What happens when a bath bomb is added to water?

Select all statements that are true.

• When a bath bomb is added to water, it dissolves and breaks down into particles.

• When a bath bomb is added to water, it does not change.

• When a bath bomb is added to water, fizzing and bubbling show a gas is produced.

Where is the gas coming from when a bath bomb is added to water?

• When a bath bomb is added to water, a gas is produced from new matter that was somehow added to a closed system (sealed bottle).

• When a bath bomb is added to water, a gas is produced from matter that was already inside the closed system (sealed bottle).
