suppose that a bf3 molecule approaches the lone pair on the N atom of an ammonia molecule (:NH3) and that a bond forms between the B atom and the N atom. Consider the arrangement of electron pairs about the B atom at the moment of this bond formation and describe the repulsions among the electron pairs and how they might be expected to change the geometry around the boron atom. Use Lewis structures to illustrate your explanation.

A hydrogen atom must be directly bonded to F, N, or O in a molecule in order to participate in a hydrogen bonding. Select one: True False Question 2 As the strength of temporary (induced) dipoles decreases within a substance, the boiling point increases. Select one: True False Question 3 The lines in a phase diagram of a given substance represent the co-existence curves where two phases of the same substance are present at equilibrium for a well-defined set of...

What is the center of mass of the ammonia molecule? This molecule has the chemical formula...

What is the center of mass of the ammonia molecule? This molecule has the chemical formula NH3. It is comprised of one nitrogen atom and three hydrogen atoms. The hydrogens are positioned at the corners of an equilateral triangle (with side length 0.16 nm) which forms the base of a pyramid. The nitrogen atom is at the apex of this pyramid, a vertical distance of 0.037 nm above the plane of the equilateral triangle. The lengths and distances in this...

Suppose a photon is absorbed by the electron in a hydrogen atom in an n= 2 state. What wavelength should the photon have to enable the electron to transition to the n= 4 state? Once the photon is absorbed, what are the various wavelengths of photons that could be emitted by the atom? (Use Bohr approximation).

Consider a molecule of hydrogen chloride, HCl. In this molecule, the light hydrogen atom orbits the heavy Cl atom, much like an electron orbits a heavy nucleus in an atom. The energy of H in the molecule is quantized. When exposed to electromagnetic field, the molecule HCl absorbs photons that promote the hydrogen atom to higher energy states, corresponding to faster rotation of H about Cl. What do you think is the approximate frequency of these photons? a) The frequency...
