which answer below correctly identifies the type of change and the explanation when magnesium comes into contact with hydrochloric acid?\nphysical change because no color change occurred\nphysical change because the observation of a gas forming is evidence of a state change, which is reversible\nchemical change because a temperature change occurred, a solid disappeared, and a gas was produced\nchemical change because two substances were mixed, which always results in the formation of a new substance

Answer

Answer:

chemical change because a temperature change occurred, a solid disappeared, and a gas was produced

Brief Explanations:

When magnesium reacts with hydrochloric acid, a chemical reaction takes place. Signs of a chemical change include temperature change, disappearance of a solid reactant, and production of a gas. These indicate formation of new substances.
