A student combines two liquids in a beaker. She
observes that the mass of the combined liquid is less
than the mass of the two separate liquids. The
student claims that this observation shows that matter is
not conserved in chemical reactions. Which statement
explains why the student’s claim is incorrect? (1 point)
The reaction produced a gas that
escaped the beaker.
The reaction did not change the physical
properties of the liquids.
The combined liquid was warmer than
the two separate liquids.
The product contained fewer atoms than
the reactants.
