How is electron movement related to covalent bonding in
ammonia, NH3?
A) Electrostatic
sharing in a sea of electrons around the atoms allows bonds to form.
B) The atomic orbitals overlap and electrons are shared between the atoms
forming bonds.
C) A transfer of electrons forms ions which are electrostatically attracted
forming bonds.
D) Orbital exchange occurs between the atoms to redistribute the electrons and
form bonds.
The electron
movement related to covalent bonding in ammonia, NH3 is The atomic orbitals overlap and electrons are shared between the atoms
forming bonds. The answer is letter B.
When P1/P2 = C1/C2
and C is the molarity which = moles/volume
so, P1/P2 = [(mass1/mw)/volume] / [(mass2/mw)/volume]
P1/P2 = (mass1/mw)/1.5L / (mass2/mw)/1.5L
so, Mw and 1.5 L will cancel out:
∴P1/P2 = mass1 / mass2
∴ mass 2 = mass1*(P2 / P1)
= 0.278g * (78 bar / 62 bar)
= 0.35 g
∴ the quantity of argon that will dissolve at 78 bar = 0.35 g
Where are options? without that, i can’t help you sorry
C. MgCl2
This structure forms a ionic bond, which are generally stronger than covalent bonds. All of the other choices are covalent.
