How does the reaction outlined here demonstrate the conservation of mass? The energy stored in the bonds was conserved both before and after the reaction.

The number of atoms before they rearranged is equal to the number of atoms after they rearranged.

The number of molecules both before and after the reaction is constant.

Energy was utilized to transform the arrangement of some atoms to a different arrangement.

Mrs. smith ordered a root beer float (vanilla ice cream + root beer). mrs. smith noticed that the three states of matter (solid, liquid, and gas) all existed simultaneously in her root beer float. a. identify each phase of matter in the root beer float. b. describe the particles of all three phases of matter in the root beer float. (how are the particles arranged and moving? ) c. identify one phase change you would see in a root beer float and described what causes this change.
