Question

match each attractive force with the name or description
column a

1. c intramolecular force
2. b bond
3. f intermolecular force
4. broken during a chemical change
5. broken during a physical change
6. requires the most energy to break
7. running electricity through water will break this
8. distilling a sample of soda will break this

column b
a. c
b. b and c
c. a and c
d. a
e. a and b
f. b

Explanation:

1. Intramolecular forces are forces within a molecule, which are A and C in the diagram.
2. Bonds are intramolecular forces, so B and C.
3. Intermolecular forces are between - molecules, which is B.
4. Chemical changes break intramolecular forces (bonds), so A and C.
5. Physical changes break intermolecular forces, so B.
6. Intramolecular forces (bonds) require the most energy to break, so A and C.
7. Running electricity through water (electrolysis) breaks intramolecular bonds, so A and C.
8. Distilling a sample of soda (a physical change) breaks intermolecular forces, so B.

Answer:

1. c
2. f
3. c
4. c
5. f
