Answer:
P = 1.26 atm
Explanation:
Given that,
The number of moles, n = 1.42 mol
Volume, V = 28.1 L
Temperature, T = 305 K
We need to find the pressure of the gas. The ideal gas law is as follows :

R = 0.0821 L-atm/mol-K
Put all the values,

So, the pressure of the gas is 1.26 atm.
Answer:
HOMO of 1,3-butadiene and LUMO of ethylene
HOMO of ethylene LUMO of 1,3-butadiene
Explanation:
1,3 - butadiene underogoes cycloaddition reaction with ethylene to give cyclohexene.
According to Frontier molecular orbital theory HOMO of 1,3 butadiene and LUMO of ethylene and HOMO of ethylene and LUMO of ethylene underoges (4 + 2) in thermal or photochemical condition.
The answer is D-negative because protons are positive and neutrons are neutral
