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.

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?
