Predict what will be observed in each experiment below. predicted observation (choose one) experiment O A bigger mass of NaCl precipitate will form in Sample #2. 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 A smaller mass of NaCl precipitate will form in Sample #2. The same mass of NaCl precipitate will form in Sample #2. initially at 42 °C. Both samples are allowed to come to No precipitate will form in Sample #2. room temperature (20. °C) and 1 atm pressure. An NaCl precipitate is seen to form in Sample #1. I need more information to predict whether and how much precipitate will form in Sample #2. The bubbles will shrink, and some may vanish. The bubbles will grow, and more may appear.
