One student was adamant that the bag and its contents should have lost mass. She argued that a solid had changed to a gas; thus a loss in mass. How would you respond to this student?
A) She is correct; gasses have less mass than solids.
B) She is incorrect; the mass of the reactants equals the mass of the products.
C) She is correct; the mass of a solid plus water is more than a liquid plus gas.
D) She is correct; the gas is released from the bag resulting in less total mass.
