a)
The water molecule consists of two hydrogen atoms and one oxygen
atom. Since the oxygen atom has a higher electronegativity than the
hydrogen atom, the side of the molecule with the oxygen atom has a
partial negative charge.
Assume that the partial positive charge on each hydrogen atom is
Q2 = 0.512 x 10-19 C. What is the
electric charge Q1 on the Oxygen atom?
b)
The water molecule forms an angle, with hydrogen atoms at the
tips and the oxygen atom at the vertex (see diagram in the previous
problem).
Assume that the angle at the oxygen atom is θ (theta) =
104.0o and the distance between the oxygen and the
hydrogen atoms is d = 95.3 x 10-9 m.
Calculate the magnitude of the net electrostatic force on the
oxygen atom. Use the charges from the previous problem.

Predict which intermolecular forces contribute the most to the dissolution of NaCl in water?
NaCl is an ionic solid. The Na+ and Cl− ions in NaCl are bonded through an electrostatic force of attraction commonly known as the ionic bond. Water is a polar solvent. The oxygen atom, being more electronegative, attracts the electron cloud toward itself. As the electron cloud is pulled by the oxygen atom, it carries a partial negative charge, and the hydrogen atoms carry a partial positive charge. This partial separation of charges in the water molecule makes it polar....

In a covalent bond between two atoms, the more electronegative atom will attract more electron density toward itself, producing a polar bond. The more electronegative element will carry a partial negative charge, whereas the less electronegative element will carry a partial positive charge. The direction of the bond dipole is always toward the more electronegative element. This is often indicated by an arrow, as shown in the figure. The magnitude of the bond polarity can be estimated by using the...
A covalent bond is a bond in which electrons are shared between atoms of elements
A covalent bond is a
bond in which electrons are shared between atoms of elements. A
covalent bond can be polar or nonpolar. In a nonpolar covalent
bond, the bond is between two identical atoms and the electrons are
evenly shared between the atoms.In contrast, in a
polar covalent bond, the bond is between two nonidentical atoms and
the electrons are unevenly shared between the atoms. The uneven
sharing of electrons takes place because of the difference in the
electronegativity...
