Question 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) Responses The reaction produced a gas that escaped the beaker. The reaction produced a gas that escaped the beaker. The product contained fewer atoms than the reactants. The product contained fewer atoms than the reactants. The combined liquid was warmer than the two separate liquids. The combined liquid was warmer than the two separate liquids. The reaction did not change the physical properties of the liquids. The reaction did not change the physical properties of the liquids.
The correct statement is: The reaction produced a gas that escaped the beaker.
This is the correct statement because if a gas was produced during the chemical reaction and escaped the beaker, it would result in a decrease in mass of the combined liquid compared to the mass of the two separate liquids. This does not mean that matter is not conserved, as the gas that escaped is still part of the chemical reaction and contributes to the overall mass of the reactants and products.
