Predict what will be observed in each experiment below. experiment 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) A bigger mass of NaCl precipitate will form in Sample #2. A smaller mass of NaCl precipitate will form in Sample #2. The same mass of NaCl precipitate will form in Sample #2. No precipitate will form in Sample #2. O I need more information to predict whether and how much precipitate will form in Sample #2. A student has two unopened 33 cL cans containing carbonated water. Can A has been stored in the garage (32 °C) and can B has been stored in the fridge (8 °C). The student opens one can at the time, both cans make a fizz. O Can A will make a louder and stronger fizz than can B. O Can B will make a louder and stronger fizz than can A. The fizz will be the same for both cans. There is not enough information to predict which can will make the louder fizz. X
