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.

To identify which liquid is water you need to be able to test different ways with the different substances and see which liquid acts more like water. Sense of smell, water has a specific scent smell the substances and you’ll get closer to figuring out which is water
Answer:
Iron (II) oxide
Explanation:
Chemical formula of the given compound = FeO
The given compound is an oxide.
In oxides, oxidation state of 'O' is -2.
Let oxidation state of Fe be x. It is a neutral compound.
Therefore, x - 2 = 0
x = +2
So, the oxidation state of Fe in FeO = +2
In the nomenclature of inorganic compounds, cation is named first. After that oxidation state of cation is written. Name of anion is written after that.
Cation = Iron
Anion = oxide
So the name of the given compound would be Iron (II) oxide.
Answer:
The answer to your question is [NObr] = 1.41
Explanation:
Data
Kc = 2
[NO] = 2 M
Br₂ = 1.0 M
NOBr = ?
Process
1.- Write the Equation of the Kc
Kc =
2.- Solve for [NOBr]
[NOBr]² =
3.- Substitution
[NOBr]² =
4.- Simplification
[¨NOBr]² =
[NOBr]² = 2
5.- Result
[NOBr] =
[NOBr] = 1.41
