experiment A student sees tiny bubbles clinging to the inside of an unopened plastic bottle full of carbonated soft drink. The student squeezes the bottle. Two 250 mL samples of water are drawn from a deep well bored into a large underground salt (NaCl) deposit. Sample #1 is from the top of the well, and is initially at 42 °C. Sample #2 is from a depth of 150 m, and is initially at 8 °C. Both samples are allowed to come to room temperature (20 °C) and 1 atm pressure. An NaCl precipitate is seen to form in Sample #1. predicted observation (choose one) O The bubbles will shrink, and some may vanish. O The bubbles will grow, and more may appear. O The bubbles won't change. O I need more information to predict what will happen to the bubbles. OA bigger mass of NaCl precipitate will form in Sample #2. OA smaller mass of NaCl precipitate will form in Sample #2. O The same mass of NaCl precipitate will form in Sample #2. O No precipitate will form in Sample #2.
