Write an 250 words about Water Purification and Filtration

Chemistry

Answer:

Water purification is the process of removing undesirable chemicals, biological contaminants, suspended solids and gases from contaminated water. The goal is to produce water fit for a specific purpose. Most water is purified for human consumption (drinking water), but water purification may also be designed for a variety of other purposes, including meeting the requirements of medical, pharmacological, chemical and industrial applications. In general the methods used include physical processes such as filtration,sedimentation, and distillation, biological processes such as slow sand filters or biologically active carbon, chemical processes such asflocculation and chlorination and the use of electromagnetic radiation such as ultraviolet light.

Extreme lack or loss of water may lead to dehydration of the body and other health complications. For this reason, governments ensure that citizens have access to clean and safe water for domestic use. Clean water is essential in ensuring that no pathogens or impurities are ingested by people, either through direct drinking or through food.

To attain these standards of water, purification is important. Water purification involves physical and chemical processes, which are carried out stepwise to ensure the water is safe and free from any harm. This directional process essay synthesizes the steps, which have to be followed to achieve this task.

In essence, water purification denotes the process used to free water from impurities like bacteria and contaminants. Since the process is aimed at eliminating all the impurities present in the water, it is necessary to apply chemical and physical methods of separation in an orderly manner.

Richard Arkwright is known as father of modern factory system​ why?
Arturiano [62]

Answer:

He started factories and mills. He created World's first water- powered mill at Cromford, where he employed more than 200 people. This was just the beginning of the many factories which he would later set up. Because of this, Arkwright was known as the father of the modern industrial factory system........Hope you got it

The question is incorrect, the correct question is;

Which of the following ground-state electron configurations represents the atom that has the

lowest first-ionization energy?

a) 1s2

b) 1s22s2

c) 1s22s22p6

d) 1s22s22p63s23p1

e) 1s22s22p63s23p3

The correct ground state configuration that represents the atom that has the lowest first ionization energy is 1s² 2s² 2p⁶ 3s² 3p¹.

The first ionization energy is the energy required to remove an electron from the outermost shell of an atom.

Ionization energy decreases down the group as number of shells increases but increases across the period as nuclear charge increase.

As the number of shells increases, the degree of shielding or screening decreases it easier to remove the outermost electron.

The elements whose ground state electronic configurations were shown are;

Helium - 1s²  

Beryllium - 1s² 2s²  

Neon - 1s² 2s² sp⁶  

Aluminum - 1s² 2s² 2p⁶ 3s² 3p¹    

Phosphorus - 1s² 2s² 2p⁶ 3s² 3p³

Aluminium (1s² 2s² 2p⁶ 3s² 3p¹) is a metal so it has the lowest first ionization energy since metals are highly electropositive.

A 40 g gold coin is cooled from 50°C to 10°C (CAu is 0.13 J/g-°
Debora [2.8K]
When the Heat gain or lose = the mass * specific heat * ΔT

and when we have the mass of gold coin= 40 g 

and the specific Heat of gold=  0.13 J/g°

and ΔT = (Tf- Ti) = 10°C - 50°C = -40 °C

so by substitution:

∴Heat H = 40 g * 0.13 J/g° * -40
               = - 208 J
