Question

intermolecular forces are *
a chemical bond made between substances due to sharing electrons
a force of attraction between substances due to distribution of electrons
determine if each of the following are chemical or physical changes *
8 points
chemical change
physical change
scrambling eggs in a bowl
a silver spoon tarnishing
a puddle drying up
chopping onions

Explanation:

Intermolecular forces are forces of attraction between substances due to the distribution of electrons. Chemical changes result in new substances, while physical changes do not. Scrambling eggs is a chemical change as proteins denature. Silver spoon tarnishing is a chemical change as silver reacts with sulfur - containing compounds. A puddle drying up is a physical change as water changes from liquid to gas without forming a new substance. Chopping onions is a physical change as it only changes the physical form of the onion.

Answer:

1. B. A force of attraction between substances due to distribution of electrons
2. Scrambling eggs in a bowl: Chemical Change
3. A silver spoon tarnishing: Chemical Change
4. A puddle drying up: Physical Change
5. Chopping onions: Physical Change
