The molecule CO2 have 2 lone pairs located in the oxygen atoms. It has two double bonds also connecting carbon atom to the two oxygen atoms. It does obey the octet rule so the atoms need 8 electrons in each of them that is why electrons are shared.
Answer: The standard entropy of vaporization of ethanol is 0.275 J/K
Explanation:

Using Gibbs Helmholtz equation:

For a phase change, the reaction remains in equilibrium, thus 

Given: Temperature = 285.0 K

Putting the values in the equation:


Thus the standard entropy of vaporization of ethanol is 0.275 J/K
4- Ag+ions thats the answer i hope its correct
