Ms. Jacobson is demonstrating a chemical change for her class She places 15 g of baking soda into a beaker. Next, she add 15g (grams) of vinegar to
the same beaker. When the two substances make contact, they bubble and fizz. She
places the beaker on the balance and records a mass of the solution in the beaker is less
than 30g.

Why is the mass of the solution in the beaker less than 30g?

A: The Gas That was produced left the beaker

B: the new products have less mass than the original reactants

C: Mass is always lost in a chemical reaction

D: the gas was not working properly
