canola oil
sodium chloride
sugar
water
the potassium ion
question 5 (2.5 points)
the bond in table salt (nacl) is ____.

Explanation:

Hydrophobic substances are non - polar and do not dissolve well in water. Canola oil is a non - polar lipid. Sodium chloride (\(NaCl\)) is an ionic compound (dissociates into ions in water, polar interaction). Sugar has hydroxyl (\(-OH\)) groups (polar, can hydrogen - bond with water). Water is a polar molecule. The potassium ion (\(K^{+}\)) is an ion (has a charge, can interact with polar water molecules).

Answer:

canola oil
