Which is true about a liquid that has been converted to its solid state a) the kinetic energy of its molecules has increased b) the kinetic energy of its molecules has decreased c) the kinetic energy of its molecules is unchanged d) the molecules of the solid do not have any kinetic energy

i think it's c. if you look search electronic symbol on google and then click on wiki it shows you a

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.
