Which of the following changes has a decrease in entropy? (3 points)

1.) 2LiClO3 (s) —> 3O2 (g) + 2LiCl (s)

2.) N2O4 (g) —> 2NO2 (g)

3.) C6H6 (l) —> C6H6 (s)

4.) C2H5OH (l) + 3O2 (g) —> 2CO2 (g) + 3 H2O (g)

It is no 3 a solid has the least entropy and here it changes from liquid to solid unlike 1,2,and4

im not exactly sure but i think its b!

the correct answer is b. a strong acid completely dissociates to its ions when dissolved in water. completely dissociates to and ions. a is incorrect because does not fully ionize to and ions and some remain as the compound . c and d are incorrect because, and do not fall into the category of bronsted lowry acids. a bronsted lowry acid is a proton donor and since both molecules do not have a proton to donate they are not bronsted lowry acids. likewise,   if we use the lewis acid definition, they cannot be acids. a lewis acid is an electron pair acceptor. both and have a complete octet so can not accept any electrons which disqualifies them as acids.
