Question

identify each transition in this flowchart as a chemical change or a physical change.

Explanation:

A chemical change results in the formation of new substances with different chemical properties, while a physical change only alters the physical state or appearance without changing the chemical composition. In the flowchart, transitions labeled as 'chemical' show the formation of new molecular - level combinations, indicating a change in chemical identity. Transitions labeled as 'physical' show changes like separation or change in state without altering the chemical nature of the substances.

Answer:

The transitions labeled "chemical" are chemical changes as they involve the formation of new substances at the molecular level. The transitions labeled "physical" are physical changes as they only involve changes in the state or separation of substances without changing their chemical identity.
