Question 6 (5 points) All of these reactions that show a change are known as "double-displacement"
reactions. Write a summary about how aqueous (liquid) ionic compounds react, using
the term double-displacement reaction, and discussing how many reactions showed
a change and how many did not. Be sure to explain how you know a chemical
reaction has occurred.
