Chemical Potential Energy Review Sheet

I. Types of Bonds

A. What are the two kinds of strong bonds? Explain the difference between

them.

B. What are the two kinds of weak bonds? Explain the difference between

them.

C. Which kind of bond is a hydrogen bond?

D. How does electronegativity play a role in the type of bond that forms

between atoms?

E. Draw what a typical ionic substance looks like at the atomic level.

F. Draw what a typical molecule looks like at the atomic level (for

example, water)

G. A drop of water contains many water molecules. Draw a small sample

of water molecules and indicate where there are strong bonds and

where there are weak bonds in this group of molecules.

H. Why are some substances hard and some soft?

I. Why do some substance have a high boiling point and some have a low

boiling point?

II. Formulas and Equations (see back for examples)

A. Know how to write formulas and names for substances. (Like the

“Naming Various Substances Sheet”)

B. Know how to balance equations.

C. Know how to take a paragraph description of a chemical reaction and

write a balanced chemical equation to described what happened using

chemical formulas.

D. Be able to add states of matter to chemical equations and use the

solubility rules.

III. Chemical potential energy

A. Which type of bond has more chemical potential energy - a strong bond

or a weak bond?

B. Will a chemical reaction that is spontaneous have a low or a high

activation energy?

C. Why are catalysts important for life? How do they work?

D. Draw an energy diagram showing an exothermic and an endothermic

reaction.
