Correct option is B ethyl ethanoate
The following compound is ester R−COO−R ′ and the naming of ester are done on the basis of alkanoate group (R−COO−) and alkyl (R ′ ) combined to form ester.The suffix for ester is "-oate". The full name of ester is like alkyl alkanoate. Thus the name of given compound is ethyl ethanoate.

Answer:
P = 5.14ATM
Explanation:
Number of moles = 0.108moles
Temperature (T) = 20°C = 20 + 273.15 = 293.15K
Volume V = 0.505L.
Pressure (P) = ?
R = 0.082J/mol.K
From ideal gas equation,
PV = nRT
P = nRT / V
P = (0.108 * 0.082 * 293.15) / 0.505
P = 2.596 / 0.505
P = 5.14ATM
The pressure of the gas is 5.14ATM
Answer:1) It is due to large cohesive force acting between the molecules of mercury that the droplets of mercury when brought in contact pulled together to form a bigger drop in order to make potential energy minimum. The temperature of this bigger drop increases since the total surface area decreases.
2) A spherical shape has the minimum surface area to volume ratio of all geometric forms. When two drops of a liquid are brought in contact, the cohesive forces between their molecules coalesce the drops into a single larger drop. This is because, the volume of the liquid remaining the same, the surface area of the resulting single drop is less than the combined surface area of the smaller drops. The resulting decrease in surface energy is released into the environment as heat.
