When Bonds are made… • Energy is STORED when strong bonds are made. • Energy is RELEASED when weaker bonds are broken. **Be aware that this is a really simplified explanation that doesn’t do justice to the thermodynamics of chemical reactions.
Think about the possible meaning of following prefixes & suffixes with your table partner…(If you’re “all thought out” & have no idea, then go to your prefixes & suffixes sheet for help.)

Put the parts together. What does the word “Hydrolysis” mean?
Hydrolysis is… A chemical reaction in which a chemical compound is broken down with water.
Put the parts together. What does “Dehydration Synthesis” mean?
Dehydration Synthesis is… A chemical reaction in which 2 substances are joined and a water molecule is lost.
