determine the strongest intermolecular force in pure samples of each of the following: a. h2o b. cf4 c. co2 d. ph3
Virty [35]

The strongest intermolecular force is the hydrogen bond in water (H2O).

What is intermolecular force?
Intermolecular forces
are those that develop between the molecules of a substance and can cause them to attract or repel one another. The type of intermolecular force that is present in the matter determines all of the material's physical and chemical properties.

Interactions between dipoles
Involvements of Ion-Dipoles
Dipole Interactions Induced by Ions
DID Interaction: Dipole Induced DID
London Forces or Dispersion Forces
These five intermolecular force types are listed above.


The intermolecular forces were in this order:
The strongest force is ion-dipole force.
the hydrogen bond
Force between dipoles
the least powerful is the dispersion force.
The strongest intermolecular force is therefore the hydrogen bond in H2O.

What are the differences between amorphous and crystalline solids? Give an example of each.
Eddi Din [679]

Answer: orderly arrangement of particles

Explanation:

In a crystaline solid, the particles that compose the solid are arranged or packed in an orderly manner to form a three dimensional crystal lattice with a defined structure. Sodium chloride is a crystaline solid.

In an amorphous solid, the particles that compose the solid aren't arranged in an orderly manner hence the solid tends to be brittle, e.g glass

Calcium cyanamide, CaCN2, reacts with water to form calcium carbonate and ammonia. CaCN2(s)+3H2O(l)→CaCO3(s)+2NH3(g). How many g
Norma-Jean [14]

298 g of calcium carbonate CaCO₃

Explanation:

We have the following chemical reaction:

CaCN₂ (s) + 3 H₂O (l) → CaCO₃ (s)+ 2 NH₃ (g)

number of moles = mass / molar weight

number of moles of H₂O = 161 / 18 = 8.94 moles

Knowing the chemical reaction we devise the following reasoning:

if        3 moles of H₂O produces 1 mole of CaCO₃

then  8.94 moles of H₂O produces X moles of CaCO₃

X = (8.94 × 1) / 3 = 2.98 moles of CaCO₃

mass =  number of moles × molar weight

mass of CaCO₃ = 2.98 × 100 = 298 g
