When marble chips are placed into an acidic solution, the mass of the marble decreases as it reacts with the acid and is stripped away. large marble chips have been recorded to lose 2 grams of mass over 7 minutes. which of the following best describes how small chips would react to the same acid? a. the small chips would react more slowly and would have a lower net loss. they would lose 1 gram over the 7 minutes, and would not lose more mass if left for a longer time. b. the small chips would react faster, losing 2 grams over 3.5 minutes and then staying constant, not losing any more mass, for the remainder of the time. c. the small chips would react faster, losing 4 grams over the same 7 minutes. d. the small chips have less mass and would react more slowly, losing 2 grams over 14 minutes.
