The lewis structure looks something like this:
O=C-O ....| ...O
with the hydrogen atoms bonded to two of the Oxygen atoms. There are two other resonance structures which means that a double bond does not actual exist in the molecule. Instead there's a pair of delocalized electrons that span the entire molecule. This means that all three bonds are actually equal and thus the molecule has a trigonal planar geometry. You can also tell that it's trigonal planar because the central atom is sp2 hybridized.
Answer:
The molar mass of N5O9
is 214.0245g/mol
Explanation:
To solve this problem, we need to know each number of mole of each element present in the compound
N has 5 moles
O has 9 moles
Then, we multiple each number of mole by its number of mass of each element present
N - 14.0067
O - 15.999
Multiplying by mole
N - 5 * 14.0067 = 70.0335
O - 9 * 15.999 = 143.991
Therefore,
Molar mass of N5O9 = 70.0335 + 143.991
= 214.0245g/mol

Answer: True
Explanation:
The speed of light in a material medium depends on its molecular structure, in particular its electromagnetic properties, electrical and magnetic permeability. These properties may have different values for different wavelengths or frequencies of the incident light.
In this way,<u> the speed of light depends on the medium and reaches its maximum value in a vacuum</u>, so that, it will be lower in a material medium . In the vacuum (or in the air) the speed of light is 3 x 10⁸ m / s and in any other medium its value is lower.
<u>To characterize the particularities of the propagation of light in the media</u>, the refractive index is introduced
,
n = c / v
where c is <u>speed of light in a vacuum</u> and v is t<u>he speed of light in the medium</u> considered
. So the speed of light in a medium is given by the refractive index whose value is always greater than 1.
