How does fire impact the various populations of trees?
Anuta_ua [19.1K]

It plays a key role in shaping ecosystems by serving as an agent of renewal and change. But fire can be deadly, destroying homes, wildlife habitat and timber, and polluting the air with emissions harmful to human health. Fire also releases carbon dioxide a key greenhouse gas into the atmosphere

Two moles of lithium has a mass of 13.88g. true or false
Dafna1 [17]
From the periodic table:
the mass of lithium = <span>6.941 grams
Since lithium is monoatomic, therefore, the molar mass of lithium = </span><span>6.941 grams

Now, we need to calculate the mass of two moles of lithium:
mass of two moles of lithium = 2 * </span><span>6.941 = 13.882 grams

Based on the above calculations, the answer is:
True</span>
