What is the formula for sulfate? What is the charge of sulfate?
What is the correct formula for copper (II) sulfate?

SO₄²-, -2, CuSO4

Explanation:

Dang that was long.

in the analysis of systems that involve fluid flow, we frequently encounter the combination of properties u and pv.

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.
