suppose that a substance in a beaker is heated over a burner in a science lab. which observation would most likely indicate that a chemical change has occurred in the substance?\no if the substance is a liquid or solid, an increase in temperature would indicate a chemical change.\no if the substance is a liquid, a change of some of the liquid to gaseous form would indicate a chemical change.\no if the substance is a solid, a change of some of the solid to liquid form would indicate a chemical change.\no if the substance is a liquid or solid, production of an odor would indicate a chemical change.
Answer
Brief Explanations:
A chemical change results in the formation of new substances. An increase in temperature, change of state (liquid - gas or solid - liquid) are physical changes. Production of an odor often indicates the formation of new substances, which is a sign of a chemical change.
Answer:
If the substance is a liquid or solid, production of an odor would indicate a chemical change.
