Which of the following could be the hypothesis supported by an investigation that demonstrates the law of conservation of mass in relation to chemical reactions? A. If the reaction obeys the law of conservation of mass, then mass will be the same before and after the reaction.
B. If the reaction obeys the law of conservation of mass, then mass will increase after the reaction.
C. If the reaction obeys the law of conservation of mass, then mass will be different before and after the reaction.
D. If the reaction obeys the law of conservation of mass, then mass will decrease after the reaction.
