One piece of matter is divided into two pieces of matter. Identify the mass of the two new pieces combined. A. It's the same as the original piece
B. It is greater than the original piece
C. It is less than the original piece
D. It cannot be measured
PLEASE HELP!! THANK YOU

A. It's the same as the original piece

Explanation:

The piece of matter is the same as that of the original piece.

When the mass of the two new pieces are combined, it the same as the single and whole one.

Mass is the amount of matter contained within a substance.

c is the answer because when something is left after something evaporates that shows the chemical 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.
