What is pure water??? In detailed explanation

2 answers:

8 0

Pure water, also known as purified water, is water from a source that has removed all impurities. Distilled water is the most common form of pure water. Pure water can be purified by carbon filtration, micro-porous filtration and ultraviolet oxidation. Some places use a combination of purification processes.

Answer:

Purified water is water that has been filtered or processed to remove impurities like chemicals and other contaminants.

Explanation:

Distilled water is a type of purified water that is essentially free from contaminants. The distillation process removes fluoride and natural minerals found in drinking water.

Drinking water, which we usually think of as pure, really contains a whole mess of salts and sugars which make it slightly hypertonic. They also give water its taste.

Explain the bonding that occurs between sodium and chlorine. Specifically, what kind of bonding takes

babymother [125]

Answer:

Ionic bonds form when atoms transfer electrons between each other, forming ions that are electrically attracted to each other forming a bond between them. Sodium chloride (NaCl) is a typical ionic compound. The picture below shows both a sodium and a chlorine ion.

Explanation:

ionic bond

Because of the propensity of sodium to lose an electron and of chlorine to gain an electron, the elements are well suited to bond with one another. This transfer of electrons results in the formation of the ionic bond holding Na+ and Cl– together.

Give the name of this alcohol.

solong [7]

Answer:

An alcohol is an organic compound with a hydroxyl (OH) functional group on an aliphatic carbon atom. Because OH is the functional group of all alcohols, we often represent alcohols by the general formula ROH, where R is an alkyl group. Alcohols are common in nature.

The heat of vaporization of a liquid is 84.0 J/g. How many joules of heat would it take to completely vaporize 172 g of this liq

Aliun [14]

Answer:

14,448 J of heat would it take to completely vaporize 172 g of this liquid at its boiling point.

Explanation:

The heat Q that is necessary to provide for a mass m of a certain substance to change phase is equal to Q = m*L, where L is called the latent heat of the substance and depends on the type of phase change.

During the evaporation process, a substance goes from a liquid to a gaseous state and needs to absorb a certain amount of heat from its immediate surroundings, which results in its cooling. The heat absorbed is called the heat of vaporization.

So, it is called "heat of vaporization", the energy required to change 1 gram of substance from a liquid state to a gaseous state at the boiling point.

In this case, being:

Q=?
m= 172 g

L= 84 $\frac{J}{g}$

and replacing in the expression Q = m*L you get:

Q=172 g*84 $\frac{J}{g}$

Q=14,448 J

<u><em>14,448 J of heat would it take to completely vaporize 172 g of this liquid at its boiling point.</em></u>

What does non polar mean?

Hoochie [10]

When atoms bond together to form molecules, they share or give electrons. If the electrons are shared equally by the atoms, then there is no resulting charge and the molecule is nonpolar.
