The two basic steps to determine whether a molecule is polar are:
</span>
<span><span>1) determine whether the molecule contains polar bonds?
</span>
2) determine whether the polar bonds add together to
form a net dipole moment.
Explanation:
The fundamental requirement is that there are polar bonds. Polar bonds are covalent bods with dipole moments. Dipole moments are the result of two atoms of different electronegativity sharing electrons. The more electroneative atom pulls the electrons with more strength than the other atom which is what generate the dipole moment.
If the molecule is symmetrical, and the dipole moments are place symmetrically they wil cancel each other and the molecule will not be polar. For example, the molecule of CCl4 has four C - Cl bonds each with dipole moment, but they are loacates symmetrically around the C atom, so they will cancel each other resulting in a zero net sum of dipole moments, being the molecule non-polar.

Answer:
0.914moles
Explanation:
The number of moles in a substance can be got by dividing the number of atoms/molecules/particles by Avagadro's constant (6.02 × 10^23).
That is;
number of moles (n) = number of atom (nA) ÷ 6.02 × 10^23
According to this question, there are 5.5 x 10-23 molecules of H2O
n = 5.5 x 10^23 ÷ 6.02 × 10^23
n = 0.914 × 10^(23-23)
n = 0.914 × 10^0
n = 0.914 × 1
n = 0.914moles
Answer:
A
Explanation:
Flammability is a chemical property. The paper crumbling would be a physical property. The inability to attract a magnet or conduct electricity would be considered electrical properties
