DOUBLE JEOPARDY! Explain the differences between a physical and chemical property. Give examples of each
If the matter present is changed (new molecules produced from reactions) by testing the property, it is a chemical change.
If matter stays the same then only a physical change occurred and physical properties are observed.
Give an example of a chemical change(or a reaction) and 2 pieces of evidence that a reaction occurred.
What is rusting? Color change, formation of precipitate, etc...
What is AgNO3 & copper? Color change, precipitate forms, heat released, etc...
