1) hydrogen and oxygen make up water, you need 2hydrogens to every oxygen hence H2O.

2) water is polar because the oxygen atom is much more electronegative than the hydrogens pulling the bonded e closer. hence has polar bonds and is an asymmetrical shape so don't cancel each other out and is an over all polar molecule.

Virty [35]

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.
