Look at the pictures above. A shows the bag before the vinegar and baking soda are mixed together, and B shows it after they are mixed together. In which picture do the contents of the bag have the greater mass?

• The mass is greater in A—before they are mixed.

• The mass is greater in B—after they are mixed.

• The mass is the same in both.

• The mass depends on the temperature.

Two different liquids are poured together. Bubbles and a mist forms. A few minutes later, the solution is weighed, and the weight is less than before the liquids were mixed. Why?

• Atoms were destroyed in the mist.

• Atoms became lighter when they turned into a gas.

• Some atoms escaped into the air.

• Some of the atoms became brand new substances that weigh less.
