    2. Chemical Change: Occurs when one or more substances are changed into new substances with different properties; cannot be undone by physical means

    3. Chemical Change is:

    4. Chemical Change is not:

    5. Chemical Change: Occurs when one or more substances are changed into new substances with different properties; cannot be undone by physical means

    6. Chemical Change is:

    7. Chemical Change: Occurs when one or more substances are changed into new substances with different properties; cannot be undone by physical means

    8. Chemical Change is:

    9. Chemical Reaction is: Change that take place when two or more substances (reactants) interact to form new substances (products)

    10. Chemical Reaction is:

    11. Chemical Reaction is not:

    12. Chemical Reaction is: Change that take place when two or more substances (reactants) interact to form new substances (products)

    13. Chemical Reaction is:

    14. Chemical Reaction is: Change that take place when two or more substances (reactants) interact to form new substances (products)

    15. Chemical Reaction is:

    16. Chemical Property is: The Characteristics of a substance that describe its tendency to combine with other substances and form new ones.

    17. Chemical Property is:

    18. Chemical Property is: The Characteristics of a substance that describe its tendency to combine with other substances and form new ones.

    19. Chemical Property is:

    20. Chemical Property is: The Characteristics of a substance that describe its tendency to combine with other substances and form new ones.

    21. Chemical Property is:

    22. Physical Property is: Property of matter that can be observed without changing the composition or identity of the matter

    23. Physical Property is:

    24. Physical Property is not:
