Read the scenario.
A student scientist decides to test the law of conservation of mass. He combines 12 g of one chemical with 10 g of another chemical. When the two chemicals combine, bubbles form and gas is released. The student scientist measures the mass of the two chemicals together and discovers that it is 19 g.
Which of the answer choices describes the most probable reason why the mass of the combined chemicals did not equal 22 g?
The law of conservation of mass does not apply to chemical reactions.
Some of the chemicals’ mass was changed into a gas state and was not measured.
Some of the chemicals’ mass shrank to a smaller size when the chemical reaction occurred.
The law of conservation of mass is false.
