Answer:
Ans: 5.8g
Explanation:
31.35L * 1mol/22.4L * 4.00g/1mol = 5.81g
The molecule expand to relieve steric strain before undergoing torsion to a non-planar structure in order to have several resonating structures.
<h3>What is a molecule?</h3>
It should be noted that a molecule simply mean the group of atoms that are bonded together that represents the smallest fundamental unit if the chemical compound.
It should be noted that structures containing fused benzene rings have extensive conjugation. Due to this, they can undergo resonance.
This is vital in decreasing the overall energy of the molecule and helps increase its stability. When there's a change in torsion angle to relieve the steric strain, the molecule won't be planar, hence, the energy will increase and the stability will reduce.

Answer:
The pressure is 16, 9 atm
Explanation:
We use the formula PV=nRT. The temperature in Kelvis is: 273 + 25 = 298K
PV=nRT P =(nRT)/V
P= (0, 450 mol x 0,082 l atm/K mol x 298)/0,650 l= 16, 91723077atm
The mass number is the sum of the protons and neutrons
64 = #protons + #neutrons
Find the number of protons given the number of neutrons
64 = #protons + 33
#protons = 31
In a neutral element (such as this), the number of electrons equals the number of protons
#electrons = #protons
#electrons = 31
First you want to convert the Celsius to Kelvin, so 10C will be 283.15K, and 100C will be 373.15K.
Then, we have to look at the PVnT relationships to determine what to do. Since T increases, that must mean V increases. And since pressure increases, V will increase from that too. I believe it can be assumed # of particles then stay constant.
1) The first ratio is your given value
20mL
———
1
2) you multiply the above by the ratio which favors the relationships: so if the given value is supposed to rise, then the bigger number should be on top, and vice versa. Since no info on # particles is included, that’ll be excluded.
.... 373.15K x 10atm
———— ————
283.15K 1 atm
So 1) multiplied by 2) gives 263.57 mL, which means the answer is none of the choices.
