Transcribed Image Text: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.
