edict what will be observed in each experiment below. experiment A pair of 100 mL samples of water are taken from a well bored into a large underground salt (NaCl) deposit. Sample #1 is from the top of the well, and is initially at 32 °C. Sample #2 is from a depth of 50. m, and is initially at 42 °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. A student sees tiny bubbles clinging to the inside of an unopened plastic bottle full of carbonated soft drink. The student squeezes the bottle. predicted observation (choose one) O A 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. O I need more information to predict whether and how much precipitate will form in Sample #2. The bubbles will shrink, and some may vanish. O The bubbles will grow, and more may appear. The bubbles won't change. O I need more information to predict what will happen to the bubbles.
