For each molecule, specify the polarity of the bonds and the overall polarity of the molecule. A. A central beryllium atom is connected to two chlorine atoms through single bonds.
B. Each chlorine atom has three lone pairs of electrons.
C. A central oxygen atom is connected to two hydrogen atoms through single bonds.
D. There are two lone pairs of electrons around the oxygen atom.
Are the bonds for each one polar or non polar? Are the molecules for each one polar or non polar?
A. BeCl2
B. H2O
C. O3

See explanation

Explanation:

We know that the possession of polar bonds does not make a molecule polar. The BeCl2 molecule has Be-Cl bonds which are polar. However, the molecule is symmetrical and has a zero net dipole moment hence the molecule is nonpolar.

H2O is a polar molecule. It has polar O-H bonds. The molecule is bent and has a resultant dipole moment hence it is polar.

Ozone is a triatomic molecule which is bent in shape. This bent geometry creates an overall dipole moment in the molecule, hence the molecule is polar.

i believe it is 40–40–20%

explanation:

the number of protons in the nucleus of a given element. has slight luster and conducts electricity at high temperatures like metal.but like a nonmetal,boron is brittle and does not conduct electricity well at low temperatures. in graphite, carbon is a soft,brittle solid.it is reflective,ductile,or malleable.
