3 0

According to the research, the correct option is a bar graph. It is the best way to show the lead levels in six contaminated water wells.

<h3>What is a bar graph?</h3>

It is a graph that is used to show the changes that the data have undergone by graphing the data in bars, representing the frequencies by means of columns (or bars), through their height in a Cartesian plane.

It is a way of summarizing a set of data by categories, allowing different values to be compared using bars of different sizes.

Therefore, we can conclude that according to the research, the correct option is a bar graph. It is the best way to show the lead levels in six contaminated water wells.

I had 10 molecules of Ag and an unlimited supply of H2S. How many molecules of Ag2S could I produce?
rjkz [21]

Answer:

5.12 molecules of Ag₂S could be produced from 10 molecules of silver.

Explanation:

Given data:

Molecules of Ag = 10 molecules

Molecules of Ag₂S = ?

Solution:

First of all we will convert the number of molecules into gram.

10/ 6.022 ×10²³ = 1.7 × 10⁻²³ mol

Mass of Ag:

Number of moles = mass/ molar mass

Mass = Number of moles × molar mass

Mass = 1.7 × 10⁻²³ mol × 107.9 g/mol

Mass = 183.43 × 10⁻²³ g

Chemical equation:

2Ag  + H₂S  →  Ag₂S + H₂

Now we will compare the moles of silver with Ag₂S from balanced chemical equation.

         Ag           :         Ag₂S

          2             :          1

     1.7 × 10⁻²³    :          1/2 ×1.7 × 10⁻²³  = 0.85 × 10⁻²³ mol

Molecules of Ag₂S:

0.85 × 10⁻²³ × 6.022 ×10²³ = 5.12 molecules

Answer;

Solvent

Explanation;

-A solution is a homogeneous mixture that is made of two or more substances.  In other words, It is a mixture in which one of the substances dissolves in the other. The substance which dissolves is called the solute while the substance that dissolves the solute is called the solvent.

-In a solution of a carbonated beverage, water acts as the solvent which dissolves the components added as solute to make the beverage. These components include sugars and other types of salts such as sodium citrate, all dissolved in water.

What type of van der Waals interactions occur between molecules
BigorU [14]

Given what we know, we can confirm that the type of van der Waals interactions that occur between molecules of O2, SCl2, and CH4 in liquids of these substances are the presence of <u>London dispersion forces</u>.

<h3>What are London dispersion forces?</h3>
  • They are a force of attraction between atoms.
  • They are generated by electrostatic attraction.
  • These forces are common between atoms in close proximity and occur often when compounds have a symmetrical distribution of atoms.
  • They are generated by the formation of temporary dipoles.

Therefore, given the symmetry of the atoms disposition in these compounds and the temporary dipoles generated by the atoms being in close proximity, we can confirm that the van der Waals forces present in each compound are London dispersion forces.
