Question

I still think of mines two liquids in a bakers observes that the mass of the combine liquids is less than the mass of the two separated liquid system student claims that this observation shows that matter is not conserved and chemical reactions which statement explains why the student claims is incorrect the product contains fewer atoms in the reactants. The reactants did not change the physical properties of the liquids. The reaction produced a gas that escaped the beaker. The combine liquid was warmer than the two separated liquids.

Answer 1

The statement that explains why the student's claim is incorrect is: The reaction produced a gas that escaped the beaker. This is because the loss of mass observed could be due to the escape of a gas produced during the chemical reaction, rather than a violation of the conservation of matter principle.
