-g Which three of the statements are true? The tendency of water to minimize its contact with nonpolar substances is called the hydrophobic effect. Hydrophobic molecules do not readily dissolve in water in part because water molecules involved in hydration cannot participate in normal hydrogen bonding with one another. Hydrophobic molecules are individually hydrated in water, increasing the entropy of the system. Nonpolar molecules are capable of forming micelles. Amphipathic (amphiphilic) lipids are the structural basis of biological bilayer membranes.

21. consider the following chemical reaction: n2+ o2 2 no if 10.0 g of n2 reacts with excess oxygen then how many grams of no can be formed? a) 10.7 g b) 21.4 g c) 32.9 g d) 42.8 g page 4 of 8

Sulfur dioxide and oxygen react to form sulfur trioxide during one of the key steps in sulfuric acid synthesis. an industrial chemist studying this reaction fills a 25.0l tank with 4.5 mol of sulfur dioxide gas and 4.5 mol of oxygen gas at 30.°c. he then raises the temperature, and when the mixture has come to equilibrium measures the amount of sulfur trioxide gas to be 1.4 mol. calculate the concentration equilibrium constant for the reaction of sulfur dioxide and oxygen at the final temperature of the mixture. round your answer to 2 significant digits.
