number of alka-seltzer tablets\t1\t2\t3\t4\t5
volume of vinegar (ml)\t100.0\t100.0\t100.0\t100.0\t100.0
room pressure (kpa)\t84\t84\t84\t84\t84
initial temp (°c) (vinegar solution)\t23.5\t23.5\t23.5\t23.5\t23.5
final temp (°c) (final mixture)\t22.6\t21.5\t20.4\t19.2\t18.1

1. which trial in the model 2 data table corresponds to the reaction illustrated in model 1?

Explanation:

To determine which trial in Model 2 corresponds to Model 1, we analyze the number of Alka - Seltzer tablets. In Model 1, the number of Alka - Seltzer tablets is 1. Looking at the Model 2 data table, Trial 1 has 1 Alka - Seltzer tablet, while Trials 2 - 5 have 2, 3, 4, and 5 tablets respectively. So we match the number of tablets.

Answer:

Trial 1
