how are liquids described in terms of shape and volume?

A liquid is a incompressible fluid that molds to the shape of its container but retains a constant volume independent of pressure. It is one of the four fundamental states of matter and is the only state with a definite volume but no fixed shape.

Basically: Liquids is anything that has a definite volume but not a definite shape.

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.
