Answer:
The pressure of the gas is 0.278 atm
Explanation:
Step 1: Data given
Number of moles of the ideal gas = 0.540 moles
Volume = 35.5 L
Temperature = 223 K
Step 2: Calculate the pressure of the gas
p*V = n*R*T
⇒with p = the pressure of the gas = TO BE DETERMINED
⇒with V= the volume of the gas = 35.5 L
⇒with n = the moles of the gas = 0.540 moles
⇒with R = the gas constant = 0.08206 L*atm/mol*K
⇒with T = the temperature of the gas = 223 K
p = n*R*T / V
p = 0.540 * 0.08206 * 223 / 35.5
p = 0.278 atm
The pressure of the gas is 0.278 atm
Answer:
The order will be:
CCH > CHCH₂ > CH₂CH₃> CH₃
Explanation:
According to Cahn-Ingold-Prelog system we rank the groups based on the atomic number of directly attached atom with the chiral carbon.
For example: between C and H, we rank Carbon first.
If the same atoms are attached for different groups then we prioritized based on the second element with highest atomic number.
For example:
Among CH₃ and C₂H₅, the priority will be given to C₂H₅.
If an atom is double or triple bonded to the directly attached atom then each pi bond is considered to be a new atom.
Hence CH=CH₂ means, that there are two carbons attached to CH carbon.
So the order based on above selection rules will be:
CCH > CHCH₂ > CH₂CH₃> CH₃
