Interpretation:
Number of second in 24 hours needs to be determined.
Concept introduction:
An arithmetical multiplier which is used to convert a quantity that is expressed in one set of units and equal to the other quantity in another unit is known as conversion factor.

Answer to Problem 22PP
There are 86, 400 seconds in 24 hour.
Explanation of Solution
A second is the short period of time. A minute is equal to 60 seconds. An hour is equal to 60 minutes. 1 day is equal to 24 hours.
The number of seconds in 24 hours is:
Thus, one day or 24 hours is equal to 86, 400 seconds.

Generate a molecular orbital diagram but this time using a different approach that draws on your knowledge and ability to put concepts together. First use VSEPR or some other method to make sure you know the ground state structure of the molecule. Next, generate an MO diagram for BH2. Sketch the highest occupied and lowest unoccupied MOs of the BH2 fragment. These are called frontier orbitals. Now use these frontier orbitals as your basis set for producing LGO's for B2H6. Since the BH2 frontier orbitals become the LGOS, you will have to think about what is in the middle of the molecule and treat its basis as well. Do you arrive at the same qualitative MO diagram as is discussed in the book?
