Consider the molecule BF3. (a) What is the electron config- uration of an isolated B atom? (b) What is the electron con- figurat
anzhelika [568]

For the given molecule, we are asked to give-

  1. The electron configuration of an isolated B atom
  2. The electron configuration of an isolated F atom
  3. Hybrid orbitals should be constructed on the B atom to make the B–F bonds in Boron tri flouride
  4. valence orbitals, if any, remain unhybridized on the B atom.
  • The electron configuration of an isolated B atom:

as atomic number of B is 5

electronic configuration will be [He] 2s² 2p¹

  • The electron configuration of an isolated F atom:

as atomic number of F is 9

electronic configuration will be  [He] 2s² 2p5

  • Hybrid orbitals should be constructed on the B atom to make the B–F bonds in Boron tri flouride will be sp2.

as the one s and two of p orbital from the valance shell will hybridised to make 3 hybrid orbital of B resulting in 3 B-F bonds.

  • valence orbitals, if any, remain unhybridized on the B atom will be 1

What is the molarity of a solution if you take 12.0 grams of ca(no3)2 and mix it with 0.105 l of water?
Lunna [17]
The  molarity  of  a solution  if it tale 12.0   grams  of  Ca(No3)2  is  calculated as below

molarity =  moles/volume in liters
 moles = mass/molar mass =  12.0 g/ 164 g/mol =  0.073 moles

molarity is therefore  = 0.073/0.105 = 0.7 M
