(Assume that the volume does not change upon the addition of barium hydroxide.) A. The number of moles of HF will remain the same. B. The number of moles of F- will remain the same. C. The equilibrium concentration of H3O will decrease. D. The pH will increase. E. The ratio of [HF] / [F-] will increase. Submit AnswerRetry Entire Group

i'm pretty sure it is letter c.) car

geosphere and hydrosphere.

this is because the geosphere has to do with geological events, while the hydrosphere controls all water on earth.

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.

it is b that is the answer.
