This lab question is: How can you distinguish a physical change from a chemical change? Which statements below are an appropriate hypothesis in response to this question? Check all that apply.
If a substance changes state of matter (e. g., liquid to gas), then this is a physical change because the
original properties of the substance have not changed.
If a substance undergoes a physical change, then it will retain most of its original properties because
no new substance is formed.
If a substance undergoes a chemical change, then it will not retain its original properties because a
new substance is formed.
If a precipitate is formed when two substances are mixed, then a chemical change has taken place
because precipitates are new substances.
