Will the mixture dissolve or not dissolve? How do you know?

• It will dissolve because molecules 2 and 3 have a high attraction to each other

• It will not dissolve because molecules 2 and 3 have a low attraction to eachother

• It will dissolve because molecule 2 has a low attraction to molecule 2

• It will not dissolve because both molecules are similar colors

Your friend says molecule 4 will connect with other molecule 4's. Is this true?

• True because it has a high attraction to other 4 molecules

• False because it has a low attraction to other 4 molecules

• True because they are both the same molecule

• False because they are not the same color
