19. Suppose the students had mixed a 12.5 g sample of Margarine B and a 12,5 a samplerde Margarine C. Further suppose that they had tested this mixed sample following the procedure
from Experiment 1. Based on Table 1. predict the most likely mass, in grams, of water in the
mixed sample. Explain your answer using specific numbers from Tablel.

answer: c. the experiment shows that the red substance experienced a chemical change.

explanation: chemical change is the change in which chemical composition of the substance changes. physical change is the change in which there is no change in chemical composition.

chemical changes are accompanied by following changes:

a) precipitate formation

b) energy is released or absorbed

c) formation of bubbles

d) change in color

as it is given that the red color has disappeared and there is production of gas, it means the red substance has undergone a chemical change.
