A.
Part A Which statement best describes the change that occurs when copper metal is added to sulfuric acid?
Because a solid dissolved into a liquid, indicating a change of state, a chemical reaction occurred.
Because bubbles formed on the metal, indicating a change of state, the change is physical.
Because the volume of liquid decreases, indicating a temperature change, the change is physical.
Because the masses of the substances in the beaker is less after the metal dissolves, indicating that a gas and a new substance formed, a chemical reaction occurred.
Part A Arrange the following images and descriptions to show the phases of matter as water transitions from a solid to a gas from left to right.
