Which answer below correctly identifies the type of change and the explanation for the change in calcium carbonate?
physical change because even though a state change was observed, the calcium carbonate
retained its original properties
physical change because even though a particle size change was observed, the calcium
carbonate retained its original properties and was not transformed into a new substance
chemical change because a state change was observed, which indicated that the calcium
carbonate was transformed into a different substance
0 chemical change because a particle size change was observed, which indicated that the calcium
carbonate was transformed into a different substance

answer: i have one answer

acids are substances that ionize (break off) in an aqueous solution to produce hydrogen (h+) ions

explanation:

hope this and sorry i could only come up with one answer!

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.

it is reliable if two scientists recorded it
