The benzene molecule has the molecular formula C6H6
.
Sometimes it is represented as a molecule with three doble bonds and three single bonds. But that does not count for the fact that experimentally all the bonds are equal: same length and same strength.
The six carbon bonds are equal because there is not preference for the valence electrons to attach to one or othe neighbor carbon, so at the electrons delocalize inside the molecules and form a uniform cloud around the six carbon atoms.
This is the effect named resonance and thas is why the molecule of benzene instead of being represented with some three single bonds and three doble bonds is represented with a circle (a ring) inside the molecule which represents an intermediate kind of bond shares by all the carbon atoms.
This structure was discovered (literally dreames as some texts tell) by Kekulé.
For both of them, used the balanced equation and it’s mole ratio to convert whatever you need to into moles. See the attacked work.
1) D 5 mols
2) A 0.55 mols
Here is the link to the answer:
Decomposition is a chemical reaction that breaks the reactant into two or more products. Moles of nitrogen gas 
in the cylinder is 1.63 moles.
<h3>What is the ideal gas equation?</h3>
The ideal gas equation states the relation of the hypothetical ideal gas according to the pressure, volume, temperature and moles of the gas. It is given by,
Where,
Pressure (P) = 2000 kPa
Volume (V) = 2L
Temperature (T) = 295 K
Gas constant (R)= 0.08206
Substituting values in the equation:
Therefore, 1.63 moles are produced.
