Answer is: ammonia experience only dispersion intermolecular forces with BF₃ (boron trifluoride) because BF₃ is only nonpolar molecule (vectors of dipole moments cansel each other, dipole moment is zero).
The London dispersion force (intermolecular force) <span>is a temporary attractive </span>force between molecules.
Answer:metres
Explanation:It would be best to measure the length of an object in metric system such as millimeter, centimeter, mere etc..
The first one is D, the second one is A and the last is C and D
The density is 3.144 g / cm^3.
<u>Explanation</u>:
If effective number of atom in NaCl type structure, z = 4
a = 705.2 pm ⇒ In centimeter = 705.2
10^-10
Na = 6.023
10^23
density = (molecular weight) (z) / (Na) (a^3)
where molecular weight of KI is 166 g,
Z represents the atomic number
density = (molecular weight) (z) / (Na) (a^3)
= (166
4) / (6.023
10^23)
(705.2
10^-10)
density = 3.144 g / cm^3.
Answer:
