Question

on the graph in problem 3, the letter corresponding the part of the curve where the solid and liquid phases coexist is _1_.what are the strongest intermolecular attractive forces between oxygen molecules?_2_a. a b. b c. c d. d e. e f. londons g. dipolar h. hydrogen bonds i. ion - dipole j. covalent bonds k. ionic bonds

Explanation:

• For the first question, in a heating curve, the flat - regions represent phase changes. The solid - liquid phase change (melting) occurs at the flat - region. In the given graph, the 'b' region is where the solid is melting to form liquid, so solid and liquid co - exist in this region.
• For the second question, oxygen (\(O_2\)) is a non - polar molecule. The strongest intermolecular forces between non - polar molecules are London dispersion forces.

Answer:

1. B
2. F
