When bonded, the hydrogen atom
When bonded, the hydrogen atoms have their electron taken byOxygen atom, which gives them a partial positive charge of E. Theoxygen, therefore, has a net negative charge of -2e. The distancebetween oxygen and hydrogen is 0.9584 Angstrom. FIND the net forceon the oxygen atom. ( please explain them in details with giveninformation )
Answer:
The force extered on the oxygen atom by each hydrogen atom, fromCoulomb’s law, is given by :
F = ( 1 / 4
o) ( e x 2e ) / d2, in magnitude,
where, e = 1.6 x 10-19 C is the electroniccharge,
d = 0.9584 Angstrom = 9.584 x 10-11 m is the distancebetween two atoms,
and, ( 1 / 4o) = 9 x 109 S.I. is permittivity constant.
Hence, F = ( 9 x 109 ) x 2 x ( 1.6 x10-19 / 9.584 x 10-11 )2 N ~ 5 x10-8 N.
We know, there is an 105o angle between the H – O – Hbond in a water molecule.
Hence, net force on the oxygen atom is :
( F2 + F2 + 2F2 cos105o )
= 2 x F x ( 1 + cos 105o )
= 2 x 5 x 10-8 x ( 1 + cos 105o ) N
~ 6.087 x 10-8 N.
