Question
Predict wnat will be observed in each experiment below predicted observation (choose one) experiment 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 °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 ino 500 mL of water at room temperature until no more sugar is dissolved. He lets the solution sit at room temperature. O It is likely that more rock candy will be formed in batch A. O It is likely that less rock candy will be formed in batch A. O It is likely that no rock candy will be formed in either batch. I need more information to predict which batch is more likely to form rock candy O Can A will make a louder and stronger fizz than can B. 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). TheThe fi O Can B will make a louder and stronger fizz than can A. student opens one can at the time, both cans make a fizz. There is not enough information to predict which can will make the louder fizz.Explanation / Answer
1. The correct statement is the first one.
Explanation: At 70 oC (i.e. batch A), more sugar will be dissolved in water, hence the precipitation of rock candy will be more during recrystallization. While at room temperature (i.e. batch B), comparatively less sugar will be dissolved in water, hence the precipitation of rock candy will be less during recrystallization. Hence, more rock candy will be formed in batch A.
2. The correct statement is the second one.
Explanation: Can A was stored at 32 oC, where the disorder is more and fizz will be created automatically with less effort. Whereas Can B was stored at 8 oC, which has the more ordered arrangement and fizz will be generated inside and not allowed to come out. Hence, Can B make a louder and stronger fizz than Can A.
