Intermolecular forces are the interactions between molecules and are generally weaker than bonds within molecules. Which molecul
telo118 [61]

Answer:

Molecules that will have dipole-dipole forces with like molecules include the water (H2O) molecule. Another example is the Hydrogen Chloride (HCl) molecule.

Explanation:

Intermolecular forces are forces of attraction or repulsion that exist between particles (ions, atoms, or molecules) that are close/in nearby proximity to each other. Usually, intermolecular forces are not as strong as intramolecular forces which create covalent or ionic bonds between the atoms that exist within molecules. Dipole-dipole interactions occur whenever the partial charges that exist within one molecule are attracted to the opposite partial charges that exist within another different molecule that is nearby and similar in composition: the positive end/charges of one molecule are attracted to the negative end/charges of another similar molecule.

An example of molecules that exhibit dipole-dipole interaction is the water (H2O) molecule. Another molecule which exhibits dipole–dipole interaction is the Hydrogen Chloride (HCl) molecule, whereby the positive end of one HCl molecule usually attracts the negative end of another HCl molecule.

Two (2) moles of an ideal gas are in a container at 200 kpa and a temperature of 300 k. The volume occupied by the gas in the co
k0ka [10]

The volume occupied by the gas in the container is 1 m³

Boyles law applies

P₁ V₁ = P₂ V₂

Where P₁ = 200kpa

P₂ = 300kpa

if its initial volume is 1.5

then,

P₁ V₁ = P₂ V₂

200 × 1.5 = 300 × V₂

V₂ = 200 × 1.5 / 300

    = 1 m³

Hence  the volume occupied by the gas container is 1 m³

How many moles are there in 3.612 x 1024 formula units of Na2SO4?
vitfil [10]

Answer:

<h3>Theanswer is 6 moles</h3>

Explanation:

To find the number of moles in a substance given it's number of entities we use the formula

n =  \frac{N}{L}  \\

where n is the number of moles

N is the number of entities

L is the Avogadro's constant which is

6.02 × 10²³ entities

From the question we have

n =  \frac{3.612 \times  {10}^{24} }{6.02 \times  {10}^{23} }  \\

We have the final answer as

<h3>6 moles</h3>

Hope this helps you
