Predict what will be observed in each experiment below. Rock candy is formed when excess sugar is dissolved in hot water followed by crystallization. A student wants to make two batches of rock candy. He finds an unopened box of "cane sugar" in the pantry. He starts preparing batch A by dissolving sugar in 500 mL of hot water (70 degree C). He keeps adding sugar until no more sugar dissolves in the hot water. He cools the solution to room temperature. He prepares batch B by dissolving sugar in 500 mL of water at room temperature until no more sugar is dissolved. He lets the solution sit at room temperature.
1. It is likely that more rock candy will be formed in batch A. It is likely that less rock candy will be formed in batch A.
2. It is likely that no rock candy will be formed in either batch.
3. I need more information to predict which batch is more likely to form rock candy.
A student has two unopened 33 cL cans containing carbonated water. Can A has been stored in the garage (32 degree C) and can B has been stored in the fridge (8 degree C). The student opens one can at the time, both cans make a fizz.
1. Can A will make a louder and stronger fizz than can B.
2. Can B will make a louder and stronger fizz than can A.
3. The fizz will be the same for both cans.
4. There is not enough information to predict which can will make the louder fizz.
