Answer: 2. Bonds and bond energies of the molecule
Explanation:
The absorption spectrum is an electromagnetic spectrum which is used for observing the intensity of the radiations which have been absorbed by the substances shown by the pattern of dark lines or bands. Infrared and microwave spectroscopy are specialized techniques which are used for observing the bonds and bond energy of the molecules which can be observed by measuring the frequencies at which the radiations are absorbed.
12.2 C
It has 3 significant figures now.
109.5
tetrahedral shape:
number of electron pair = 4,
number of bonded pair = 4,
number of lone pair = 0.
I think 3 of them are its been 1 half years since ive done this i dont take chemistry anymore
