Go to the reagent bench and get a mortar and pestle. Place a small lump of sulfur in the mortar. Return to your bench and grind the sulfur to a powder. Pour the ground sulfur powder into the trash can. Wipe the sulfur off the mortar and pestle well with a paper towel and return them to the reagent bench. Observations:
Is this a chemical or a physical change?

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.
