Three students are asked to discuss the percent error obtained from this lab and explain some sources of error that would account for the discrepancy seen, if any. Select the student that employs correct scientific reasoning. . Student 1: If the reaction was not allowed to go to completion, the sodium bicarbonate would not have fully decomposed, making the final mass higher than the theoretical. Student 2: If the baking soda was not heated long enoughthe final mass of solid product would be low. Student 3: The student didn't weigh the masses correctly therefore human error is the main source of discrepancy. . Student 3 Student 1 O Student 2
