This statement is known as the Law of Conservation of Mass or Lavoisier's Law. At the time it was formulated, its validity was contested, since when burning different substances it was possible to observe an increase or decrease in mass. To exemplify this phenomenon, consider the two identical scales I and II shown in the following figure. Identical masses of coal and steel wool were placed on the plates of these scales, distributed as follows: plates A and C: coal; plates B and D: steel wool. Next, under the same reaction conditions, the materials contained in B and C were burned, which caused an imbalance in the scales. To restore balance, procedures for adding and removing masses will be necessary, respectively, in the following plates: a) A and D. b) B and C. c) C and A. d) D and B.
