In the chemical formula 2so2, how many total atoms of sulfur (s) are there? 1 2 4

1 answer:

6 0

Sulfur has the coefficient of 2, and nothing else. This indicates Sulfur has 2 atoms.

<span>Oxygen on the other hand, has a subscript of 2, as well as the coefficient of 2. Multiplying those, and you see Oxygen has 4 atoms.
</span>
So your answer is 2

Also remember there is a 2 in front of S meaning there are 2 Sulfurs.
<span>If it was S02 it would be 1 Sulfur as there is no number in front of sulfer. </span>

<span>Remember the number in front of a element, represents how many atoms there are :)</span>

How does the structure of water explain its high boiling point, high heat capacity, and high heat of vaporization?

nikklg [1K]

Water's high heat capacity<span> is a property caused by hydrogen bonding among </span>water<span> molecules. When </span>heat<span> is absorbed, hydrogen bonds are broken and </span>water <span>molecules </span>can<span> move freely. When the temperature of </span>water decreases, the hydrogen bonds are formed and release a considerable amount of energy.
<span>Water's heat of vaporization is around 540 cal/g at </span>100 °C<span>, water's boiling point.

Identify the classification of milk a aerosol b solid emulsion c solid aerosol d foam e emulsion

enot [183]

option (c) emulsion is the right answer

Emulsion is a classification of milk.

<h3>Describe an emulsion.</h3>

In physical chemistry, an emulsion is a combination of two or more liquids in which one of the liquids is present as microscopic or ultramicroscopic droplets dispersed throughout the other.

<h3>How is emulsion used?</h3>

Emulsions form as a result of the cleansing action of soaps.

(ii) The emulsification process is how lipids are broken down in the intestines.

(iii) Disinfectants and antiseptics combine with water to generate emulsions.

(iv) The emulsification technique is utilized to create medications.

<h3>How is an emulsion created?</h3>

When two immiscible liquids, such as oil and water, are stirred together with an emulsifier—which might be a protein, phospholipid, or even a nanoparticle—emulsion is created.
