Meredith mixes together 5 grams of baking soda and 5 grams of vinegar in a test tube that is not sealed. She then weighs the product and finds that it weighs 9 grams. Mathew conducts the same experiment, except in a sealed bag. He finds that 5 grams of baking soda and 5
grams of vinegar will result in 10 grams of product. Which of the following might account for their different findings?
O A. Some of the mass was created during the reaction between vinegar and baking soda in the bag.
OB. Some of the mass of the reactants was converted to light.
O C. Some of the mass escaped from the test tube as a gas before it was massed.
OD. Some of the mass from the test tube was destroyed.
