Question
A person mixes two liquids together as shown in the illustration below. The person can conclude that there was a chemical change because: some of the mixture changed into a different state of matter; part of the mixture formed a new material with different properties; the total mass stayed the same after mixing the substance; the temperature didn’t change after the liquid were mixed)

The person can conclude that there was a chemical change primarily because "part of the mixture formed a new material with different properties." This indicates that a chemical reaction occurred, resulting in the formation of substances with new characteristics.
While changes in state and temperature can indicate physical or chemical changes, the key indicator of a chemical change is the formation of new substances with different properties. The total mass being the same is consistent with the law of conservation of mass, which applies to both physical and chemical changes, so it does not serve as evidence of a chemical change by itself.
