What did the gas bubbles observed in the bath bomb experiments indicate?

• That the water temperature was decreasing

• That a chemical reaction was occurring

• That the bath bomb was breaking into pieces

• That the bath bomb was freezing

Why do students record the mass of the whole system before and after the reaction?

• To see how much water the bath bombs absorbed

• To ensure the bottle cap is tightly on

• To determine if new matter was added or gas was formed

• To compare the weight of the dry and wet bath bombs

What does hearing a hiss when opening the bottle cap indicate?

What key idea explains why the mass decreased when the bottle cap was opened?

• The water evaporated inside the bottle.

• Gas is matter and has mass, so when it escapes, mass decreases.

• Bubbles dissolved into the water, causing less mass.

• The bath bombs absorbed more water, decreasing mass.

How can you say that gas has mass in the investigation?

• The mass decreases after the cap is removed and gas escapes.

• The water level rises after adding the bath bombs.

• The bubbles make the bottle lighter.

• The fizzing sound is an indication of mass.

What does the experiment show if the mass of the closed system does not increase?

• The bath bomb is too small.

• The water absorbed the gas.

• The gas evaporated quickly.

• No new matter has been added.

If the mass of the system remains the same before and after mixing the bath bombs with water, what conclusion can be drawn?

• The reaction did not produce any gas.

• The bath bombs did not dissolve properly.

• No new matter was created; the gas was already present.

Why is it important to record the mass of the system after releasing the gas?

• To see if the gas will react with the atmosphere

• To determine how much gas fits inside the bottle

• To verify if the gas is heavier than the bath bomb

• To show that the gas has mass, and its release affects the total mass

How does the experiment with the bath bombs and water demonstrate the law of conservation of mass?

• Mass decreases as gas is produced.

• Mass increases with the formation of bubbles.

• Mass remains constant when no matter is added or removed from the system.

• Mass changes based on the reaction’s intensity.
