A hot metal plate at 150°C has been placed in air at room temperature. Which event would most likely take place over the next few minutes? A. Molecules in both the metal and the surrounding air will start moving at lower speeds.

B. Molecules in both the metal and the surrounding air will start moving at higher speeds.

C. The air molecules that are surrounding the metal will slow down, and the molecules in the metal will speed up.

D. The air molecules that are surrounding the metal will speed up, and the molecules in the metal will slow down.

"record the time to complete a chemical reaction" would most likely be part of a lab procedure.

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.
