Explanation:

Nearly all the mass of an atom is concentrated in the nucleus. ... A particle with mass m1 exerts a force F12 on a particle with mass m2. ... Earth and Moon attract each other via the gravitational force. ... The electric charge of the proton is positive, the charge of the electron is ... Lecture 1: What holds our world together?

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.

c) should be the answer.
