Consider that the room is a closed system. ryan uses the chemical energy in his muscles to create the energy of motion. he uses this energy of motion to pull the string on the clapper of a bell to produce a sound. sound fills the room.

which describes the energy in this room?

a.
as energy changes forms, total energy decreases.

b.
as energy changes forms, total energy increases.

c.
while energy is changing forms, total energy at first increases, then decreases.

d.
while energy has taken different forms, total energy remains the same.

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.

answer: i dont know the answer but this might
